    1. 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.
    2. On the map above, you can see ZIP codes that are close to me.
    3. ZIP codes are still referred to as ″US postal codes″ by certain people.
    4. ZIP is an acronym that stands for Zone Improvement Plan.
    5. 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.
    1. The additional four digits allow the United States Postal Service to more accurately categorize mail for delivery.
    2. 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

    1. The first number of a ZIP code in the United States often denotes a group of states in the United States.
    2. 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.
    3. 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.
    4. 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.
    5. The sec centers are not available to the general population and perform the majority of their sorting at night.
    1. 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.
    2. The number 0 is closer to white on the map, while the number 9 is considerably more vibrant.
    3. 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).
    4. Although the ZIP+4 code is not essential, it does assist the post office in sorting mail in an extra manner.
    5. A ZIP+4 code may equate to a city block, a group of residences, or a single high-volume receiver, depending on the situation.
    6. 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

    1. As you can see from the map, ZIP codes are not issued to every location in the United States.
    2. There are not enough deliverable addresses in remote and particularly rural sections of the nation to support the creation of a mail route.
    3. A ZIP code is not required if there is no postal delivery.
    4. 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

    1. Despite the fact that ZIP codes appear to be of a geographical character, this was not their original use.
    2. They are meant to consolidate mail in order to help the United States Postal Service to carry mail more effectively.
    3. It is common for ZIP codes to span numerous states in order to improve the efficiency of mail routing and delivery.
    4. 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.
    5. Some ZIP codes, on the other hand, have nothing to do with geographical places.
    1. For example, the United States Navy uses a single ZIP code for all of its mail.
    2. 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.
    3. 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

    1. According to the most recent USPS data, there is no official ZIP code map.
    2. The primary problem has already been discussed: there isn’t always a clearly defined geographic limit for a ZIP code.
    3. 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.
    4. 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.
    5. They offer an extremely accurate representation of the geographic region covered by a ZIP code.
    1. When you look at our maps, you will quickly see that there are some border concerns.
    2. 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.
    3. 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)

    1. The United States Census Bureau created the tabulation regions for ZIP code numbers in the 1950s.
    2. Their objective is to provide statistical information on geographical areas that are recognizable to the majority of residents.
    3. ZCTAs, on the other hand, are not precisely the same as ZIP codes.
    4. Because of the difficulties in exactly defining the geographic region encompassed by a ZIP code, as previously stated.
    5. 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.
    1. ZCTAs are also not updated on a regular basis like ZIP codes are.
    2. In general, they are updated once every ten years in order to coincide with the United States Census.
    3. 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).
    4. Consider the image on the right, which depicts a city block that corresponds to a normal census block.
    5. All four sides are bordered by sections of city streets, each with its own name and address, which surround the entire area.
    6. 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

    1. Keep in mind that ZIP codes were created to make mail delivery more convenient.
    2. Their limits were not drawn in accordance with existing boundaries, such as those of cities, counties, or even states.
    3. 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.
    4. ZIP codes often do not cross state boundaries, although there are several that do (65733, 71749, and 73949 are good examples).
    5. 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.
    1. 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.
    2. The margins of the boundaries frequently overlap with one another.
    3. 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.
    4. The assignment for cities is a little more difficult to figure out.
    5. The United States Postal Service (USPS) does not always utilize the city in which the ZIP code is situated.
    6. 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.

    Where Was the First Zip Code Issued?

    1. Contrary to popular belief, Adjuntas in Puerto Rico received the honor of having the world’s first ZIP Code – or, more specifically, the world’s first five-digit ZIP Code – ever used by the United States Postal Service.
    2. Due to the fact that the ZIP Code system was completely adopted and implemented in 1963, and since the zone maps prepared by the United States depicted Puerto Rico as the ″first″ section of the United States, with the map traveling from right to left throughout the nation, this was the case.
    3. The first ZIP Code in the United States was 00601, and it designated a significant portion of Puerto Rico as the first Zone Improvement Plan (ZIP) in the country.
    4. As previously said, the ZIP Codes continued to increase in number as they moved from the East Coast to the West Coast, with ZIP Codes such as 01001 being assigned to Agawam, Massachusetts, and 90210 being assigned to Beverly Hills, California, to name a few examples.
    5. Interestingly enough, the lowest ZIP Code number now in use by the United States Postal Service is 00501, which is assigned to the Internal Revenue Service in Holtsville, New York.
    1. The ZIP Code with the highest number in the United States Postal Service system is 9950, and that ZIP Code was assigned to Ketchikan, Alaska – which is the westernmost place according to the Zone Improvement Plan mapping scheme, at any rate – in the United States.

