📍 Geographic Location of Østfold/Akershus
Geographic Coverage and Administrative Jurisdiction
The Norwegian country code +47 is followed by the area code 68, which designates a geographic numbering area covering the counties of Østfold and Akershus in southeastern Norway. This region includes key municipalities such as Fredrikstad, Sarpsborg, Moss, Halden, and parts of the greater Oslo metropolitan area. The 68 prefix is allocated under the Norwegian Communications Authority (Nkom) and is used for fixed-line PSTN and VoIP services that are geographically tied to this region.
Dialing Formats and Number Structure
Norwegian national significant numbers (NSN) are eight digits long, including the area code. For numbers within the 68 area, the local format is 68 XX XX XX when dialed from another Norwegian fixed or mobile line. Internationally, callers must use the full international format: +47 68 XX XX XX. The leading '0' is not used in Norwegian dialing; the country code +47 is directly followed by the area code and subscriber number.
Caller Instructions
Local callers (within the 68 area) can dial the eight-digit number directly without any trunk prefix. Domestic callers from other Norwegian regions also dial the eight-digit number, as Norway does not use a trunk prefix like '0'. International callers must dial the international access prefix (e.g., 00 from most countries, or + from mobile) followed by 47 and the eight-digit number.
Overlay and Numbering Considerations
Norway does not use area code overlays in the traditional sense; each geographic area has a unique two-digit code. However, due to the close proximity to Oslo, some numbers in the 68 area may be used by businesses that operate across multiple counties. Number portability allows subscribers to retain their 68 numbers when moving within Norway, but the geographic association remains for routing purposes.
Usage and Services
The 68 prefix is primarily used for fixed-line services, including residential and business lines. It is also used for VoIP services that register a physical address in the region. Calls to 68 numbers are typically charged at standard national rates, depending on the caller's operator. Emergency services (110/112/113) are always free and do not require an area code.
