Administrative Areas

Primary Administrative Areas

  • Every location will have one primary administrative area assigned to it.
  • The primary administrative area is designated by the Level: 1 code in the AdministrativeArea block of the response.
  • Admin Codes have been derived from the ISO 3166-2 codes, where available, focusing on the principal subdivisions. 
  • If the principal subdivisions of a particular country are not available, the code "00" will be assigned to all locations in that country.  The name of the country will be assigned as the administrative name for any "00" codes.
  • In the event that a principal subdivision has not yet had an ISO 3166-2 code assigned to it, a code ranging from "X01" to "X99" will be assigned as a place holder until the official code has been released.
  • Each primary administrative area will also include the administrative classification, such as State, Province, etc.
