I see from edit history that we at one point had a section listing service codes but that it was removed for copyright reasons. Do we have some sort of non-/less-proprietary source for even a subset of such a list that could be included as examples? -- 50.121.72.28 ( talk) 16:09, 3 December 2018 (UTC) reply

• I'm not sure that would be useful in an encyclopedic article considering how often the service codes change. The second reference on this article will take you to a CenturyLink document that has a few codes listed. That's about the best I can think of, but even that is likely to be copyrighted material. — TadgStirkland⁴⁰¹ (Tadg^Talk) 16:27, 4 December 2018 (UTC) reply
