What Are Zip Codes?
A ZIP Code is a postal code used by the United States Postal Service to find places in the country (USPS). Introduced in 1963, the basic format had five digits in it. In 1983, an extended ZIP+4 code was made available. It had the five digits of the ZIP Code, followed by a hyphen and four more digits that helped people find more specific places.
“ZIP” is an acronym for Zone Improvement Plan, and it was chosen to imply that mail moves more swiftly and efficiently when the ZIP code is included in a postal address by mailers. The US Postal Service (USPS) initially registered the term “ZIP Code” as a service mark; however, that registration was subsequently revoked in 1997.

What Are The Types Of Zip Codes?
The ZIP Codes come in four different types:
- Unique: assigned to a single address with a lot of people.
- Post Office Box-only: used only for PO Boxes at a certain place, not for any other deliveries.
- In the military, they use them to get mail for the US government.
- There are a lot of other ZIP Codes that are standard.
1. Unique zip codes
Unified postal codes (ZIP codes) are high-volume mail receivers that accept mail at a single place and subsequently distribute the mail within the organization. Big corporations, government buildings, universities, and large medical facilities are among the types of organizations that employ unique ZIP codes.
2. Military zip codes
In addition to being assigned their own ZIP Code, which corresponds closely to the Military Gateway city’s ZIP, each APO and FPO is also organized by country or region — the first two numbers designate the routing center, the third number designates the country or region within the “state,” and the fourth number designates the routing center within the “country”
3. Post office Box
ZIP codes are critical to your success if you want to ensure that your postal mail is processed efficiently and without any delays or bottlenecks. The ZIP codes allow postal agencies such as the United States Postal Service (USPS) to quickly identify and sort postal mail sent to a specific destination. Postal mail may be delayed if ZIP codes are not included in it. Postal mail that does not have a ZIP number on it may be required to be handled manually, resulting in unnecessary delays that could have been avoided if you had provided the ZIP codes in advance.
4. Standard zip codes
In certain extreme circumstances, a ZIP Code theoretically of the Standard type may be used in practice as one of the other three types. When it comes to Columbus, Ohio’s ZIP Code 43210, it is classified as a Standard-type ZIP Code. Because its geographic borders are essentially coterminous with those of the Ohio State University’s main campus, it is effectively unique to the university, even if it is not formally a “Unique” ZIP Code of the type used by other businesses and organizations.
The most expensive zip codes can be under any of these categories.
Why Are Zip Codes Used?
Here are a few reasons why zip codes are used in the U.S.
1. ZIP codes are a sort of postal code that is used in the United States
Individuals who send letters or packages through the United States Postal Service (USPS) are required to include the code as part of the address on the correspondence. This five-digit code is used to guarantee that parcels arrive at their designated location as quickly as possible. Even the name zip, which stands for Zone Improvement Plan, evokes a sense of urgency and rapidity.

2. It makes it easy to sort and deliver
A postal sorter can decide where a parcel should be delivered by looking at the numbers contained in these codes.
ZIP codes are used to designate specific areas or regions of the United States, and each digit represents one of these areas or regions (US). Some are used to represent vast geographic areas, such as the east or west coasts, while others are used to represent specific states, cities, and towns. When you look at any of the codes, the first digit refers to a vast geographic region.
Typically, this refers to a group of states next to one another. For example, the New England states, including Maine, Massachusetts, Vermont, and Connecticut, are represented by codes that begin with the number zero. They also represent US territory, such as Puerto Rico and the US Virgin Islands, internationally.
When it comes to zip codes, those that begin with the number nine generally correspond to states around the west coast. For example, the states of California, Oregon, and Washington all have zip codes that begin with the number nine.
Additionally, Alaska and Hawaii have zip codes that begin with the number nine. The following two digits designate a specific sectional center facility, and so on. These United States Postal Service facilities are in charge of sifting the mail even further. They are frequently found in densely populated metropolitan regions.
3. The final two digits represent a particular location
The final two digits designate an even more particular location, which is typically a post office. This is situated within the geographical area denoted by the first digit of the code. It is also usually in close proximity to the sectional center facility as well. It is possible for some addresses that handle a considerable volume of incoming mail to have their own zip numbers, which are referred to as unique zip codes.
The White House, for example, features the zip code 20006 on its door. Apart from the White House, other government buildings in the United States have been issued codes that begin with the numbers 202 through 205, regardless of where they are located. University campuses and other similar facilities may also have their own postal codes assigned to them.
