American Samoa is administratively divided into three districts (Western, Eastern and Manu‘a) and two unorganized atolls (Swains Island and Rose Atoll). The districts are subdivided into 15 counties, which are composed of 76 villages. For statistical purposes, the United States Census Bureau counts the three districts and two unorganized atolls as five county equivalents, while treating the actual counties as minor civil divisions. American Samoa has only one U.S. zip code: 96799.
