Svalbard and Jan Mayen

Svalbard and Jan Mayen is a statistical designation defined by ISO 3166-1 of two parts of Norway under separate jurisdictions—Svalbard and Jan Mayen. While the two are combined for the purposes of the International Organization for Standardization category, they are not administratively related. This has further resulted in the country code top-level domain .sj being issued for Svalbard and Jan Mayen, and ISO 3166-2:SJ. The United Nations Statistics Division also uses this code, but has named it Svalbard and Jan Mayen Islands. Wikipedia
