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)[reply]
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)[reply]
There is no such thing as a ZIP+6, just a ZIP+4. You are referring to the Intelligent Mail barcode instead, but individuals would never write out the extra two digits on their own and its not technically part of the ZIP code.--2601:642:C301:119A:9DF5:701B:DAFA:9F10 (talk) 01:08, 14 June 2018 (UTC)[reply]
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.

Postal zones in big cities are seen in advertisements from 1920[edit]
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)[reply]
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)[reply]
The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.
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"[1]. 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)[reply]
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)[reply]
Essentially neutral, leaning support now. (Willing to go with consensus, cheers) — Andy W.(talk ·ctb) 15:32, 15 August 2016 (UTC)[reply]
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. Nyttend (talk) 03:21, 14 August 2016 (UTC)[reply]
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)[reply]
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)[reply]
Support - Based off use in the GPO PDF linked above. Meatsgains (talk) 02:22, 19 August 2016 (UTC)[reply]

Influence of Time Warner on introduction of Zip codes?[edit]
The page ZIP Code says nothing about the influence of Time Warner. Can somebody help to clarify this!? Thanks! — Preceding unsigned comment added by 78.54.130.124 (talk) 11:46, 28 November 2017 (UTC)[reply]
I have just modified 3 external links on ZIP Code. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
Readded to the main talk. It's not clear why that was archived (to the incorrect archive) while things six years older remained here. Dekimasuよ! 18:10, 11 March 2018 (UTC)[reply]
Indeed, Wikipedia should reflect the common usage, not try to impose an arguably more correct usage. fgnievinski (talk) 18:14, 6 July 2023 (UTC)[reply]

ZIP Code → zip code – Lower case it per MOS:CAPS - that previous RM had mainly dubious rationales, per MOS:CAPS, capitilization should only be used when the terms are consistently capitilized, ngrams reveal a very mixed usage with "zip code" not only being the most common, but also preferred by MOS as least amount of capitilization. Or at the very least it should go to "ZIP code" and not "ZIP Code". Galobtter (pingó mió) 13:15, 11 March 2018 (UTC)[reply]
Using the plural ngrams it is even clearer that the dominant style is lower cased, with second being "ZIP code" Galobtter (pingó mió) 13:15, 11 March 2018 (UTC)[reply]
Oppose per MOS:TMRULES. "Capitalize trademarks, being proper names." "Capitalize IKEA, IBM, as acronyms/initialisms," which ZIP is. Largoplazo (talk) 13:37, 11 March 2018 (UTC)[reply]
I'd argue that it is now more of a common word. It's relatively rare for it to be styled as "ZIP Code" so I'd say it should atleast be to "ZIP code" Galobtter (pingó mió) 17:01, 11 March 2018 (UTC)[reply]
I appreciate your point. However, normally when one speaks of a trademark becoming a common term, it's a matter of making it generic, using it to refer to any instance of a class of things of which the trademark is only one brand. Examples: "kleenex" to denote any facial tissue, not just Kleenex brand, or "jello" to denote any flavored dessert gelatin, not just Jell-O brand (and, on the other hand, not to refer to any Jell-O brand products, such as puddings, that aren't flavored dessert gelatins). Uses of "zip code" still generally refer to the U.S. ZIP Code, rather than representing a genericization covering postal code worldwide. Or, let's flip that: if people are using "zip code" generically to denote postal codes, well, this is not the article about postal codes generally. It's about the specific postal code system branded as ZIP Code.
Further, the idea of "zip code" becoming generic vanishes as soon as one steps outside the United States. Anywhere else in the English-speaking world, I imagine that people think of U.S. postal codes just as they think of Canadian postal code and Australian postal codes. They may have no idea that we have a trademark for ours. And those who are aware of the trademark, I would expect a priori, would be fully aware of its status as such, and would expect the capitalization. Largoplazo (talk) 17:44, 11 March 2018 (UTC)[reply]
Oppose move - article is properly titled as is per WP:COMMONNAME and the acronym ZIP should remain all caps per MOS:CAPSACRS.--John Cline (talk) 17:57, 11 March 2018 (UTC)[reply]
Oppose for the reasons stated above. It is clearly a trademark and should be titled as trademarked. It's like how many people in the 1970s, 1980s, and 1990s informally referred to "xeroxing," but the correct trademark is always Xerox and the correct verb is photocopying. --Coolcaesar (talk) 18:56, 11 March 2018 (UTC)[reply]
Oppose per above. However, maybe further discussion should be had on whether it's "ZIP Code" or "ZIP code". Paintspot Infez (talk) 12:09, 12 March 2018 (UTC)[reply]
We have discussed that and are discussing that, so feel free to join in. Largoplazo (talk) 12:10, 12 March 2018 (UTC)[reply]
Partial support It's not clear to me whether "ZIP" is sufficiently widely used as a generic term to be lower-cased, although the Google ngrams are interesting and a Google search for "ZIP code" shows many uses of the term for postal codes outside the US, but "code" is a common noun and there's no reason to capitalize it in this context. Peter coxhead (talk) 12:19, 12 March 2018 (UTC)[reply]
ZIP Code is a proper name of itself, and capitalized therefor. The quality sources I noticed give it this way as well.--John Cline (talk) 13:20, 12 March 2018 (UTC)[reply]
Oppose. The USPS, which manages them, calls them ZIP Codes. To comply with WP:NOR, we should either call them what the USPS calls them or have a good, sourced reason why not. Doctor Whom (talk) 15:25, 12 March 2018 (UTC)[reply]
Oppose Per Doctor Whom. ZXCVBNM (TALK) 03:52, 13 March 2018 (UTC)[reply]
Oppose:USPS's trademarked name is per the article name so there is no reason to vary that usage. At the very most it might be renamed "ZIP code" per some sources but certainly not lowercase. ww2censor (talk) 14:31, 13 March 2018 (UTC)[reply]
