You are correct, BUT usa-zip-code dot com seams to stay, I guess the contrib who removes others must own that site or is getting money from them. They are a FOR PROFIT COMPANY who makes money off of selling PUBLIC information. — Preceding unsigned comment added by 74.129.112.81 ( talk) 01:58, 6 February 2013 (UTC)
There are millions of ZIP Code lookups on the internet. I don't think it's necessary for Wikipedia to link to every one of them. I believe that we should stick with the official lookups on the USPS website. Many of the others that seem to pop up reguarly are pretty spammy.
As it name implies, USZip(.)com is all about U.S. Zip code data and will provide users with geographic and several demographic factors for a given zip code using a clear and intuitive AJAX based user interface. The data is compiled from the public domain US Census Bureau 2000 ZIP code tabulations.
We would appreciate if you will consider our entry and objectively compare it to other non-governmental sources that are listed such as the 'ZipCode Finder', and decide which resource provides more relevant information, ease of use and less aggressive advertising to better serve the WikiPedia audience.
Thanks in advance for your time and consideration. —Preceding unsigned comment added by 80.230.255.60 ( talk) 11:14, 4 May 2008 (UTC)
Regarding your spyware threat concerns, I can assure you our family of reference related websites are 100% safe and secure. Our websites (lead by Abbreviations(.)com, an acronyms and abbreviations directory edited by volunteering editors) are serving millions of visitors from all over the world and we've been running our online business for more than 7 years now without a single malicious code complaints.
We'll be waiting for more feedback before adding USZip(.)com to the external links section.

If you're interested in a DMOZ link then Top: Reference: Directories: Address and Phone Numbers: Postal Codes is probably going to be the closest match. The link isn't very easy to find directly from the DMOZ home page but a direct link from this article might allow people to find what they're looking for. Unfortunately, the DMOZ page is not limited to just US zip codes. It postal codes from other countries as well.
If you're interested in a Google link then free zip code database is probably the most relevant search term for this particular article. Please note, if you remove the word "free" from the search query you'll simply get a ton of commercial websites trying to make a fast buck (sometimes hundreds of dollars) for data and services that are (obviously) available for free. -- PopularData ( talk) 03:12, 26 June 2008 (UTC)
Since no new discussion seems to have happened here I have removed the old/incomplete US Census bureau links. People would be better off searching on Google, DMOZ, etc themselves. If someone wants to add those searches as ELs feel free (see notes above). I have also removed the USZIP link as it really isn't relevant to this article (ie. USPS website has it covered). Perhaps it is more relevant to an article about the US Census or US demographics? -- PopularData ( talk) 04:58, 1 August 2008 (UTC)
The correct name for the "zip plus four" code is "ZIP + 4" - please note the spaces before and after the plus sign. 21:40, 26 January 2007 (UTC) R. West
Is it possible for a ZIP code to be entirely removed, I assume by merging into another zip? If so, need to update with the fact it happens and how. -- Ward99 — Preceding undated comment added 21:27, 19 February 2007
Does anyone know what the USPS recommended fonts for mailings are? — Preceding unsigned comment added by 64.40.46.82 ( talk) 17:37, 9 March 2007
I need to assign a red/blue condition in an SCF map, much like a red and blue state election map, except it would be red and blue SCF's. Simple map, no highways etc, don't even need state borders and SCF areas can be approx. Any suggestions how I might do that without hiring a marketing/mapping company?
Funny the online USPS mailing standards don't specify a preferred font. USPS has been using OCR since the 70's, surely they can handle all routine common fonts, but they should reject artsy/calligraphy fonts on bulk mailings, in my opinion.

