It covers the 50 states, 1 federal district, 5 territories, and a collection of 9 minor outlying islands. The first part of the code is the 2-character ISO 3166-1 country code US and the second part of the code is the 2-character region code which is the same as the U.S. postal abbreviation (except UM.)
