How Full ZIP Codes Are Used

Knowing what the last four digits of a ZIP Code are all about necessitates a thorough understanding of what ZIP Codes are in general terms.The Zone Improvement Plan was developed by the United States Postal Service in order to make it simpler to send mail and parcels around the country.Due to the way mail was dispersed, it helped split the country into distinct ″zones,″ which aided in speeding up the sorting and delivery process.

During the same time period that the Postal Service Department announced the Zone Improvement Plan on July 1, 1963, they also presented the world to Mr.ZIP ″Zippy,″ a fictional character created by the Postal Service.Zippy is the official ZIP Code mascot, and he can be found on our ZIP Codes 101 website as well.They also produced the ZIP Code jingle, which goes as follows: The audio element cannot be played because your browser does not support it.Since 1963, as the population of the United States has grown and dispersed, it has become necessary to extend the system in order to accommodate everyone and their canine companion.That’s where the ″plus 4″ portion of the equation comes in.

However, we’re getting ahead of ourselves, so let’s start with the fundamentals.

USPS Five-Digit ZIP Codes

These are the codes with which you are already familiar.They have the following appearance……and are most usually used to denote a destination post office.The reason behind this is as follows: If you’re shipping a letter from Boston to Seattle, the Massachusetts postal carrier isn’t really concerned with the street address of the recipient’s residence.

What you may label ″beyond his jurisdiction″ is the situation.He only has to know which postal carrier to use in order for the other carrier to deliver the package to the correct address.On any given day, a postal worker can only cover a certain amount of ground.And because the United States Postal Service has a policy of delivering in all weather conditions, including rain, sleet, and snow, there is no way to provide the service of delivering in stages (some today, some tomorrow).In other words, each one post office can only service the area that it can reach in a single day.That is reflected in the ZIP Codes.

The majority of the time, a ZIP Code is associated with a post office; that is, every one of the latter has a corresponding one of the former.ZIP Codes may be thought of as a sort of postal address for a certain post office location.Some agents cover more than one ZIP code, but the majority of them operate on a one-on-one basis.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.

  1. They travel in the same direction as the delivery vehicles.
  2. Some ZIP Codes are considered to be outliers.
  3. One type of ZIP Code is designated as ″military,″ and it includes anything from military sites (local and international) to battleships at sea.
  4. 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.
  5. 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.
  1. ″Military″ and ″unique″ ZIP Codes are similar to ordinary ZIP Codes in that they circumscribe their own delivery region.
  2. Visit our ZIP Codes page for a more in-depth look at the system.

  2. Only a PO Box (for example, 22313 for the PO Boxes in Alexandria, Virginia)
  3. Armed forces
  4. standard (all of the other ZIP codes)

Assignment of ZIP codes and Mail Sorting

The first number of a ZIP code in the United States often denotes a group of states in the United States.The map of the first digit of zip codes shown above illustrates that they are assigned in the sequence shown above, starting with the north east and working our way west.The first three digits of a ZIP code are used to establish the location of the central mail processing facility, also known as a sectional center facility or ″sec center,″ which is responsible for sorting and processing mail.

All mail containing the same first three digits is sent to the same second center, where it is sorted according to the last two digits and dispersed to local post offices in the same order.The sec centers are not available to the general population and perform the majority of their sorting at night.As you can see from the map of the first three digits of zip codes, the digits following the first are also frequently allocated from east to west, as can be seen in the table of the first three digits of zip codes.The number 0 is closer to white on the map, while the number 9 is considerably more vibrant.Despite the fact that there are a few outliers, it is simple to follow the gradient across each of the zones (such as the southwest tip of Georgia which uses 39XXX like central Mississippi).Although the ZIP+4 code is not essential, it does assist the post office in sorting mail in an extra manner.

A ZIP+4 code may equate to a city block, a group of residences, or a single high-volume receiver, depending on the situation.Every PO Box number corresponds to a distinct ZIP+4 code, which is another prevalent practice.Multiple PO Box numbers are often combined into the same ZIP+4 code by utilizing the last few digits of the PO Box number.This is known as grouping.However, because this procedure is not a general norm, the ZIP+4 code must still be sought up for each individual PO Box.

Places in the US so Remote, They Don’t Have a ZIP

As you can see from the map, ZIP codes are not issued to every location in the United States.There are not enough deliverable addresses in remote and particularly rural sections of the nation to support the creation of a mail route.A ZIP code is not required if there is no postal delivery.

