ISO 3166-2:BR

ISO 3166-2:BR is the entry for Brazil 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.

Main article: ISO 3166-2

Currently for Brazil, ISO 3166-2 codes are defined for 26 states and 1 federal district. The Federal District has a special status similar to the states.

Each code consists of two parts, separated by a hyphen. The first part is BR, the ISO 3166-1 alpha-2 code of Brazil. The second part is two letters, widely used in Brazil as abbreviations of the states and federal district.

  prefix 1		   RO AC AM RR PA AP TO
  11 12 13 14 15 16 17
Nordeste
  prefix 2		   MA PI CE RN PB PE AL SE BA 
  21 22 23 24 25 26 27 28 29
Sudeste
  prefix 3		   MG ES RJ SP
  31 32 33 35
Sul
  prefix 4		   PR SC RS

It is not part of ISO standandard, but there are a direct mapping between ISO codes and IBGE numbers. IBGE is the authority of the ISO codes, and defined both, codes and numbers.
