Iso 3166-2:do

ISO 3166-2:DO 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 Dominican Republic, ISO 3166-2 codes are defined for 10 regions, 31 provinces and 1 district. The Distrito Nacional contains the capital of the country Santo Domingo and has special status equal to the provinces.

Each code consists of two parts, separated by a hyphen. The first part is DO, the ISO 3166-1 alpha-2 code of the Dominican Republic. The second part is two digits:

  • 01: district
  • 02–27: provinces as of late 1970s
  • 28–30: provinces created in the 1980s and 1990s
  • 31–32: provinces created in 2001 and 2002
  • 33–42: regions
