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.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.

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.
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.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.By experimenting with the Smarty US ZIP Code API or reading our ZIP Code API documentation, you can discover further possibilities.

About US ZIP Codes
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
- A single high-volume address that is unique (for example, 20505 for the CIA in Washington, DC)
- Only a PO Box (for example, 22313 for the PO Boxes in Alexandria, Virginia)
- Armed forces
- 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).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.
- 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.
