ISO is the entry for Norway 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 Norway, ISO 3166-2 codes are defined for the following subdivisions:
- 11 counties
- two arctic regions (i.e., Svalbard and Jan Mayen, territories in the Arctic region separated from metropolitan Norway)
Each code consists of two parts separated by a hyphen. The first part is , the ISO 3166-1 alpha-2 code of Norway. The second part is two digits.
Collectively Svalbard and Jan Mayen is also assigned its own country code in ISO 3166-1, with alpha-2 code .
Currently the standard matches the county codes assigned by the Norwegian government from 2020 to 2024. The government split the counties of Troms and Finnmark, Viken and Vestfold and Telemark effective by January 2024, which are not reflected in ISO 3166-2.
