About US ZIP Codes

  • Share:
  • E-MAIL
  • US ZIP codes are a form of postal code that is used in the United States to aid in the efficient routing of mail by the United States Postal Service (USPS) and other organizations.
  • On the map above, you can see ZIP codes that are close to me.
  • ZIP codes are still referred to as ″US postal codes″ by certain people.
  • ZIP is an acronym that stands for Zone Improvement Plan.
  • A ZIP+4 code is formed by adding an additional four digits after a dash after the first five digits of the basic format, which was originally adopted in 1963.

The additional four digits allow the United States Postal Service to more accurately categorize mail for delivery.ZIP codes were initially designed for the United States Postal Service (USPS), but they are now used by many other shipping firms, including the United Parcel Service (UPS), Federal Express (FedEx), DHL, and others, for sorting parcels and estimating the time and cost of transporting a product (the shipping rate).

Types of Zip Codes

  1. A single high-volume address that is unique (for example, 20505 for the CIA in Washington, DC)
  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 CIA’s Washington, DC headquarters has a unique/single high-volume address (for example, 20505).
The address must be a PO Box exclusively (for example, 22313 for the Alexandria PO Boxes);
Military; Standard (all other ZIP codes); and Specialized.

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.
  1. All four sides are bordered by sections of city streets, each with its own name and address, which surround the entire area.
  2. The problem is that census blocks are usually often divided down the center of the street, which is problematic.
  3. 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).
  • Census block borders towards the boundary of a ZIP code almost always result in this situation.
  • It is possible to get insight into the demographics of a ZIP code by using the information published by the Census Bureau.
  • 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.
  1. The United States Postal Service (USPS) does not always utilize the city in which the ZIP code is situated.
  2. The assignment of cities to ZIP codes is done on a more broad scale.
  3. 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.

Why do we use zip codes?

It was on July 1, 1963, that the United States Postal Service (USPS) instituted the practice of utilizing ZIP codes as a whole.Prior to that, beginning in 1943, the United States Postal Service operated a set of postal zones that were restricted to big cities only.This number would appear after the city and before the state in an address, and postal carriers would utilize it to sort mail more effectively if you were writing an address.Look back 100 years to see what postal delivery looked like.

What does each number in a zip code mean?

In 1944, a postal worker by the name of Robert Moon presented a suggestion for a new postal zone system that would be applicable throughout the whole nation.The first number would represent a group of states, with zero representing the east coast and nine representing the west coast, and the second and third numbers would specify to which sectional center facility (the location where mail is processed and distributed) the mail should be delivered in that area.It wasn’t until after World War II that the United States Postal Service finally implemented this concept, adding two numbers at the end to identify the correct post office or postal zone, giving birth to what is now called a Zone Improvement Plan Code (also known as a ZIP code).Take a look at some other amazing facts about the United States.Postal service.

What do the four numbers at the end of a zip code mean?

A little more than two decades after the initial ZIP codes were established, the United States Postal Service added one additional modification to the system: the four digits that appear after the ZIP code.These denote a specific geographic area that a certain post office serves.When the sixth and seventh digits are used, they relate to a delivery sector, which might be a collection of streets, a single huge structure, or another limited geographic region.The final two letters denote a delivery segment, such as a floor of an office building or one side of a roadway.However, even though the United States Postal Service claims that the ZIP code was created by a committee of individuals, our addresses would look quite different if it weren’t for Moon’s numerical inspiration.

What is a ZIP Code and how do they work?

Postal ZIP Codes (ZIP Codes) are five-digit identifiers created by the United States Postal Service to identify particular post offices throughout the United States.A ZIP Code is just the abbreviation for the postal code system used in the United States of America.Most nations, including the United States, have their own names for their postal code systems.For example, the Indian government refers to its system as ″Postal Index Numbers.″ Postal Routing Numbers are what the Czech Republic refers to as their system.As a result, when you hear the term ″ZIP Code,″ think ″United States.″ The 5-digit ZIP Code is divided into three parts: the national area, the region or city, and the delivery area.