In terms of getting away from civilization, these locations are some of the most isolated spots in the whole country if you choose to do so.

USA ZIP Code Boundaries

Despite the fact that ZIP codes appear to be of a geographical character, this was not their original use.They are meant to consolidate mail in order to help the United States Postal Service to carry mail more effectively.It is common for ZIP codes to span numerous states in order to improve the efficiency of mail routing and delivery.

In the majority of situations, addresses that are in close proximity to one another are put together in the same ZIP code, giving the impression that ZIP codes are defined by a distinct geographic border.Some ZIP codes, on the other hand, have nothing to do with geographical places.For example, the United States Navy uses a single ZIP code for all of its mail.When ZIP codes appear to be spatially clustered, a distinct contour surrounding the ZIP code cannot always be drawn since ZIP codes are only given to a point of delivery and not the intervals between delivery locations.It is possible that ZIP codes may not be set or that their borders will be unclear in regions where there is no regular postal route or no mail service.

US ZIP Code Map

According to the most recent USPS data, there is no official ZIP code map.The primary problem has already been discussed: there isn’t always a clearly defined geographic limit for a ZIP code.No official or completely accurate map of a ZIP code can be produced by the Census Bureau or other commercial services, but many of them will attempt to interpolate data to construct polygons (shapes formed by straight lines) to show the approximate region covered by a ZIP code.

All ZIP code maps on this site are based on the ZIP Code Tabulation Areas (ZCTAs) defined by the United States Census Bureau in 2010 (or later) and explained in greater detail further down this page.They offer an extremely accurate representation of the geographic region covered by a ZIP code.When you look at our maps, you will quickly see that there are some border concerns.When a ZIP code is not assigned to a location (as is the case in much of Nevada and Utah), it is because there are few, if any, addresses to which the mail may be delivered.It is important to note that if an address is located on the same street as a ZIP code border on a map, you should search for the entire street address to ascertain the ZIP code rather than depending on the map.

ZIP Code Tabulation Areas (ZCTAs)

The United States Census Bureau created the tabulation regions for ZIP code numbers in the 1950s.Their objective is to provide statistical information on geographical areas that are recognizable to the majority of residents.ZCTAs, on the other hand, are not precisely the same as ZIP codes.

Because of the difficulties in exactly defining the geographic region encompassed by a ZIP code, as previously stated.To account for some of the problems associated with assigning a geographic area to a ZIP code, ZCTAs were created in order to more accurately identify a geographical region.ZCTAs are also not updated on a regular basis like ZIP codes are.In general, they are updated once every ten years in order to coincide with the United States Census.The Census allocates an area to a ZCTA based on the number of census blocks in the area (the smallest geographic unit used by the census).Consider the image on the right, which depicts a city block that corresponds to a normal census block.

All four sides are bordered by sections of city streets, each with its own name and address, which surround the entire area.The problem is that census blocks are usually often divided down the center of the street, which is problematic.ZIP codes seldom do this since it would necessitate two postal workers carrying mail to that street – one for each side of the street – which would be prohibitively expensive.A postal carrier may deliver to three sides of the block using one ZIP code in this example, while another mail carrier may deliver to the other street using a different ZIP code.As a result, because the census block is the area that has been exactly measured, the Census Bureau will allocate the whole block to a single ZCTA (in this example, 21044).It is nearly always necessary to split ZIP codes when getting extremely exact (typically a matter of meters, not miles).

  1. Census block borders towards the boundary of a ZIP code almost always result in this situation.
  2. It is possible to get insight into the demographics of a ZIP code by using the information published by the Census Bureau.
  3. For example, have a look at our ZIP code rankings.

Matching ZIP Codes with States, Counties, and Cities

Keep in mind that ZIP codes were created to make mail delivery more convenient.Their limits were not drawn in accordance with existing boundaries, such as those of cities, counties, or even states.Whenever it is more cost-effective for a mail carrier to drive over a state border to deliver mail, the ZIP code ″boundary″ will be extended across state boundaries.