    How Are Zip Codes Assigned?

    1. Undoubtedly, one of the most crucial things to understand is that ZIP Codes are not issued or allocated by any precise border that can be found on a typical United States map.
    2. There is a common misconception among those who believe that ZIP Codes are issued by state, or that differing state and town borders aid in the division and designation of various ZIP Code numbers that are associated with distinct locales.
    3. That is not at all how the situation is now unfolding.
    4. Instead, ZIP Codes have been divided down and allocated in accordance with the Zone Improvement Plan, which was formed by the United States Postal Service in order to better distinguish distinct delivery routes inside their own internal systems, rather than the previous approach.
    5. This is something that many people are astonished to hear, since they did not realize that the entire ZIP Code system was designed to increase overall mailing efficiency and delivery time.
    1. But when you start comparing different ZIP Codes on a map, it becomes a lot easier to understand – for example, comparing the ZIP Codes for Christian County, Kentucky and Montgomery County, Tennessee (which are both 42223) or the ZIP Codes for Lake County, Oregon and Modoc County, California (both 97635) – it becomes a lot clearer.
    2. Only regional centers of the United States postal system, how different postal routes are assembled, and how the United States Postal Service (USPS) has opted to better break up and construct distinct delivery routes across the board are included in the drawing of the boundaries.
    3. This is how you wind up with the United States Navy having ZIP Codes that begin with 095, for example, all throughout the country (and in foreign countries) and all having the same ZIP Code.
    4. Once you realize that state boundaries are not a decisive factor in how these ZIP Codes were assigned (in fact, they are just incidental to the process), the entire ZIP Code map becomes much easier to comprehend moving forward.

    What’s the Zip Code +4 System?

    1. While the original ZIP Code platform did wonders for making mail delivery a whole lot easier and a whole lot more efficient in the 1960s, the United States Postal Service (USPS) decided in 1983 (20 years after adopting the five digit ZIP Code) to enhance the system even more.
    2. The United States Postal Service (USPS) decided in 1983 to add a fourth digit to the end of its ZIP Code designations, giving these ZIP Codes a complete nine character code and allowing for even faster delivery times.
    3. With these additional four digits, it is now possible to define separate delivery segments along various streets, different city blocks, and even in various apartment groups – which is very useful if one or more neighborhoods receives a large volume of mail that must be delivered.
    4. Another thing to note is that none of this has anything to do with geographical boundaries or anything else of the kind.
    5. The odds are fairly likely that if you have two apartment buildings directly close to one another in downtown Boston, and both of them get massive amounts of mail on a daily basis, each of them will have its own +4 ZIP Code designation.
    1. Although they are physically adjacent to one another and may have consecutive street addresses, the chances of them having consecutive +4 ZIP Code designations (even though they are physically adjacent to one another and may have consecutive street addresses) are slim to none if the apartment building on the left was built in the 1990s and the apartment building on the right was built in the 2000s.

    Are There Any Special Zip Codes Out There?