  • The national area is the first component of the ZIP Code, followed by the region or city and the delivery area.
  • The United States Postal Service (USPS) has divided the country into ten ZIP Code zones, each with its own post office.
  • They are numbered 0-9.
  • They begin in the northeast and work their way west.
  1. The region covered by each ZIP Code is depicted on the map below: The following is how the first digit of the ZIP Code is assigned:
ZIP Codes Beginning With States
0 Connecticut, Massachusetts, Maine, New Hampshire, New Jersey, Puerto Rico, Rhode Island, Vermont, Virgin Islands, Army Post Office Europe, Fleet Post Office Europe

9 Alaska, American Samoa, California, Guam, Hawaii, Marshall Islands, Federated States of Micronesia, Northern Mariana Islands, Oregon, Palau, Washington, Army Post Office Pacific, Fleet Post Office Pacific

How to Read a ZIP Code

Following the assignment of the first number in a ZIP Code, the United States Postal Service (USPS) assigns the next two digits based on the location of the city.If an area has a major town or city, the United States Postal Service (USPS) would frequently award it the first ZIP Codes.Following that, the ZIP Codes will be shown in alphabetical order.The first three digits of a ZIP Code, when added together, often indicate the sectional center facility to which that ZIP Code belongs, according to most sources.This facility serves as the mail sorting and distribution hub for a certain zone or geographic area or region.

  • Some divisional center facilities have numerous three-digit codes given to them, which makes it difficult to locate them.
  • For example, the Northern Virginia sectional center facility in Merrifield is issued ZIP Codes that begin with the numbers 220, 221, 222, and 223 to distinguish it from other similar facilities.
  • The fourth and fifth digits of the ZIP Code show the geographical location of the city or municipality.
  • For example, if a letter is received with a ZIP Code of 47722, the United States Postal Service (USPS) can determine that it is in Indiana (4), Vanderburgh county (77), and the region around the University of Evansville (22)

ZIP Codes are Lines, Not Shapes

  • ZIP Codes are not assigned based on geographic boundaries such as state borders. In truth, because ZIP Codes are intended only for the purpose of increasing postal efficiency, they may and do transcend county and state lines. As an illustration: 42223 encompasses Christian County, Kentucky, and Montgomery County, Tennessee
  • 97635 contains sections of Lake County, Oregon, and Modoc County, California
  • 51023 and 51001 are located in both Iowa and Nebraska
  • and 42223 spans Christian County, Kentucky, and Montgomery County, Tennessee.

ZIP Codes do not represent physical areas; instead, they identify address groupings or delivery routes.Although most ZIP Codes may be loosely allocated to a geographic location, ZIP Codes do not represent geographic regions.As a result, ZIP Code ″areas″ might overlap with one another, be included within another ZIP Code, or have no geographical boundaries at all.For example, ZIP Codes that begin with 095 are issued to the Navy and do not correspond to a specific geographic place as a result.Similarly, ZIP Codes are not allocated to locations that do not have regular postal routes (rural route regions) or areas that do not get mail delivery (undeveloped areas).

  • Because they are based on few delivery routes, the boundary between ZIP Code zones is indeterminate in certain places.
  • See our guidelines on how to locate a county by ZIP Code for further information.
  • Whenever a ZIP Code crosses across a county boundary, Smarty (previously SmartyStreets) displays the default county in the line called ‘County Name’ and includes an additional line named ‘Alternate Counties’ in the table.

ZIP+4 Codes

The United States Postal Service (USPS) modified its ZIP Code system in 1983 to incorporate the new ZIP+4.A ZIP+4 Code is made up of the original five-digit code plus four more digits, resulting in a complete nine-digit postal code.With the whole ZIP Code, you may identify any tiny delivery segment, such as a street, a city block, a group of flats, or even a single address, which gets a large amount of mail.Using a ZIP+4 Code is not essential, as it is often computed automatically during the sorting and processing of the mail.ZIP+4 Codes are formatted as follows: As a general rule, each Post Office Box is assigned a unique ZIP+4 code.

