Overview of Area Code +47 79
Area code 79 is the geographic National Destination Code (NDC) assigned to the Svalbard and Jan Mayen archipelagoes within the Norwegian numbering plan. These remote Arctic territories are part of the Kingdom of Norway but are not part of the Schengen Area or the EEA, which influences their telecommunication administration. The code is used for fixed-line services (PSTN) and some VoIP-based local numbers.
Geographic Coverage and Jurisdiction
The code covers all inhabited settlements in Svalbard, primarily Longyearbyen (the administrative center), Barentsburg, and Ny-Ålesund, as well as the tiny meteorological outpost on Jan Mayen. Calls to these islands are routed via the Norwegian national network, but due to their unique status, special international dialing procedures apply from outside Norway.
Dialing Formats
- Local dialing (within Svalbard/Jan Mayen): Subscriber numbers are typically 5 digits long, and local calls are made by dialing the 5-digit number directly, without the area code.
- National dialing (from mainland Norway): Dial 79 followed by the 5-digit subscriber number, e.g., 79 12345. Note that the leading trunk prefix '0' is not used in Norway; the national significant number is 8 digits (NDC + subscriber).
- International dialing (from outside Norway): Dial the international access prefix (e.g., 00 or +), then 47 (Norway country code), then 79 and the subscriber number. Example: +47 79 12345.
Caller Instructions
For callers within Norway: Simply dial 79 followed by the local number. No trunk prefix is required. For international callers: Use the +47 country code and omit any leading zeros. For instance, to call a number in Longyearbyen, you would dial +47 79 XXXXX. It is important to note that calls to Svalbard from abroad are often billed as international calls, even though the destination is part of Norway. Conversely, calls from Svalbard to mainland Norway are considered national calls and are dialed using the standard Norwegian numbering plan.
Overlay and Numbering Considerations
There is no overlay code for Svalbard; the 79 code is exclusive to these territories. Subscriber numbers are allocated by the Norwegian Communications Authority (Nkom) and are used by local fixed-line operators and some VoIP providers. Mobile services in Svalbard are provided via satellite or through local GSM networks that use separate mobile codes, so 79 is primarily associated with fixed-line and VoIP services.
