This article makes only passing reference to 11 digit ZIPs, whereas it concentrates a lot on ZIP+4. I'd like to see more information on ZIP11. I remember when it was first implemented, but I know very little about it. --Tim Sabin (talk) 16:08, 30 March 2010 (UTC)
I don't think there's anyone continually working on this article, you may want to do a little research yourself. Wikipedia will be the better for it.--Wehwalt (talk) 16:20, 30 March 2010 (UTC)
Second address format shows a proper ZIP Code address as: Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis, Minnesota 55416
The previous paragraph stated:
“Simultaneously with the introduction of the ZIP code, two-letter state abbreviations were introduced. These were to be written with both letters capitalized.”
Therefore, the proper address format with ZIP Code and two-letter state abbreviation should be:
Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis, MN 55416
Just a minor correction from a retired old postmaster. Paul L. Fletcher 1816 N. Moreland Ave. Indianapolis, IN 46222-4828 — Preceding unsigned comment added by 188.8.131.52 (talk) 22:23, 28 December 2011 (UTC)
Postal zones in big cities are seen in advertisements from 1920
As of this writing, the article states that postal zones in big cities (such as "Minneapolis 16") began in 1943. But I have been looking at journal and magazine advertisements from 1920, and have seen several examples of them. Here are two: Boston 9, Mass. and Boston 9, Mass.. Perhaps someone can look deeper into the history of these zone numbers. Possibly me, later, although not right now. — ¾-10 21:03, 10 February 2013 (UTC)
The requirement of the vast majority of US pay-at-the-pump, er, pumps, is a royal pain to visitors from Abroad who don't have a ZIP code. A gas station cashier in Mesquite NV told me that visitors can get a special ZIP code from their card's issuer, but I suspect that this may only apply to Canadians (she specifically mentioned "snowbirds") as no-one I asked back here in the UK, nor British ex-pats, had ever heard of such a thing. If Jane of Mesquite is correct then it could be worth a mention from someone who knows what they're talking about. Mr Larrington (talk) 16:25, 8 October 2014 (UTC)

ZIP code → ZIP Code – The other day, an editor capitalized "ZIP code" to "ZIP Code" throughout the article. Indeed, the whole thing is trademarked as "ZIP Code". Should the article be moved to ZIP Code, which has always been a redirect, and which currently redirects here? Largoplazo (talk) 23:43, 13 August 2016 (UTC)
Interesting. For a government-created term, the GPO manual is "official", but I don't know how strong a criterion that is for Wikipedia's decisions on capitalization. Largoplazo (talk) 00:23, 14 August 2016 (UTC)
Essentially neutral, leaning support now. (Willing to go with consensus, cheers) — Andy W.(talk ·ctb) 15:32, 15 August 2016 (UTC)
Move. "ZIP code" is an odd mix of capitalisation: use "zip code", as people often do casually, or "ZIP Code", for the official name. I prefer "ZIP Code" myself, because official terms are generally more solid, more encyclopedic, than informal usage, but either one is better than this mongrel usage.

Move: based on my reading of trademark rules and the one example of a multi-word name, Cadbury Creme Egg, title capitalisation seems the correct way to go. If the word "code" were descriptive of the product and not an integral part of the name, as a non-proper noun, I would vote for it to remain as it is. ww2censor (talk) 12:02, 14 August 2016 (UTC)
Move: ZIP Code is a proper name and should be capitalized. Postal code is the generic term. Concept14 (talk) 03:10, 17 August 2016 (UTC)
Support - Based off use in the GPO PDF linked above. Meatsgains (talk) 02:22, 19 August 2016 (UTC)