Looks like 65.182.233.93 has been spamming PopularData.com on the page repeatedly, and removing the "If you want to add an external link to this list, please discuss it on the talk page first. Otherwise, it may be immediately removed. Thank you." comment. Polpo ( talk) 17:36, 23 May 2008 (UTC)
One of the main problems here is that we have a bunch of people with a bit of a "god complex" here. Just read the page history and you can see examples of long time editors adding USEFUL links only to see them removed a day or so later. Anyone who bothered to do even a little research would see that the populardata.com website is a FREE, opensource site. It is featured on MANY blogs around the internet, has been published in multiple magazine articles, and even a few books. The site is clean. Futhermore, I feel it is an EXTREMELY relevant site. It is perhaps one of the best sources of FREE up-to-date zip code database data. Please leave it intact. Thank you. —Preceding unsigned comment added by 65.182.233.93 ( talk) 17:18, 26 May 2008 (UTC)
I have reviewed the ELs and can not any ELs that provide good raw zip code data. Web services are fine for most but as a programmer I am looking for RAW data. The only raw data available in the ELs appears to be the US Census data. I have downloaded the census data and it appears to be VERY out of date. I did some research (based on the claims above) and it does appear to be a relevant (at least Google thinks so) source of zip code data. I would suggest to the person(s) running populardata.com that if they added a web service or something to their site it might be more easily accepted? I don't care for such a thing myself. There are HUNDREDS of sites out there with web portals and services for zip code info. I just want a database to include in my own programs. Just my two cents. I vote to put it back in. Or, should I just add it back in? One person takes links out, another adds them back in. I'm new (to this article) but I fail to see the "process" here? Andrew —Preceding unsigned comment added by 72.11.123.50 ( talk) 22:43, 6 June 2008 (UTC)
I see that the PopularData.com external link has been removed again... for no real reason. I would kindly request that Wehwalt stop removing it. I welcome open discussion on the subject and encourage anyone interested to do a little research and explain to me why its not relevant. Also, while I'm on the topic of relevant links I would like to point out that the external link to the census bureau data is seriously out of date. Not only is the data over EIGHT YEARS old... it was never complete to begin with! The census bureau themselves state this in the following link:
http://www.census.gov/cgi-bin/geo/tigerfaq?Q16
I don't see anyone anxious to remove that link (and it probably should be) so it makes absolutely no sense to remove the PopularData link. The PopularData link contains information that is more complete, and more accurate. Since one single individual decided to remove the link I have added the link back in. I welcome discussion as to why anyone feels it is not relevant to this article. I would also like to thank the person above (Andrew) for his comments. I don't have any immediate plans to add any sort of webservice since there are a TON of sites out there that already. What I provide is complete and raw data for download (for free). I do appreciate the suggestion though. If that was all it took to have people stop removing the link I could easily do that. The code for such a lookup service would take me less than 10 minutes to write. *shrug* -- PopularData ( talk) 05:50, 19 June 2008 (UTC)
I agree, PopularData.com should not be adding it due to a direct conflict of interest. I disagree with you being judge, jury, and executioner though. Who are these editors? What are their names? Time for a vote? —Preceding unsigned comment added by 72.11.123.50 ( talk) 16:19, 19 June 2008 (UTC)
Wehwalt, you clearly need to do some research. I personally am not associated with PopularData (just a supporter) so no need to worry about "sockpuppets". For an attorney you don't argue very well. WP is not a democracy but its not a dictatorship either. Based on your logic are you saying that if two or more people disagree with your changes they should be undone? That's just silly. Furthermore, your talk about "software packages" is silly as well. There isn't a software package on that entire site. Just raw data in text form. :-) Do some research and stop grinding that axe. :-) -Andrew —Preceding unsigned comment added by 72.11.123.50 ( talk) 17:11, 19 June 2008 (UTC)
Andrew, would you please refrain from undoing the changes. I am trying to "follow procedure" even though I disagree with some of what Wehwalt is saying. We have had a discussion over on a separate WP page and he has recommended I come over here and post my points. It seems to me (on the surface anyway) that nobody has a problem with the populardata.com link itself but with the lack of proper procedure or asking for permission (or whatever). That being said, I spent some time today reading through the dispute resolution policies. That being said, I am "officially" requesting that someone review and add the following link to the "External Links" section of this article and also consider my other points:
All that being said. My website is NOT a product... simply a resource. It is NOT a program... simply raw data. So, while you and I seem to be in a "battle over procedure" and we're clearly both being stubborn. I propose that we set our differences aside for a moment. I would like to extend the olive branch and ask that you please review the populardata.com link. Here are the reasons why I personally feel it should be submitted (Andrew, I have included some of your points as well, thank you):
1. If you go to Google and search for "free zip code database" or even "zip code database" you will find that PopularData.com consistently shows up on the first page for those phrases and several variations. For the phrase mentioned above, I think it comes in around 4th place (just above the wikipedia article). If Google considers it "relevant" I think it deserves a second look and consideration for inclusion here.
2. If you LOOK at the populardata home page itself you will see that NOWHERE on that page is the phrase "zip code database" or even "zip code". The REASON the site ranks so high on Google is because a large portion of the web community out there have linked to my site in their blogs. Google considers this "link relevance" (ie. many people talking about the same thing and pointing to the same place). I would be happy to provide a list of referring links to back this up if necessary.
3. The PopularData.com website is free for everyone. While many, MANY, other sites out there are requiring payment for zip code databases, etc... this site is (and always has been) free. For this reason alone, I feel it could be a valuable addition to the Zip Code article on Wikipedia.
4. In addition to this site being published in multiple blogs and papers it has also been published in several books. I feel that this further makes the case for it being a relevant link here.
I would not like to discuss the CURRENT external links on the Zip Code article:
The article currently contains a link to ( http://www.aresllc.com/zip-codes-finder/)... if you go to this link and try searching for a zip code, you will find the site is malfunctioning. Regardless of what you decide on my link, you should probably remove this one. It looks like the USZip.com serves the exact same purpose anyway.
It is also worth mentioning that I could easily provide that same service on a page on my site (less than a day to implement) if you feel it actually adds value and would make my site more worth of submission. (kill 2 birds with one stone?)
The article also contains a link to (Zip code data sets) from the census bureau. This is the only link on this article that contains downloadable zip code data. This seems to indicate that there is already a "concensus" that downloadable zip code data IS valuable to this WP article. Unfortunately, the Census data is incomplete and out of date. The census bureau also makes mention of this on their website.
I respectfully propose that the http://www.populardata.com link be added to this article or possibly even replace the census bureau website as the data is complete, more accurate, and more up to date.
(There Wehwalt, how did I do?) ;-) -- PopularData ( talk) 22:52, 20 June 2008 (UTC)
Wehwalt, I will attempt to address your points in order:
It is NOT the same data as on the Census Bureau site. A download of both sets of data will easily confirm this. As of this writing, the main data on the PopularData.com site is about 1-2 years old. An update is actually scheduled before the end of the month which will bring the database current to 2008. Zip codes don't change on a month-to-month basis (contrary to what may pay sites would have you believe, most of them bundle in telephone area code data which DOES update often) so I typically queue up many of the changes, confirm them, and roll it all out at once.
I am uncertain as to how to address your copyright question other than to say I have always offered all of the data on the site free and without any catches. I suppose if that were to cease, someone could simply discuss and remove the EL?
I believe the link DOES help a lot of the readers of this article and would go as far as to say it is probably more than you realize. If someone wants to do a simple zip code lookup, they just go to the US Post Office website (USPS.COM). There are hundreds (if not thousands) of zip code lookup sites on the internet but very few actually offer the complete set of data. In short, how do you think all of those zip code lookup websites work? ;-) (Ironically, I can trace many of them back to downloads from my site) LOL
I have read the WP:EL and I believe this link falls under those standards just as much as any of the links you have already accepted for this article. I believe that the link to the Census Bureau data already establishes the concensus that being "confronted with a database download" is acceptable. Furthermore, if I were to play Devil's advocate for a moment, I would question the relevance of all zip code lookup websites (other than the USPS.COM website). Anyone can go to Google Maps, type in a zip code, and see a map. That's about all most of the zip code lookup links do. (one could argue the point that some links show demographic data, but now we're not talking about zip codes anymore, are we?) :)
I hope that I have satisfied your questions but let me know if you have more. If you truly have nothing against the site and you are truly considering what I have to say without prejudice then I think you'll find my intentions are sincere. Clearly I have jumped through more than enough hoops here. :-)
You have stated that you're pretty much the only editor on this article so you tell me what's next? -- PopularData ( talk) 03:17, 21 June 2008 (UTC)
Thank you for your input Herbythyme. So, it seems like what you are suggesting is that the link be rejected based on what has happened in the past rather than the fact that I have finally come around to discuss it (in great detail) here on the talk page? While I respect your opinion I feel that this article in particular seems a bit bias. Up above I have discussed several of the external links and I am curious as to why the "aresllc" link is still here? Right at the top someone called them a link spammer yet they're still allowed? The lookup service at that link is broken by the way (pukes out a bunch of PHP errors when you try to look up a zip code). So, why aren't the "rules" the same for everyone? :-) I respectfully disagree with you that the issue here is the breach of policy. At this point in time, wouldn't the issue be what is best for the overall quality of the article? I have not re-added the PopularData.com link ever since it was pointed out that it was COI. I still feel the link is valuable to this article though, especially when examining and considering the links that have been allowed here. Can someone tell me if there is more to the story with the "aresllc" link? I don't see any discussion of it on this page... yet it was allowed? I'm new here so I could have easily missed something. If so, please let me know. -- PopularData ( talk) 16:41, 23 June 2008 (UTC)
Why have all the individual US State ZIP Code entries been deleted? -- 130.156.169.212 15:26, 24 April 2007 (UTC)
The way I read
When a sectional center facility's area crosses state lines, that facility is assigned separate three-digit prefixes for the states that it serves; thus, it is possible to identify the state associated with any ZIP Code just by looking at the first three digits.
I should be able to look at the first three digits of any ZIP, say 06390 as is mentioned a bit later, and map 063 to the state for Fishers Island, which should be NY. But the vast majority of the 063 codes are in Connecticut. For example, 06389 is for Yantic, CT. (These codes were looked up in the latest City/State product from the USPS. You can confirm the assertion by going to the USPS zip+4 lookup page at http://zip4.usps.com/zip4/welcome.jsp and looking for PO Box 1 in the 06389 and 06390 ZIPs. The former comes back in CT, the latter in NY.)
So either I am reading the sentence above incorrectly, or it has ceased to be true. I only find 8 ZIPs in the current data where there is ambiguity on the first three digits, and only 4 different 3-digit prefixes where all 8 ZIPs appear. So the statement is almost true. But I think the statement needs some rewording, or we run the risk of misleading people.
Jpl 17:57, 21 November 2006 (UTC)
Fishers Island is the exception to most of the rules. Plus there used to be some DC branches in Virginia, at government offices and the like. As far as I know, Fishers Island is the only fully independent post office, with its own postmaster, with an "out of state" ZIP. Maybe, Jpl, you could post the excepions and we could discuss?-- Wehwalt 15:41, 8 December 2006 (UTC)
WE MUST SOLVE THIS ZIP CODE CONNUNDRUM
Here are the exceptions from the May 2007 City/State product from the USPS.
'06'=>[3,'CT'],
'063'=>[4,'CT'],
'0639'=>[4,'NY'],
'834'=>[4,'ID'],
'8341'=>[5,'ID'],
'83414'=>[5,'WY'],
'967'=>[4,'HI'],
'9679'=>[5,'HI'],
'96799'=>[5,'AS'],
'969'=>[4,'GU'],
'9694'=>[5,'FM'],
'96940'=>[5,'PW'],
'9695'=>[4,'MP'],
'9696'=>[4,'MH'],
'9697'=>[4,'MH'],
The way to read them is: everything starting with the prefix to the left of the => is the state that is the second item in brackets, but you must check prefixes of the length that is the first item in brackets for exceptions. So '06' is 'CT' unless a prefix of length 3 is also in the table, and '063' is also 'CT' unless there is a prefix of length 4 in the table, and '0639' is 'NY', and since that is already a prefix of length 4, there are no other exceptions. A bit clunky, but quite compact, since many states are already unambiguous with prefixes of length 2. So the only exceptions to the "3 digits is sufficient" rule are entries of length 4 or more, all of which appear above (as of May 2007, anyway). Most exceptions involve "territories", like AS (American Samoa), GU (Guam), FM (Federated States of Micronesia), MH (Marshall Islands), MP (Northern Mariana Islands) or PW (Palau), but the first two exceptions are in the 50 states. So, although exceptions are rare, we dare not suggest that 3 digits are always sufficient to identify state. Jpl 12:51, 22 May 2007 (UTC)
This situation usually seems to come up when a city is very close to a state line. These exceptions came from grinding through a database of 15 million US business addresses, and noting exceptions to the one-state-per-3-digit-ZIP rule. The Census Bureau web site says that even 5-digit ZIP codes can cross state lines.
It also looks like 297 can appear in both NC and SC.
I could use a solidly reliable 3-digit ZIP vs. state table. Anyone know a current, free source? None of the listed links have it; they're either out of date or search-only.
I put a {{fact}} tag on that portion of the article. -- John Nagle ( talk) 07:07, 29 December 2007 (UTC)
There are two US Postal Service products that I use regularly. Neither is free or redistributable. The City State product is described as
a comprehensive list of ZIP Codes with corresponding city and county names. This file also contains other names by which a Post Office may be known.
The ZIP + 4 product has a record for every ZIP+4 add on. Samples of the files are available at the referenced websites. It is tempting to think of these files as defining official USPS policy, but the accompanying documentation is fairly sketchy about precise definitions, so what I say here is what I have inferred from these files, not official policy. The ZIP + 4 product stores 6-character City State Keys to identify the bulkier city and state names stored in the City State product. Although the City State product has default preferred names for all the names by which a Post Office may be known, the ZIP + 4 product sometimes overrides that default, as is mentioned elsewhere on this talk page. If one uses the USPS ZIP Code Lookup page as defining policy, then one can confirm that the City State Keys from the ZIP + 4 product are, indeed, what the USPS wants to see used. And, using the same site, we can determine that it is the state from the City State product, not the state stored in the ZIP + 4 product, that the USPS wants to appear on an envelope. With all this as preface, we need some precision when discussing what is meant by a "ZIP to state" table. If what is wanted is a mapping from ZIP code to the state the USPS wants to appear on an envelope, then the City State product is adequate, and the only exceptions to the 3 leading digits of ZIP Code establishing state are those I itemized above (at least as of the January 2008 City State file). If what is wanted is a mapping from ZIP Code to the state to which that envelope would be delivered, it does not exist. I counted 160 ZIP Codes in the January 2008 ZIP + 4 file that spanned two or more states, 4 of which, 30559, 51640, 57717 and 82082, spanned three states. I am quite certain that no ZIP Code + ZIP 4 add on would span multiple states, but I didn't bother to check. Unless the USPS made an official proclamation that that were the intent, confirmation might just be an accident, or disproof might just be dirty data.

