ISO 3166-2:NO

ISO is the entry for Norway in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization, which defines codes for the names of the principal subdivisions 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

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 "Troms and Finnmark", "Viken" and "Vestfold and Telemark" effective by January 2024, which as of 2026 are not reflected in ISO 3166-2.
