ISO 3166-2:US

ISO 3166-2:US is the entry for the codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.

Currently for the United States, ISO 3166-2 codes are defined for the following subdivisions:

Each code consists of two parts, separated by a hyphen. The first part is US, the ISO 3166-1 alpha-2 code of the United States. The second part is two letters, which is the postal abbreviation of the state, district, or outlying area, except the United States Minor Outlying Islands which do not have a postal abbreviation.
