Its lifespan as county is only temporary, as it was decided to cease to exist from January 1st 2024. It is the largest county by area in Norway, encompassing about 75,000 square kilometres (29,000 sq mi).

The political and administrative offices are based in city of Tromsø (the seat of the old Troms county). The county governor is based in town of Vadsø (the seat of the old Finnmark county). The two towns are about 800 kilometres (500 mi) apart, approximately a 10-hour drive by car. On 1 January 2024, the county will be demerged back to the counties Finnmark and Troms; parliament decided that on 15 June 2022; the Tjeldsund Municipality from Nordland county will belong to Troms county.
