What Is the Purpose of Zip Codes?

ZIP codes in the United States are a form of postal code. Individuals who send letters or parcels through the United States Postal Service (USPS) must include the code in their address. This five-digit identifier expedites the delivery of packages to their intended destination. In fact, zip, which stands for Zone Improvement Plan, denotes swiftness and velocity.

By examining the numbers in these codes, a mail sorter can determine where a package should be delivered. Each digit in a ZIP code represents a distinct location or region within the United States (US). Some represent large regions, such as the east or west coast, while others represent particular states, cities, and villages.

Each code’s initial digit corresponds to a broad regional area. This is typically a group of adjacent states. For instance, codes commencing with zero represent the states of New England, including Maine, Massachusetts, Vermont, and Connecticut. Additionally, they represent US territories such as Puerto Rico and the US Virgin Islands.

On the other hand, states on the west coast are typically represented by nine-digit zip codes. For example, California, Oregon, and Washington all have codes beginning with nine. Alaska and Hawaii also have nine-digit postal codes.

The following two numerals identify a particular sectional center facility. These USPS facilities are responsible for further categorizing mail. Frequently, they are located in major urban centers.

The final two digits indicate an even more specific location, typically a post office. This resides within the region indicated by the first numeral. Additionally, it is frequently near to the sectional center facility.

Some addresses that manage a high volume of incoming mail may have unique postal codes. The White House, for instance, has the postal code 20006. Other government buildings in the United States have also been assigned codes beginning with 202 to 205, independent of their location. Universities and other institutions of a comparable nature may also have their own postal codes.

Sometimes, although it is not required, a package is addressed with nine-digit codes. Sometimes, this form of code is referred to as a ZIP+4 code. The first five digits of these codes are followed by a hyphen and then the remaining four digits. Typically, these final four digits designate a particular block or street.