  • With a +4 on the ZIP Code, the last four digits of the box number are frequently used, as is zero plus the final three digits of the box number, or if the box number is less than four digit, zeros followed by the box number.
  • Because of this variation, the ZIP+4 Code for each Post Office Box must be searched up individually.
  • Not all USPS deliverable addresses have a ZIP+4 code allocated to them, despite the fact that the majority of them do.
  • For some addresses, geocoding lookups or address validation that need a ZIP+4 may not be successful, depending on the address type.
  1. While the United States Postal Service may not be able to offer correct geocodes for such addresses, Smarty can still provide roof-top level geocodes for the majority of addresses in the United States.
  2. By experimenting with the Smarty US ZIP Code API or reading our ZIP Code API documentation, you can discover further possibilities.

Why ZIP codes have 5 numbers — and what they each mean

On Wednesday, the United States will celebrate the 52nd anniversary of the adoption of ZIP codes.The Zoning Improvement Plan (ZIP) was conceived during World War II, when the first two numbers were adopted, despite the fact that the proliferation of business mail is primarily responsible for the plan’s inception.When thousands of postal employees went to join in the military during World War II, the system was left understaffed and in desperate need of simplification.The first zoning address system was implemented in 1943, and it has been in use ever since.To begin, 124 of the major cities in the United States were assigned two numbers, the first identifying the city and the second indicating the state.

  • The numbers were designed to make sorting easier for personnel who were less familiar with the system.
  • As the amount of mail increased, the postal system added the three more numbers 20 years later, in 1963.

What each number means

  • The first numeral denotes a broad area, ranging from zero in the Northeast to nine in the extreme West
  • the second digit designates a specific area
  • and the third digit designates a specific area.
  • Following that are the two numbers that represent the code for a central post office facility in that region
  • A tiny post office or postal zone is designated by the final two digits of the postal code.

The first ″1″ in a 10014 ZIP code represents Delaware, New York and Pennsylvania; the second ″00″ represents New York Sectional Center Facility; and the third ″14″ represents the portion of Manhattan that is within the ZIP code (Meatpacking and the West Village).Six months after the introduction of ZIP codes in the United States in 1963, every address in the country had been allocated a code.

Additional numbers

Several ZIP codes were updated in 1983, with the addition of a hyphen and a four-digit number.Because mail could no longer be separated into categories using simply standard ZIP codes, the ZIP+4 code was introduced.However, it never gained widespread acceptance.The development of sorting technology shortly after it was used rendered it mostly ineffective and obsolete.When you see the sixth and seventh digits, you know you’re in a ″delivery sector,″ which might be anything from an office building to a tiny geographical region to a few blocks to a major apartment building.

  • The following two digits denote a delivery segment, which might be as particular as a specific floor of an office building or as broad as an entire department within a corporation.
  • Despite the fact that technological advancements in recent decades have significantly reduced the volume of snail mail received, ZIP codes are still widely utilized for a variety of purposes.
  • With the use of ZIP codes, it is possible to acquire a plethora of information about the people who live in a certain location.
  • This information includes things like age, education level, gender, and race.

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.
  1. Thank you for your assistance, Grammar Girl.
  2. I will continue to be a loyal reader.
  3. 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 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!
  1. It’s simply that they like it in lowercase.
  2. 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’ 

There are three alternative ways to write ″ZIP code″ according to the three style standards I researched. The ″ZIP Code″ is used by the United States Government Publishing Office. The Associated Press Stylebook employs the term ″ZIP code.″ The Chicago Manual of Style makes use of the term ″zip code.″

‘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.To listen to the interview with Deirdre Mask (which begins about the 7:15 mark), please use the player at the top of the page, or you can read the text of the interview below.