Mail from the US to Canada may bear a US POSTNET code such as 00101-2406 for a Canadian postal code which begins M6R. These codes are not listed on the USPS web site, but are used internally by the USPS to machine-sort mail from the US to other countries. Is there a list of these codes? -- Eastmain 03:38, 17 January 2007 (UTC)
Hi! I have a few basic questions which I couldn't answer by reading the article:
Thanks in advance! -- Jaba82 18:05, 18 March 2007 (UTC)
I don't bother to put the two-letter state abbreviation anymore. It isn't needed. The zip code sends the letter to the particular post office. Such as Joe Brown 123 any street Raleigh 28525
All my mail seems to get there just fine. Putting "Raleigh, NC 28525 " is redundant. My letter is going to the 28525 post office in Raleigh. The sorting machine already knows where 28525 is. I don't have to tell it. — Preceding unsigned comment added by 24.74.223.213 ( talk) 07:50, 16 February 2014 (UTC)
I think the information about zip codes 10048 (World Trade Center) and 77230 (post-Katrina refugee shelter at the Houston Astrodome) should be moved from section 2.2 (Structure and Allocation, by type/use) to section 4 (pop culture). 10048 is not a good example of a Unique ZIP code (it is currently classified as Standard, and may have been Unique, Standard, or P.O.-box-only prior to the destruction of the twin towers). The class of 77230 at its creation is similarly unknown (to me, at any rate). These unclear examples of ZIP class don't belong in a section meant to describe ZIP code types or classes. Pop Culture would be a nicer home for them.
More generally, there appears to be some confusion regarding ZIP codes that are "unique" in some common meaning of the word, as opposed to "Unique" in the specific sense of the ZIP code class assigned by the USPS. In particular, the fact that there is a one-to-one correspondence between a ZIP code and a particular building, campus, or complex does not mean that the ZIP code in question is classified as Unique by the USPS. Perhaps the word "unique" should be capitalized throughout the article when referring to the USPS classification; alternately or in addition, synonyms or rephrasings could be used to indicate broader or more casual meanings.
216.231.50.177 14:54, 23 March 2007 (UTC)
Update: No objections; changes made.
216.231.50.177 09:47, 28 March 2007 (UTC)
Most of the many changes made by 199.72.40.115 on 17:14, 1 June 2006 were erroneous, and most of them are still present in this article. Here's the revision I'm referring to. I corrected his addition of "No." which altered the meaning of the algorithm on bar codes, making it incorrect. However, I don't have the patience to systematically change all the references to "ZIP code" to the proper "ZIP Code" that was formerly used in the article.
It is unfortunate that his edit was not immediately reverted. It appears the only valid improvement he made was to change "US" to "U.S."
In the course of looking for the edit that introduced the "No." error, I also noticed a significant vandalism-related deletion, and the person who undid the vandalism that was introduced did so by manually deleting it rather than reverting to restore the deleted text, so the section on Postal Abbreviations was removed. Perhaps that section is off-topic for this article anyway.

