📍 Geographic Location of Oslo
Geographic Coverage and Administrative Jurisdiction
The Norwegian prefix +47 2360 is a geographic number allocated within the Oslo numbering area. Oslo, the capital of Norway, serves as the administrative and economic hub of the country. This prefix is part of the National Destination Code (NDC) framework under the ITU-T E.164 standard, specifically designated for fixed-line services in the Oslo region. Numbers bearing this prefix are typically assigned to businesses and residents within the city limits and its immediate surroundings, including major districts such as Sentrum, Grünerløkka, and Frogner.
Dialing Formats and Procedures
For local callers within Norway, the number is dialed as an 8-digit national significant number: 23 60 xx xx. No trunk prefix '0' is used, as Norway employs a closed numbering plan without a leading zero. For international callers, the full international format must be used: +47 23 60 xx xx (or 0047 23 60 xx xx from countries using the international prefix 00). The plus sign (+) represents the international access code, which varies by country (e.g., 011 from the United States).
Overlay and Numbering Plan Considerations
Oslo does not currently have an overlay code; the city is served by the single geographic area code 2, with prefixes like 2360 providing additional numbering capacity. This means that local calls within Oslo do not require an area code, but calls from other Norwegian regions must include the full national number. Since the implementation of number portability in Norway, subscribers may retain their 2360 number even if they move to a different operator, but the geographic tie remains to the original exchange area.
Caller Instructions
- Local callers (within Oslo): Dial the 8-digit number directly (e.g., 23 60 12 34).
- National callers (outside Oslo): Dial the same 8-digit number; no area code is needed.
- International callers: Dial your country's exit code, then 47, then the 8-digit number (e.g., from the UK: 00 47 23 60 12 34; from the US: 011 47 23 60 12 34).
This prefix is used for traditional PSTN and VoIP fixed-line services. When calling from abroad, ensure you omit any leading zero that might be part of the local format—though in Norway, no leading zero exists. Always verify the complete number with the recipient, as misdialing can lead to unintended destinations within the Oslo numbering range.