    1. In addition to the renowned 90210 code for Beverly Hills, which was named after the same television show that we discussed previously, there are a number of other unusual ZIP Codes to consider.
    2. Additionally, we said before that the IRS has exclusive use of the lowest ZIP Code designation in the country, but you might be interesting to hear that just two persons in the country have their own ZIP Code as well.
    3. Neither the President of the United States nor the First Lady of the United States of America have their own unique ZIP Code designations that they – and only them – may use to their advantage.
    4. In addition to the President’s ZIP Code (20500–0001), the First Lady’s ZIP Code (20500–0002) is also available.
    5. Those ZIP Codes are ″branches″ of the ZIP Code for the White House (20500), and there are a number of additional +4 ZIP Code designations for other branches, offices, and pieces of the White House that have been added on top of that.
    1. Smoky Bear, the mascot of the United States Forest Service, is the only other ″person″ who has been assigned their own ZIP Code.
    2. In response to his growing popularity and a large advertising campaign launched in order to fight back against forest fires, Smoky began receiving a massive volume of mail in the form of fan letters.
    3. Smoky’s daily mail volume increased to such an extent that he was assigned the ZIP Code 20252, which he has retained to this day (despite the fact that it was briefly deactivated/decommissioned in the early 1990s).
    4. An additional highly intriguing ZIP Code to look into is that of Conyngham, Pennsylvania, which is located in the state of Pennsylvania.
    5. There are 2000 people who reside in this town, which uses the ZIP Code 18219, yet they are bordered on all sides by the Pennsylvania town of Sugarloaf, which uses the ZIP Code 18249, which has the ZIP Code 18249.
    6. In fact, it is the only spot in the United States where one ZIP Code is completely encapsulated within another ZIP Code!

    Other Interesting Facts You (Probably) Never Knew About Zip Codes

    1. According to the USPS Zone Improvement Plan, as we discussed previously, the ZIP Code is made up of numbers that correlate to a range of various designations inside the ZIP Code.
    2. First and foremost, the code represents the National Area regional code, with the second digits indicating the Sectional Center or the largest regional post office as a subset of the first digit.
    3. After the first five digits, the remaining two digits of the ZIP Code are directly associated with either associated post offices or the actual delivery region.
    4. The first two digits of these additions to the ZIP Code are especially for streets that serve large buildings, which is why they are included in the +4 ZIP Code expansion.
    5. The second and third codes refer to the side of the street on which the building is located and the exact floor on which the address is located, respectively.

    2. If an area has a major town or city, the United States Postal Service (USPS) would frequently award it the first ZIP Codes.
    3. Following that, the ZIP Codes will be shown in alphabetical order.
    4. 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.
    5. This facility serves as the mail sorting and distribution hub for a certain zone or geographic area or region.
    1. Some divisional center facilities have numerous three-digit codes given to them, which makes it difficult to locate them.
    2. 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.
    3. The fourth and fifth digits of the ZIP Code show the geographical location of the city or municipality.
    4. 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.
    1. ZIP Codes do not represent physical areas; instead, they identify address groupings or delivery routes.
    2. Although most ZIP Codes may be loosely allocated to a geographic location, ZIP Codes do not represent geographic regions.
    3. As a result, ZIP Code ″areas″ might overlap with one another, be included within another ZIP Code, or have no geographical boundaries at all.
    4. 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.
    5. 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).
    1. Because they are based on few delivery routes, the boundary between ZIP Code zones is indeterminate in certain places.
    2. See our guidelines on how to locate a county by ZIP Code for further information.
    3. 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

    1. The United States Postal Service (USPS) modified its ZIP Code system in 1983 to incorporate the new ZIP+4.
    2. 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.
    3. 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.
    4. Using a ZIP+4 Code is not essential, as it is often computed automatically during the sorting and processing of the mail.
    5. ZIP+4 Codes are formatted as follows: As a general rule, each Post Office Box is assigned a unique ZIP+4 code.
    1. 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.
    2. Because of this variation, the ZIP+4 Code for each Post Office Box must be searched up individually.
    3. Not all USPS deliverable addresses have a ZIP+4 code allocated to them, despite the fact that the majority of them do.
    4. For some addresses, geocoding lookups or address validation that need a ZIP+4 may not be successful, depending on the address type.
    5. 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.
    6. 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

    1. On Wednesday, the United States will celebrate the 52nd anniversary of the adoption of ZIP codes.
    2. 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.
    3. 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.
    4. The first zoning address system was implemented in 1943, and it has been in use ever since.
    5. 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.
    1. The numbers were designed to make sorting easier for personnel who were less familiar with the system.
    2. 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.
    1. 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).
    2. 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

    1. Several ZIP codes were updated in 1983, with the addition of a hyphen and a four-digit number.
    2. Because mail could no longer be separated into categories using simply standard ZIP codes, the ZIP+4 code was introduced.
    3. However, it never gained widespread acceptance.
    4. The development of sorting technology shortly after it was used rendered it mostly ineffective and obsolete.
    5. 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.
    1. 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.
    2. 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.
    3. With the use of ZIP codes, it is possible to acquire a plethora of information about the people who live in a certain location.
    4. This information includes things like age, education level, gender, and race.