How do letters map to numbers in a ZIP+4? — Random832 21:26, 8 October 2007 (UTC)
There's a paragraph in the referenced section that includes a few examples of ZIPs where the postal place name (e.g., Kirkwood NJ) refers to a much larger municipal jurisdiction (e.g., Evesham Township, New Jersey). After that section, the paragraph includes two further anecdotal examples (one about the Town of LaGrange, NY and one about Armstrong Township, IN).
I propose deleting those two examples.
In the case of the Armstrong Township example, I believe that the author is mistaken. I went to the Vanderburgh County web site, got a map of the county's eight townships which showed major roads only, and then went to Google Maps in order to assemble a list of a dozen prominent roads in that part of the county which could conceivably fit the description of "Armstrong, Indiana" (as described by Rhatsa26WD). I then went to USPS.com and did ZIP searches for those roads, and the only ZIP codes that were returned were 47720 and 47725, not the 47617 listed in this paragraph. (By the way, the 47617 referenced in this article maps to HATFIELD IN, in an adjacent county.) Furthermore, the 47720 and 47725 that USPS.com returned do not map to a postal place name of ARMSTRONG IN but instead are EVANSVILLE IN postal addresses. Perhaps the mail is being delivered successfully to postal customers in Armstrong Twp addressed as "Armstrong, IN 47617", but successful delivery does not mean that the post-office name and ZIP code are correct as written.
In the case of the LaGrange example, the facts as presented are more or less correct (except "Lagrangeville," the postal place name, is not spelled with a mid-word capital G), but the situation is not all that unusual. It's an example that is matched in several states where the political boundaries of a "town" (or "township") do not correspond to a post-office name in its vicinity.

I suggest we consider deleting or radically scaling back on this section. It really isn't encyclopedic, when you come down to it. I think it is sufficient if we note that ZIP Codes were not meant to follow municipal lines, give a couple of examples, briefly, and let it go.-- Wehwalt ( talk) 17:48, 1 January 2008 (UTC)
The article currently states in an unsourced paragraph:
By the early 1960s a more general system was needed, and on July 1, 1963, non-mandatory ZIP codes were announced for the whole country. Robert Moon, an employee of the post office, is considered the father of the ZIP code. He submitted his proposal in 1944 while working as a postal inspector.
I just watched a classic episode of CBS's I've Got a Secret (a primetime nationwide U.S. show) and they had on one Bentley Hahn of Springfield, Virginia, whose secret was that he alone came up with the idea for the zip code. No other information was revealed about him, his role or his position at the postal servcie. There is a separate stub on Robert Moon with more about him inventing the zip code. Need I say there's an apparent contradiction here. Google searches are equally contradictory, with separate sources detailing each, separately, as the inventor of the zip code. In any event, the reference, should someone more familiar with this material wish to use it, would be <ref>Bentley Hahn appearance on [[CBS]]' ''[[I've Got a Secret]]'', November 6, 1963. Secret listed as inventor of the ZIP code. Rebroadcast on [[Game Show Network]] on March 4, 2008.</ref>-- Fuhghettaboutit ( talk) 01:44, 6 March 2008 (UTC)

The trivia/in popular culture section is starting to get out of hand. There are millions of cultural/TV references to ZIP codes out there, and most of the ones that are mentioned are minor and irrelevant to the general topic. I propose that the list either be deleted or drastically reduced, and perhaps a prose section can be added on the significance of ZIP codes in TV and popular culture. -- TheCatalyst31 Reaction• Creation 22:58, 26 June 2008 (UTC)

Section 2 under "By type/use" says: "There are four types of ZIP codes: Unique..., P.O.-box-only..., Military... and Standard..." but then the sub-section entitled "Non-standard examples" reads: "A few ZIP codes fall outside the three types..." . . . jg ( talk) 18:29, 8 July 2008 (UTC)

You are correct, BUT usa-zip-code dot com seams to stay, I guess the contrib who removes others must own that site or is getting money from them.

