ISO 3166-2:NO

ISO 3166-2:NO 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:

• 19 counties
• 2 territories (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 NO, the ISO 3166-1 alpha-2 code of Norway. The second part is two digits:

• 01–20 (except 13): counties
• 21 and 22: Svalbard and Jan Mayen

The digits are the official number of the county used in Norway, which is assigned following the coastline from the Swedish border in the southeast to the Russian border in the northeast (13 was used by Bergen, which was merged into Hordaland in 1972).

Collectively Svalbard and Jan Mayen is also assigned its own set of country codes in ISO 3166-1, with alpha-2 code SJ.
