Note that ZIP Codes are not ″boundaries,″ which is extremely essential to understand.They’re a collection of delivery routes that have been compiled.They do not adhere to physical or administrative boundaries, and they are capable of crossing city, county, and even state boundaries.They travel in the same direction as the delivery vehicles.Some ZIP Codes are considered to be outliers.One type of ZIP Code is designated as ″military,″ and it includes anything from military sites (local and international) to battleships at sea.

Then there are ZIP Codes that are ″unique.″ Because of the large volume of mail that businesses and organizations send and receive, they may be assigned their own ZIP Codes.These organizations regularly take advantage of bulk mailing reductions because they typically have a mail department that (1) presorts mail before delivering it to the USPS and (2) distributes mail internally so that the USPS is not required to do so.″Military″ and ″unique″ ZIP Codes are similar to ordinary ZIP Codes in that they circumscribe their own delivery region.Visit our ZIP Codes page for a more in-depth look at the system.

  • One of the most common mistakes people make when writing down an address has to do with the zip code — specifically, the four additional zip code numbers that are frequently present at the end of the address.
  • The possibility exists that you have seen them while getting an automatic-addressed item, or that you have seen this zip code as an option when purchasing anything online.
  • In other words, what precisely is the issue with all of those additional zip code designations?
  • We’ve got the answers you’re looking for.

What the traditional zip code means

  • When someone inquires about your zip code, you are likely to respond with a string of five numbers in response.
  • This is the standard practice for the vast majority of individuals, and it has been the standard practice for the United States Postal Service (USPS) from its inception.
  • When zip codes were initially established in 1963, they were part of a larger effort to improve the efficiency of mail delivery in the United States by dividing the country into zones based on mail routes.
  • The majority of the time, your five-digit zip code identifies the location of the post office where your mail is delivered before being delivered to you by your postal carrier.
  • Specifically, each digit in a zip code refers to a specific piece of information about the location being searched for.
  • The first number, which ranges from 0 to 9, designates a geographic region of the United States.
  1. The second and third numbers of a zip code designate a specific region within a geographic area, while the final two numbers are intended to designate a specific Post Office within that region.
  2. Some post offices serve more than one zip code, but for the most part, there is a one-to-one correspondence between post offices and zip codes in the United States.
  3. This is why the United States Postal Service frequently requires you to transact business with them at a certain location.
  4. Fun fact: Zip codes are assigned based on geographic location; codes begin at 0 in the east and progress towards 9 on the west coast as you go across the United States from east to west.

What the extra four numbers mean

  • Those extra four digits in your zip code were added more than two decades after the first zip code was established.
  • Due to the expansion of the United States’ infrastructure, the five-digit zip code system had to be updated with something more exact.
  • In 1983, a technique was developed to allow for more exact location of structures.
  • Now, you may identify certain streets, buildings, residences, or companies by using a regular zip code in conjunction with the four additional zip code digits available.

How important are the four extra zip code numbers?

  • For the majority of applications, the regular five-digit zip code will sufficient, and the full nine-digit zip code will not be required.
  • There are several exceptions to this rule, though.
  • There are several firms that are qualified to obtain a discounted bulk mailing rate.
  • This mail is handled in a different manner than ordinary delivery mail, and it frequently takes a little longer to reach its destination.
  • However, for many companies, the reduction is well worth it.
  • For mail delivered at a discounted bulk rate, the United States Postal Service requires a complete nine-digit zip code.
  1. An additional instance in which you may want your whole nine-digit zip code is when looking for your congressional representatives based on your address.
  2. In certain districts, knowing your whole zip code is the only method to identify the individual government officials that represent you.
  3. However, knowing your whole zip code will increase the likelihood of your mail being delivered correctly more frequently.
  4. The majority of mail will arrive at its destination without a hitch if you only enter your usual five-digit zip code, but if you’re concerned about a box not arriving, defining the intended location even further will not affect your chances of receiving your product.

Comments

  • Most applications do not necessitate knowing the whole nine-digit zip code; instead they can rely on the basic five-digit zip code.
  • The rule does not apply in all situations.
  • Businesses that send large volumes of mail are eligible to earn a discounted bulk mail rate.
  • It is common for this mail to take a little longer to reach at its destination since it is sorted separately from general-delivery mail.
  • Many firms, however, find that the savings is worthwhile.
  • For mail delivered at a cheaper bulk rate, the USPS requires a complete nine-digit zip code.
  1. Another instance in which you might need to know your complete nine-digit zip code is when looking for your congressional members based on your address..
  2. Identifying your individual government officials in certain districts is impossible without knowing your whole zip code.
  3. However, knowing your whole zip code can help to guarantee that your mail is delivered appropriately on a regular basis.
  4. If you merely provide your usual five-digit zip code, most mail will arrive at its destination without a hitch.
  5. However, if you’re concerned about a package not arriving at its destination, defining the intended location even further won’t hinder your chances of receiving it.

3 Different Ways to Style ‘ZIP Code’ (or Is That ‘ZIP code’ or ‘zip code’?)

  • The Quick and Dirty Guide to If you follow a specific style guide, double-check to see how it advises you write ″ZIP code,″ because each one appears to have a different guideline on how to write it.
  • The following is advice from three main style guidelines.
  • Today, we’ll start with the guidelines and conclude with a big dose of history since what I thought would be a simple query turned out to be a fascinating rabbit hole that led me to the point of interview.
  • It all started with a voicemail message from a friend.
  • ″Hello there, Grammar Girl.
  • It so happens that I work for the Federal Government and have such a strong command of writing and grammar that I am affectionately known as the Grammar Guru.
  1. While working on a report, something came up that needed to be addressed.
  2. It was suggested by some on the committee that the term ″ZIP Code″ should be capitalized…
  3. and my response is that this would be correct if you are referring to the particular item in question, such as a postal code or some other specific system, but if you are talking about the term ″zip code,″ it has become somewhat generic, similar to the term ″kleenex.″ If you chose to use this, I would appreciate it if you could answer it in your column, as I do not listen to your podcast.
  4. Thank you for your assistance, Grammar Girl.
  5. I will continue to be a loyal reader.
  6. Once again, thank you.