There are millions of ZIP Code lookups on the internet. I don't think it's necessary for Wikipedia to link to every one of them. I believe that we should stick with the official lookups on the USPS website. Many of the others that seem to pop up reguarly are pretty spammy.
As it name implies, USZip(.)com is all about U.S. Zip code data and will provide users with geographic and several demographic factors for a given zip code using a clear and intuitive AJAX based user interface. The data is compiled from the public domain US Census Bureau 2000 ZIP code tabulations.
We would appreciate if you will consider our entry and objectively compare it to other non-governmental sources that are listed such as the 'ZipCode Finder', and decide which resource provides more relevant information, ease of use and less aggressive advertising to better serve the WikiPedia audience.

If you're interested in a DMOZ link then Top: Reference: Directories: Address and Phone Numbers: Postal Codes is probably going to be the closest match. The link isn't very easy to find directly from the DMOZ home page but a direct link from this article might allow people to find what they're looking for. Unfortunately, the DMOZ page is not limited to just US zip codes. It postal codes from other countries as well.
If you're interested in a Google link then free zip code database is probably the most relevant search term for this particular article. Please note, if you remove the word "free" from the search query you'll simply get a ton of commercial websites trying to make a fast buck (sometimes hundreds of dollars) for data and services that are (obviously) available for free. -- PopularData ( talk) 03:12, 26 June 2008 (UTC)
Since no new discussion seems to have happened here I have removed the old/incomplete US Census bureau links. People would be better off searching on Google, DMOZ, etc themselves. If someone wants to add those searches as ELs feel free (see notes above). I have also removed the USZIP link as it really isn't relevant to this article (ie. USPS website has it covered). Perhaps it is more relevant to an article about the US Census or US demographics? -- PopularData ( talk) 04:58, 1 August 2008 (UTC)

Funny the online USPS mailing standards don't specify a preferred font.

