📍 Geographic Location of Akershus
Geographic Overview
The Norwegian country code +47 is followed by the geographic area code 64, which designates the Akershus region. Akershus surrounds the capital, Oslo, and includes key municipalities such as Lillestrøm, Skedsmo, Nittedal, and Rælingen. The code 64 is allocated to fixed-line services within this area, covering both residential and business subscribers.
Dialing Formats
For local calls within Norway, subscribers dial the eight-digit national number, which includes the area code 64 followed by a five- to six-digit subscriber number. For example, a local call to a subscriber in Lillestrøm might be dialed as 64 85 00 00. When calling from abroad, the international format is used: +47 64 85 00 00 (or 0047 64 85 00 00 from most countries). The leading zero is not used in the international format.
Regulatory and Technical Context
Under the ITU-T E.164 numbering plan, the country code +47 is assigned to Norway, and geographic area codes like 64 are part of the National Destination Code (NDC). The Norwegian Communications Authority (Nkom) oversees number allocation. Fixed-line numbers in the 64 range are typically associated with traditional PSTN and VoIP services. In recent years, number portability allows subscribers to retain their numbers when switching providers, even if the service is moved to a different technology.
Caller Instructions
- Local callers within Norway: Dial the eight-digit number starting with 64 (e.g., 64 85 00 00). No trunk prefix is needed.
- International callers: Dial the international access code (e.g., 00 from most countries), followed by Norway's country code 47, then the area code 64 and the subscriber number, omitting any leading zero. Example: 00 47 64 85 00 00.
- From mobile phones in Norway: The same national format applies; the area code is required even when calling from a mobile.
Overlay and Future Considerations
As of the latest Nkom updates, there are no overlay codes for the 64 area. However, with the ongoing transition to all-IP networks, geographic numbers are increasingly used for nomadic VoIP services, meaning the physical location may not strictly correspond to the area code. Despite this, the 64 code remains a reliable indicator of the Akershus region for callers and businesses.