    Schenectady, NY – 12345

    GE District is an abbreviation for General Electric District.On top of that, it’s strange that the Electric City only has zip codes that begin with the number 123 to begin with.It also has a zip code that looks like this, which makes it simple for children to assume that this is Santa Claus’s address.It just makes sense, doesn’t it?If you want to know what happens to all of Kris Kringle’s mail, you may find out by visiting this page.

    Fishers Island, NY – 06390

    Because it is closer to Connecticut than New York, it has a Connecticut zip code.To be fair, there are times when you are technically in New York, as a part of Long Island Suffolk County, but you must go through Connecticut in order to get to the Island.That’s a strange occurrence.However, what makes it truly bizarre is the fact that Connecticut has Zip Codes that begin with 06, whereas this is located in New York.Strange, isn’t it?

    Their mail is delivered through Connecticut.

    Holtsville, NY – 00501

    The Zip Code with the Lowest Population in the United States So, my first concern with regard to this is, why the number 00501?Please, America, reply to my message.Why didn’t you start the zip code system with a well-known number like 00000 or at the very least 00500?In any case, another New York city has made it into the top five.It’s really good.

    This is the zip code for Smokey Bear.In all seriousness, why does Smokey Bear have a postal code?Is it true that this cartoon character receives a large amount of mail?This appears to be completely ridiculous to me.Perhaps I’m being too harsh in my evaluation.

    Robert Moon, an Inventor of the ZIP Code, Dies at 83 (Published 2001)

    Look at the story in its original context, which was published on April 14, 2001 in Section C, Page 6.Home delivery and digital subscribers are entitled to a special perk known as Buy ReprintsTimesMachine.A hospital in Leesburg, Florida, said on Tuesday that Robert A.Moon, a career postal employee who in 1963 won a 20-year battle for what would become known as the ZIP code, had passed away.Moon was 76.

    He is unquestionably the originator of the first three digits of the alpha-numeric code.Mr.Moon was 83 years old and was a resident of a nursing facility in Leesburg.

    • The Zoning Improvement Plan, or ZIP as it was more commonly known, represented an irreversible step in the apparent ascendancy of numbers over letters.
    • It was implemented at the same time that the telephone company switched from letter exchanges such as BUtterfield 8 to seven-digit numbers, a move that was criticized at the time.
    • Big Brother and ″numerical neurosis,″ according to newspaper editorials, were on the horizon.
    • However, at a time when outdated delivery methods were failing, ZIP codes helped to speed up the delivery of mail.

    Planes transported far more mail than railways, which allowed for more leisurely sorting on mail cars, and the volume of business mail was increasing at an alarming rate.Furthermore, because the mail was being routed through increasingly automated regional hubs rather than from city to city, old-fashioned hand sorting by city, state, and neighborhood was no longer possible.The Postal Service, which was then administered by the Cabinet-level Post Office Department, required a national code in order to classify mail as quickly as possible.Perhaps of even greater long-term significance was the ease with which mass marketers would be able to use ZIP codes to pinpoint demographic groups, such as areas with high incomes or areas with a high number of people applying for credit cards.

    This was something that had not been anticipated at the time.Nobody, and I mean no one, could have conceived ″Beverly Hills 90210.″ Mr.Moon’s wife, Barbara Moon, claimed her husband initially presented his concept for coding addresses by numbers in 1944, while he was working as a postal inspector, but that it was never implemented.She has a notion as to why this is happening.

    • The Moons received a gold lavaliere engraved with the initials ″Mrs.
    • ZIP″ from their husband as a wedding gift.
    • ″We were registered Republicans, and it happened to be Democrats in at the time,″ Mrs.

    Moon explained.It was not until at least the third time that Mr.Moon submitted his concept to the top that it was adopted, and even then, it was not in a straightforward