One of the main problems here is that we have a bunch of people with a bit of a "god complex" here. Just read the page history and you can see examples of long time editors adding USEFUL links only to see them removed a day or so later. Anyone who bothered to do even a little research would see that the populardata.com website is a FREE, opensource site. It is featured on MANY blogs around the internet, has been published in multiple magazine articles, and even a few books. The site is clean. Futhermore, I feel it is an EXTREMELY relevant site. It is perhaps one of the best sources of FREE up-to-date zip code database data. Please leave it intact. Thank you. —Preceding unsigned comment added by 65.182.233.93 ( talk) 17:18, 26 May 2008 (UTC)
I have reviewed the ELs and can not any ELs that provide good raw zip code data. Web services are fine for most but as a programmer I am looking for RAW data. The only raw data available in the ELs appears to be the US Census data. I have downloaded the census data and it appears to be VERY out of date. I did some research (based on the claims above) and it does appear to be a relevant (at least Google thinks so) source of zip code data. I would suggest to the person(s) running populardata.com that if they added a web service or something to their site it might be more easily accepted? I don't care for such a thing myself. There are HUNDREDS of sites out there with web portals and services for zip code info. I just want a database to include in my own programs. Just my two cents. I vote to put it back in. Or, should I just add it back in? One person takes links out, another adds them back in. I'm new (to this article) but I fail to see the "process" here? Andrew —Preceding unsigned comment added by 72.11.123.50 ( talk) 22:43, 6 June 2008 (UTC)
I see that the PopularData.com external link has been removed again... for no real reason. I would kindly request that Wehwalt stop removing it. I welcome open discussion on the subject and encourage anyone interested to do a little research and explain to me why its not relevant. Also, while I'm on the topic of relevant links I would like to point out that the external link to the census bureau data is seriously out of date. Not only is the data over EIGHT YEARS old... it was never complete to begin with! The census bureau themselves state this in the following link:
http://www.census.gov/cgi-bin/geo/tigerfaq?Q16
I don't see anyone anxious to remove that link (and it probably should be) so it makes absolutely no sense to remove the PopularData link. The PopularData link contains information that is more complete, and more accurate. Since one single individual decided to remove the link I have added the link back in. I welcome discussion as to why anyone feels it is not relevant to this article. I would also like to thank the person above (Andrew) for his comments. I don't have any immediate plans to add any sort of webservice since there are a TON of sites out there that already. What I provide is complete and raw data for download (for free). I do appreciate the suggestion though. If that was all it took to have people stop removing the link I could easily do that. The code for such a lookup service would take me less than 10 minutes to write. *shrug* -- PopularData ( talk) 05:50, 19 June 2008 (UTC)
I agree, PopularData.com should not be adding it due to a direct conflict of interest. I disagree with you being judge, jury, and executioner though. Who are these editors? What are their names? Time for a vote? —Preceding unsigned comment added by 72.11.123.50 ( talk) 16:19, 19 June 2008 (UTC)
Wehwalt, you clearly need to do some research. I personally am not associated with PopularData (just a supporter) so no need to worry about "sockpuppets". For an attorney you don't argue very well. WP is not a democracy but its not a dictatorship either. Based on your logic are you saying that if two or more people disagree with your changes they should be undone? That's just silly. Furthermore, your talk about "software packages" is silly as well. There isn't a software package on that entire site. Just raw data in text form. :-) Do some research and stop grinding that axe. :-) -Andrew —Preceding unsigned comment added by 72.11.123.50 ( talk) 17:11, 19 June 2008 (UTC)
Andrew, would you please refrain from undoing the changes. I am trying to "follow procedure" even though I disagree with some of what Wehwalt is saying. We have had a discussion over on a separate WP page and he has recommended I come over here and post my points. It seems to me (on the surface anyway) that nobody has a problem with the populardata.com link itself but with the lack of proper procedure or asking for permission (or whatever). That being said, I spent some time today reading through the dispute resolution policies. That being said, I am "officially" requesting that someone review and add the following link to the "External Links" section of this article and also consider my other points:
All that being said. My website is NOT a product... simply a resource. It is NOT a program... simply raw data. So, while you and I seem to be in a "battle over procedure" and we're clearly both being stubborn. I propose that we set our differences aside for a moment. I would like to extend the olive branch and ask that you please review the populardata.com link. Here are the reasons why I personally feel it should be submitted (Andrew, I have included some of your points as well, thank you):
1. If you go to Google and search for "free zip code database" or even "zip code database" you will find that PopularData.com consistently shows up on the first page for those phrases and several variations. For the phrase mentioned above, I think it comes in around 4th place (just above the wikipedia article). If Google considers it "relevant" I think it deserves a second look and consideration for inclusion here.
2. If you LOOK at the populardata home page itself you will see that NOWHERE on that page is the phrase "zip code database" or even "zip code". The REASON the site ranks so high on Google is because a large portion of the web community out there have linked to my site in their blogs. Google considers this "link relevance" (ie. many people talking about the same thing and pointing to the same place). I would be happy to provide a list of referring links to back this up if necessary.
3. The PopularData.com website is free for everyone. While many, MANY, other sites out there are requiring payment for zip code databases, etc... this site is (and always has been) free. For this reason alone, I feel it could be a valuable addition to the Zip Code article on Wikipedia.
4. In addition to this site being published in multiple blogs and papers it has also been published in several books. I feel that this further makes the case for it being a relevant link here.
I would not like to discuss the CURRENT external links on the Zip Code article:
The article currently contains a link to ( http://www.aresllc.com/zip-codes-finder/)... if you go to this link and try searching for a zip code, you will find the site is malfunctioning. Regardless of what you decide on my link, you should probably remove this one. It looks like the USZip.com serves the exact same purpose anyway.
It is also worth mentioning that I could easily provide that same service on a page on my site (less than a day to implement) if you feel it actually adds value and would make my site more worth of submission. (kill 2 birds with one stone?)
The article also contains a link to (Zip code data sets) from the census bureau. This is the only link on this article that contains downloadable zip code data. This seems to indicate that there is already a "concensus" that downloadable zip code data IS valuable to this WP article. Unfortunately, the Census data is incomplete and out of date. The census bureau also makes mention of this on their website.
I respectfully propose that the http://www.populardata.com link be added to this article or possibly even replace the census bureau website as the data is complete, more accurate, and more up to date.
(There Wehwalt, how did I do?) ;-) -- PopularData ( talk) 22:52, 20 June 2008 (UTC)
Wehwalt, I will attempt to address your points in order:
It is NOT the same data as on the Census Bureau site. A download of both sets of data will easily confirm this. As of this writing, the main data on the PopularData.com site is about 1-2 years old. An update is actually scheduled before the end of the month which will bring the database current to 2008. Zip codes don't change on a month-to-month basis (contrary to what may pay sites would have you believe, most of them bundle in telephone area code data which DOES update often) so I typically queue up many of the changes, confirm them, and roll it all out at once.
I am uncertain as to how to address your copyright question other than to say I have always offered all of the data on the site free and without any catches. I suppose if that were to cease, someone could simply discuss and remove the EL?
I believe the link DOES help a lot of the readers of this article and would go as far as to say it is probably more than you realize. If someone wants to do a simple zip code lookup, they just go to the US Post Office website (USPS.COM). There are hundreds (if not thousands) of zip code lookup sites on the internet but very few actually offer the complete set of data. In short, how do you think all of those zip code lookup websites work? ;-) (Ironically, I can trace many of them back to downloads from my site) LOL
I have read the WP:EL and I believe this link falls under those standards just as much as any of the links you have already accepted for this article. I believe that the link to the Census Bureau data already establishes the concensus that being "confronted with a database download" is acceptable. Furthermore, if I were to play Devil's advocate for a moment, I would question the relevance of all zip code lookup websites (other than the USPS.COM website). Anyone can go to Google Maps, type in a zip code, and see a map. That's about all most of the zip code lookup links do. (one could argue the point that some links show demographic data, but now we're not talking about zip codes anymore, are we?) :)
I hope that I have satisfied your questions but let me know if you have more. If you truly have nothing against the site and you are truly considering what I have to say without prejudice then I think you'll find my intentions are sincere. Clearly I have jumped through more than enough hoops here. :-)
You have stated that you're pretty much the only editor on this article so you tell me what's next? -- PopularData ( talk) 03:17, 21 June 2008 (UTC)
Thank you for your input Herbythyme. So, it seems like what you are suggesting is that the link be rejected based on what has happened in the past rather than the fact that I have finally come around to discuss it (in great detail) here on the talk page? While I respect your opinion I feel that this article in particular seems a bit bias. Up above I have discussed several of the external links and I am curious as to why the "aresllc" link is still here? Right at the top someone called them a link spammer yet they're still allowed? The lookup service at that link is broken by the way (pukes out a bunch of PHP errors when you try to look up a zip code). So, why aren't the "rules" the same for everyone? :-) I respectfully disagree with you that the issue here is the breach of policy. At this point in time, wouldn't the issue be what is best for the overall quality of the article? I have not re-added the PopularData.com link ever since it was pointed out that it was COI. I still feel the link is valuable to this article though, especially when examining and considering the links that have been allowed here. Can someone tell me if there is more to the story with the "aresllc" link? I don't see any discussion of it on this page... yet it was allowed? I'm new here so I could have easily missed something. If so, please let me know. -- PopularData ( talk) 16:41, 23 June 2008 (UTC)
Why have all the individual US State ZIP Code entries been deleted? -- 130.156.169.212 15:26, 24 April 2007 (UTC)
The way I read
When a sectional center facility's area crosses state lines, that facility is assigned separate three-digit prefixes for the states that it serves; thus, it is possible to identify the state associated with any ZIP Code just by looking at the first three digits.
I should be able to look at the first three digits of any ZIP, say 06390 as is mentioned a bit later, and map 063 to the state for Fishers Island, which should be NY. But the vast majority of the 063 codes are in Connecticut. For example, 06389 is for Yantic, CT. (These codes were looked up in the latest City/State product from the USPS. You can confirm the assertion by going to the USPS zip+4 lookup page at http://zip4.usps.com/zip4/welcome.jsp and looking for PO Box 1 in the 06389 and 06390 ZIPs. The former comes back in CT, the latter in NY.)
So either I am reading the sentence above incorrectly, or it has ceased to be true. I only find 8 ZIPs in the current data where there is ambiguity on the first three digits, and only 4 different 3-digit prefixes where all 8 ZIPs appear. So the statement is almost true. But I think the statement needs some rewording, or we run the risk of misleading people.
Jpl 17:57, 21 November 2006 (UTC)
Fishers Island is the exception to most of the rules. Plus there used to be some DC branches in Virginia, at government offices and the like. As far as I know, Fishers Island is the only fully independent post office, with its own postmaster, with an "out of state" ZIP. Maybe, Jpl, you could post the excepions and we could discuss?-- Wehwalt 15:41, 8 December 2006 (UTC)
WE MUST SOLVE THIS ZIP CODE CONNUNDRUM
Here are the exceptions from the May 2007 City/State product from the USPS.
'06'=>[3,'CT'],
'063'=>[4,'CT'],
'0639'=>[4,'NY'],
'834'=>[4,'ID'],
'8341'=>[5,'ID'],
'83414'=>[5,'WY'],
'967'=>[4,'HI'],
'9679'=>[5,'HI'],
'96799'=>[5,'AS'],
'969'=>[4,'GU'],
'9694'=>[5,'FM'],
'96940'=>[5,'PW'],
'9695'=>[4,'MP'],
'9696'=>[4,'MH'],
'9697'=>[4,'MH'],
The way to read them is: everything starting with the prefix to the left of the => is the state that is the second item in brackets, but you must check prefixes of the length that is the first item in brackets for exceptions. So '06' is 'CT' unless a prefix of length 3 is also in the table, and '063' is also 'CT' unless there is a prefix of length 4 in the table, and '0639' is 'NY', and since that is already a prefix of length 4, there are no other exceptions. A bit clunky, but quite compact, since many states are already unambiguous with prefixes of length 2. So the only exceptions to the "3 digits is sufficient" rule are entries of length 4 or more, all of which appear above (as of May 2007, anyway). Most exceptions involve "territories", like AS (American Samoa), GU (Guam), FM (Federated States of Micronesia), MH (Marshall Islands), MP (Northern Mariana Islands) or PW (Palau), but the first two exceptions are in the 50 states. So, although exceptions are rare, we dare not suggest that 3 digits are always sufficient to identify state. Jpl 12:51, 22 May 2007 (UTC)
This situation usually seems to come up when a city is very close to a state line. These exceptions came from grinding through a database of 15 million US business addresses, and noting exceptions to the one-state-per-3-digit-ZIP rule. The Census Bureau web site says that even 5-digit ZIP codes can cross state lines.
It also looks like 297 can appear in both NC and SC.
I could use a solidly reliable 3-digit ZIP vs. state table. Anyone know a current, free source? None of the listed links have it; they're either out of date or search-only.
I put a {{fact}} tag on that portion of the article. -- John Nagle ( talk) 07:07, 29 December 2007 (UTC)
There are two US Postal Service products that I use regularly. Neither is free or redistributable. The City State product is described as
a comprehensive list of ZIP Codes with corresponding city and county names. This file also contains other names by which a Post Office may be known.
The ZIP + 4 product has a record for every ZIP+4 add on. Samples of the files are available at the referenced websites. It is tempting to think of these files as defining official USPS policy, but the accompanying documentation is fairly sketchy about precise definitions, so what I say here is what I have inferred from these files, not official policy. The ZIP + 4 product stores 6-character City State Keys to identify the bulkier city and state names stored in the City State product. Although the City State product has default preferred names for all the names by which a Post Office may be known, the ZIP + 4 product sometimes overrides that default, as is mentioned elsewhere on this talk page. If one uses the USPS ZIP Code Lookup page as defining policy, then one can confirm that the City State Keys from the ZIP + 4 product are, indeed, what the USPS wants to see used. And, using the same site, we can determine that it is the state from the City State product, not the state stored in the ZIP + 4 product, that the USPS wants to appear on an envelope. With all this as preface, we need some precision when discussing what is meant by a "ZIP to state" table. If what is wanted is a mapping from ZIP code to the state the USPS wants to appear on an envelope, then the City State product is adequate, and the only exceptions to the 3 leading digits of ZIP Code establishing state are those I itemized above (at least as of the January 2008 City State file). If what is wanted is a mapping from ZIP Code to the state to which that envelope would be delivered, it does not exist. I counted 160 ZIP Codes in the January 2008 ZIP + 4 file that spanned two or more states, 4 of which, 30559, 51640, 57717 and 82082, spanned three states. I am quite certain that no ZIP Code + ZIP 4 add on would span multiple states, but I didn't bother to check. Unless the USPS made an official proclamation that that were the intent, confirmation might just be an accident, or disproof might just be dirty data.

