ISO 3166-2:DO

Main article: ISO 3166-2

ISO 3166-2:DO is the entry for the Dominican Republic 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 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

Current codes