ZIP codes often do not cross state boundaries, although there are several that do (65733, 71749, and 73949 are good examples).Our comprehensive list of ZIP codes that cross state boundaries is accessible as part of our comprehensive list of ZIP codes in the United States.If you’re trying to assign a ZIP code to a certain county (up to 25 percent of ZIP codes cross county boundaries), congressional district, metro region (with time zone and area code), or other specific location, things get much more difficult.The margins of the boundaries frequently overlap with one another.For the purposes of our free zip code database by county downloads, we will typically provide either the most frequent region for the ZIP code or numerous regions if more than one region exists in the ZIP code for the purposes of our free zip code database by county downloads.The assignment for cities is a little more difficult to figure out.

The United States Postal Service (USPS) does not always utilize the city in which the ZIP code is situated.The assignment of cities to ZIP codes is done on a more broad scale.The name of the city is typically the same as the name of the main post office.For example, practically all ZIP codes in St.Louis County, Missouri, are labeled as being in the city of Saint Louis, despite the fact that they are more appropriately defined as being in the name of a smaller city in which they are located.More information on matching ZIP codes to cities and counties may be found here.

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.While working on a report, something came up that needed to be addressed.It was suggested by some on the committee that the term ″ZIP Code″ should be capitalized…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.

Thank you for your assistance, Grammar Girl.I will continue to be a loyal reader.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!

  1. 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.
  2. 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 overseas 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.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.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.We each have our own own style.″ So there you have it!

It’s simply that they like it in lowercase.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.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.In its place, they have something that appears to be a house brand, dubbed Zipcode Design.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?Consequently, I scanned the website to see whether they had any items that had the phrase ″zipcode,″ but they did not.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.

Pin Code: Search & Find Postal Codes, Zip Codes & Pin Codes of India

In India, the phrase Postal Index Number, often known as PIN code, is extensively used to refer to the number assigned to a letter by the postal service.It refers to the code included in the post office number of the postal code system, which is primarily utilized by the Indian Postal Service to categorize and separate mailings from one another.The Postal Index Number is a string of six lengthy numbers that identify a specific address.

Shriram Bhikaji Velankar, who was then the additional secretary in the Union Ministry of Communications, was the first to establish this technique of coding the postal address, which was first implemented in 1972.When the PIN-code system was introduced in India, it was primarily intended to assist postal departmental staff in manually sorting and delivering mail to the correct address, thereby reducing confusion caused by similar place names, incorrect addresses, and different languages spoken by the general public.

Decoding the PIN Structure

  • The Postal Index Number, often known as the PIN, is made up of six lengthy numerical digits, each of which represents a different area. It is composed of the following digits: 1 identifies the zone
  • 2 denotes a sub-zone
  • 3 denotes a sorting district within a zone
  • 4 denotes an individual post office within a sorting district
  • and 5 denotes a single post office inside a zone.

From the Goodreturns Pin Code Finder, you may get your postal codes by selecting your state, district, and post office of your location from the drop-down menu.

Postal Zones in India

Indian postal zones are divided into nine divisions, eight of which are regional and one of which is dedicated solely to the Indian Army and is known as a functional zone. This is indicated by the first digit of the PIN number, which is allocated throughout the nine zones that are scattered over the length and width of the nation.

First Digit of PIN Code Zone
 1 Delhi, Punjab, Haryana, Jammu & Kashmir, Himachal Pradesh, Chandigarh
2 Uttarakhand, Uttar Pradesh
3 Gujarat, Rajasthan, Diu and Daman, Dadra and Nagar Haveli
4 Goa, Maharashtra, Madhya Pradesh, Chhattisgarh
5 Karnataka, Andhra Pradesh, Telangana
6 Kerala, Tamil Nadu, Lakshadweep, Puducherry
7 Odisha, West Bengal, Nagaland, Arunachal Pradesh, Manipur, Tripura, Mizoram, Meghalaya, Assam, Sikkim, Andaman & Nicobar Islands
8 Jharkhand, Bihar
9 Army Post Office (APO), Field Post Office (FPO)

Sorting Districts

This specific geographic region (with the exception of the functional zone that is designated for the Army) is represented by the third digit of the Postal Code Number combined with the first two digits, which are collectively referred to as a sorting district.The sorting district is headquartered at the main post office of the largest city in the region, and it is also referred to as a sorting office.Depending on the volume of mail processed in the region, each state may have one or more sorting districts, which are independent of one another.

PIN Prefix ISO 3166-2:IN REGION
11 DL Delhi
12 – 13 HR Haryana
14 – 15  PB Punjab
16 CH Chandigarh
17  HP Himachal Pradesh
 18 – 19 JK Jammu & Kashmir