Mail from the US to Canada may bear a US POSTNET code such as 00101-2406 for a Canadian postal code which begins M6R.

I don't bother to put the two-letter state abbreviation anymore. It isn't needed. The zip code sends the letter to the particular post office. Such as Joe Brown 123 any street Raleigh 28525
All my mail seems to get there just fine. Putting "Raleigh, NC 28525 " is redundant. My letter is going to the 28525 post office in Raleigh. The sorting machine already knows where 28525 is. I don't have to tell it. — Preceding unsigned comment added by 24.74.223.213 ( talk) 07:50, 16 February 2014 (UTC)
I think the information about zip codes 10048 (World Trade Center) and 77230 (post-Katrina refugee shelter at the Houston Astrodome) should be moved from section 2.2 (Structure and Allocation, by type/use) to section 4 (pop culture). 10048 is not a good example of a Unique ZIP code (it is currently classified as Standard, and may have been Unique, Standard, or P.O.-box-only prior to the destruction of the twin towers). The class of 77230 at its creation is similarly unknown (to me, at any rate). These unclear examples of ZIP class don't belong in a section meant to describe ZIP code types or classes. Pop Culture would be a nicer home for them.
More generally, there appears to be some confusion regarding ZIP codes that are "unique" in some common meaning of the word, as opposed to "Unique" in the specific sense of the ZIP code class assigned by the USPS. In particular, the fact that there is a one-to-one correspondence between a ZIP code and a particular building, campus, or complex does not mean that the ZIP code in question is classified as Unique by the USPS. Perhaps the word "unique" should be capitalized throughout the article when referring to the USPS classification; alternately or in addition, synonyms or rephrasings could be used to indicate broader or more casual meanings.

