ISO 3166-2:NG is the entry for Nigeria 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 Nigeria, ISO 3166-2 codes are defined for 1 capital territory and 36 states. The Federal Capital Territory contains the capital of the country Abuja and has special status equal to the states.
Each code consists of two parts, separated by a hyphen. The first part is NG, the ISO 3166-1 alpha-2 code of Nigeria. The second part is two letters.
Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
