U.S. State Postal Abbreviations

These postal abbreviations are distinguished from traditional abbreviations such as Calif., Fla., or Tex.

The United States Postal Service has established a set of abbreviations to help process mail with optical character recognition and other automated equipment.[6] There are also official USPS abbreviations for other parts of the address, such as street designators (street, avenue, road, etc.).

The traditional abbreviations for U.S. states and territories, widely used in mailing addresses prior to the introduction of two-letter U.S. postal abbreviations, are still used for other purposes, and are still recognized by the U.S. Postal Service.

The table below shows the US Postal Service (USPS) abbreviation for each of the United States, districts, territories, and possessions.