Good-bye, and thank you.″ Well, first and foremost, you should listen to the podcast, but the answer will also be available on the internet as a blog post.It is highly uncommon that the same piece of material does not appear on both sides.However, thank you for sending in your question as a voicemail, which I will be able to utilize in the podcast!For the same reason as before, I figured this would be a simple response: I’d check it up in a couple of style guides and wham, there’s the answer.However, it wasn’t as straightforward as that, and I soon discovered some fascinating nuggets.

What Are ZIP Codes?

  • ZIP codes are a uniquely American phenomenon, as our international readers will attest.
  • A postal address’s five-digit code may be found at the very end of the address’s body text (and if you want to be really detailed, you can add four more numbers to the end, and in my experience, doing that does help the post office deliver your mail a little faster).
  • The address codes are sometimes referred to as ″postal codes″ in other nations, and some countries do not have them at all.
  • The United States uses just numbers, although some other nations additionally use letters to denote time.
  • Because our caller works for the United States government, and ZIP codes are something that the government does, I looked up the style guide for the United States Printing Office first.
  • ″ZIP Code″ is the recommendation.
  1. The Associated Press style is similar: ″ZIP code″—two words with the letters ″ZIP″ in all caps—but it uses a lowercase C, which shocked me because I expected it to use a capital C.
  2. I dug a little more and discovered this, which made me laugh: Someone inquired in the AP Stylebook’s Q&A section as to why the term ″code″ is lowercased yet the source, the United States Postal Service, capitalizes it, and the response from the AP editors was as follows: ″The United States Postal Service prefers capitalisation over lowercase letters.
  3. We each have our own own style.″ So there you have it!
  4. It’s simply that they like it in lowercase.
  5. That is how styles function.

‘ZIP Code’ Was Trademarked

  • I had no idea that ″ZIP″ stood for ″Zone Improvement Plan″ and that the United States Postal Service was the first to trademark the word ″ZIP Code.″ According to the information on the US Patent and Trademark Office website, the trademark was registered in 1997 and then lapsed in 1997.
  • A ″TM″ is still there after ″ZIP Code″ on the United States Postal Service website, on the other hand.
  • So it’s possible that I overlooked something, or that whomever is in charge of maintaining their website didn’t get the memo.
  • Even while the Associated Press Stylebook does not include a trademark sign after ″ZIP code,″ it does not advocate that it be done for any trademark, therefore this does not provide any information about the trademark’s status.
  • It was also revealed to me that the home furnishing firm Wayfair has a trademark for the use of the phrase ″zipcode″ (which is a single word) on things such as lamps, rugs and bedding, as well as on furniture.
  • What a bizarre situation.
  1. So I went to the website to see if they had any things that had the phrase ″zipcode″ on them, but they didn’t have anything like that.
  2. In its place, they have something that appears to be a house brand, dubbed Zipcode Design.
  3. As a result, it makes more sense.

Check 3 Style Guides and Find 3 Different Ways to Write ‘ZIP Code’ 

  • Not only did I not realize that ″ZIP″ stood for ″Zone Improvement Plan,″ but I also didn’t realize that the US Postal Service was the first to trademark the term ″ZIP Code.″ In my research, I discovered that the trademark in question had expired in 1997, according to the website of the United States Patent and Trademark Office.
  • A ″TM″ is still present after ″ZIP Code″ on the United States Postal Service website, on the contrary.
  • So it’s possible that I overlooked something, or that whomever is in charge of maintaining their website didn’t get the memo.
  • Regardless, In this case, the AP Stylebook does not include a trademark sign after ″ZIP code,″ but it does not encourage doing so for any trademark, so we cannot infer anything about the trademark’s status from this practice.
  • I also discovered that the home furnishing firm Wayfair has the trademark for the use of the phrase ″zipcode″ (which is spelled out as a single word) on things such as lamps, rugs, beds, and furniture, among others.
  • Isn’t that bizarre?
  1. Consequently, I scanned the website to see whether they had any items that had the phrase ″zipcode,″ but they did not.
  2. In place of it, they have something that appears to be a house brand, named Zipcode Design, As a result, it is more logical.

‘Zip-code’ Is a Verb

You might have thought we were done, but ″zip-code″ can also be used as a verb! In both Dictionary.com and Merriam-Webster, ″zip-code″ is listed as a verb, and both sites preserve the word in all lowercase and without the hyphen. When something is zip-coded, it indicates that it has been marked with a ZIP code, as in ″Be careful to zip-code that letter.″

The History of ZIP Codes

  • ZIP codes are considerably more recent inventions than I had anticipated.
  • The basic 5-digit codes that we use in the United States today were just adopted in 1963, and at the time, they were purely optional for consumers.
  • There are probably still some individuals who do not have an address, and it was then that I realized I knew someone who was quite knowledgeable about the history of addresses and could tell me a lot of interesting facts about them.
  • ″The Address Book: What Street Addresses Reveal about Identity, Race, Wealth, and Power,″ written by Deirdre Mask, is available for purchase on Amazon now.
