**[ISO](/source/International_Organization_for_Standardization) 3166-2:US** is the entry for the [United States](/source/United_States) in [ISO 3166-2](/source/ISO_3166-2), part of the [ISO 3166](/source/ISO_3166) standard published by the [International Organization for Standardization](/source/International_Organization_for_Standardization) (ISO), which defines [codes](/source/Code) for the names of the principal [subdivisions](/source/Administrative_division) (e.g., [provinces](/source/Province) or [states](/source/State_(administrative_division))) of all [countries](/source/Country) coded in [ISO 3166-1](/source/ISO_3166-1).

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

- [50 states](/source/List_of_states_and_territories_of_the_United_States)
- one district (i.e., the [District of Columbia](/source/District_of_Columbia), the capital of the country, also known as Washington, D.C.)
- six [insular areas](/source/Insular_area) (including the [U.S. Minor Outlying Islands](/source/U.S._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](/source/ISO_3166-1_alpha-2) code of the United States. The second part is two letters, which is the [postal abbreviation](/source/List_of_U.S._state_abbreviations) of the state, district, or outlying area, except the United States Minor Outlying Islands which do not have a postal abbreviation.
