ISO 3166-2:US

From Wikipedia, the free encyclopedia

ISO 3166-2:US is the entry for the United States in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines 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:

  • 50 states
  • 1 district (i.e., the District of Columbia, the capital of the country, also known as Washington DC)
  • 6 insular areas (including the United States Minor Outlying Islands, a collection of nine islands or groups of islands). (The subdivision category name used to refer to the grouping of insular areas is "outlying area" per the standard, but these locales are not "outlying" from a local perspective.)

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.

Current codes[edit]

Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