Update: No objections; changes made.
216.231.50.177 09:47, 28 March 2007 (UTC)
Most of the many changes made by 199.72.40.115 on 17:14, 1 June 2006 were erroneous, and most of them are still present in this article. Here's the revision I'm referring to. I corrected his addition of "No." which altered the meaning of the algorithm on bar codes, making it incorrect. However, I don't have the patience to systematically change all the references to "ZIP code" to the proper "ZIP Code" that was formerly used in the article.
It is unfortunate that his edit was not immediately reverted. It appears the only valid improvement he made was to change "US" to "U.S."
In the course of looking for the edit that introduced the "No." error, I also noticed a significant vandalism-related deletion, and the person who undid the vandalism that was introduced did so by manually deleting it rather than reverting to restore the deleted text, so the section on Postal Abbreviations was removed. Perhaps that section is off-topic for this article anyway.

How do letters map to numbers in a ZIP+4? — Random832 21:26, 8 October 2007 (UTC)
There's a paragraph in the referenced section that includes a few examples of ZIPs where the postal place name (e.g., Kirkwood NJ) refers to a much larger municipal jurisdiction (e.g., Evesham Township, New Jersey). After that section, the paragraph includes two further anecdotal examples (one about the Town of LaGrange, NY and one about Armstrong Township, IN).
I propose deleting those two examples.
In the case of the Armstrong Township example, I believe that the author is mistaken. I went to the Vanderburgh County web site, got a map of the county's eight townships which showed major roads only, and then went to Google Maps in order to assemble a list of a dozen prominent roads in that part of the county which could conceivably fit the description of "Armstrong, Indiana" (as described by Rhatsa26WD). I then went to USPS.com and did ZIP searches for those roads, and the only ZIP codes that were returned were 47720 and 47725, not the 47617 listed in this paragraph. (By the way, the 47617 referenced in this article maps to HATFIELD IN, in an adjacent county.) Furthermore, the 47720 and 47725 that USPS.com returned do not map to a postal place name of ARMSTRONG IN but instead are EVANSVILLE IN postal addresses. Perhaps the mail is being delivered successfully to postal customers in Armstrong Twp addressed as "Armstrong, IN 47617", but successful delivery does not mean that the post-office name and ZIP code are correct as written.
In the case of the LaGrange example, the facts as presented are more or less correct (except "Lagrangeville," the postal place name, is not spelled with a mid-word capital G), but the situation is not all that unusual. It's an example that is matched in several states where the political boundaries of a "town" (or "township") do not correspond to a post-office name in its vicinity.

I suggest we consider deleting or radically scaling back on this section. It really isn't encyclopedic, when you come down to it. I think it is sufficient if we note that ZIP Codes were not meant to follow municipal lines, give a couple of examples, briefly, and let it go.-- Wehwalt ( talk) 17:48, 1 January 2008 (UTC)
The article currently states in an unsourced paragraph:
By the early 1960s a more general system was needed, and on July 1, 1963, non-mandatory ZIP codes were announced for the whole country. Robert Moon, an employee of the post office, is considered the father of the ZIP code. He submitted his proposal in 1944 while working as a postal inspector.
I just watched a classic episode of CBS's I've Got a Secret (a primetime nationwide U.S. show) and they had on one Bentley Hahn of Springfield, Virginia, whose secret was that he alone came up with the idea for the zip code. No other information was revealed about him, his role or his position at the postal servcie. There is a separate stub on Robert Moon with more about him inventing the zip code. Need I say there's an apparent contradiction here. Google searches are equally contradictory, with separate sources detailing each, separately, as the inventor of the zip code. In any event, the reference, should someone more familiar with this material wish to use it, would be <ref>Bentley Hahn appearance on [[CBS]]' ''[[I've Got a Secret]]'', November 6, 1963. Secret listed as inventor of the ZIP code. Rebroadcast on [[Game Show Network]] on March 4, 2008.</ref>-- Fuhghettaboutit ( talk) 01:44, 6 March 2008 (UTC)
Hi everbody, Do you think that this link: http://benfry.com/zipdecode/ would be suitable for this article? All the Best. Shane ( talk) 21:07, 19 May 2008 (UTC)
The trivia/in popular culture section is starting to get out of hand. There are millions of cultural/TV references to ZIP codes out there, and most of the ones that are mentioned are minor and irrelevant to the general topic. I propose that the list either be deleted or drastically reduced, and perhaps a prose section can be added on the significance of ZIP codes in TV and popular culture. -- TheCatalyst31 Reaction• Creation 22:58, 26 June 2008 (UTC)
I do NOT support total deletion of the list. A agree it could use a good pruning though. -- PopularData ( talk) 16:43, 29 June 2008 (UTC)
Section 2 under "By type/use" says: "There are four types of ZIP codes: Unique..., P.O.-box-only..., Military... and Standard..." but then the sub-section entitled "Non-standard examples" reads: "A few ZIP codes fall outside the three types..." . . . jg ( talk) 18:29, 8 July 2008 (UTC)
The page appears to have a rather serious formatting problem, or has been vandalised or corrupted somehow. Large chunks of text are unreadable and malformatted. — Preceding unsigned comment added by 87.194.150.228 ( talk) 22:32, 1 December 2008
Shouldn't we stop using acronyms as article titles and start using the terms in full. Like FIPS state code Redirects to Federal Information Processing Standard state code Mr Taz( talk) 16:14, 30 November 2008 (UTC)
Does anyone know what percent of zip codes are actually in use? In theory this would not be difficult if one had an exhaustive list of ZIP codes, but I do not know whether such a list exists in a form easily readable by computer. RSido ( talk) 04:49, 3 November 2009 (UTC)
I am looking for the area of the average zipcode, but could not find it on this page. 199.106.103.248 ( talk) 02:22, 12 December 2009 (UTC)
Small correction needed: "Use Zip code" (sic) labels were also used to promote the use of a ZIP code. — Preceding unsigned comment added by JohnXCitizen ( talk • contribs) 06:29, 29 May 2010
