Look Up a ZIP Code™

ZIP Code™ is a postal code system used in the United States. It was introduced by the United States Postal Service (USPS) in 1963 to improve mail delivery efficiency. The term "ZIP" stands for "Zone Improvement Plan."

Each ZIP Code™ is a five-digit number that represents a specific geographic area for sorting and delivering mail. The first digit of the ZIP Code™ represents a group of states, with the higher numbers assigned to states further west. The following two digits narrow down the location to a specific region or city, and the final two digits identify a more specific area within that region.

Over time, the ZIP Code™ system has expanded to include additional codes to accommodate population growth and the need for more precise mail sorting. This includes the addition of ZIP+4® codes, which further narrow down the delivery area to a specific block or group of addresses.

ZIP Codes™ are widely used not only for mail sorting but also for various purposes, such as demographic analysis, marketing, and delivery logistics. They are commonly used in online forms, address databases, and mapping applications.

It is important to note that ZIP Codes™ are specific to the United States and are not used in other countries. Other countries have their own postal code systems, such as Canada's Postal Code and the United Kingdom's Postcode.

To look up a specific ZIP Code™, simply enter the city, state, county or zip code location you are searching for, and the system will provide you with the corresponding ZIP Code™.
