📍 Geographic Location of Hordaland
Geographic Coverage and Administration
The +47 55 prefix is a geographic National Destination Code (NDC) assigned to the Hordaland region in western Norway, with its primary concentration in the city of Bergen. Administratively, the code falls under the jurisdiction of the Norwegian Communications Authority (Nkom), which oversees the national numbering plan in accordance with ITU-T E.164 recommendations. The service area encompasses Bergen, Norway's second-largest city, and its surrounding municipalities, including Askøy, Øygarden, and Bjørnafjorden. The code is used for fixed-line PSTN and VoIP services, and it is not portable to mobile networks, as mobile numbers in Norway use distinct prefixes (e.g., 4, 9).
Dialing Formats and Caller Instructions
For local callers within Norway, the number is dialed as an 8-digit national significant number (NSN), beginning with the trunk prefix '0' followed by the NDC and the subscriber number. For example, a typical Bergen fixed-line number would be dialed as 055 12 34 56 from within Norway. However, when calling from abroad, the trunk prefix is omitted, and the full international format is used: +47 55 12 34 56. This format applies to both landline and mobile callers. It is important to note that the NDC '55' is not separated by a space in the international format; the subscriber number follows directly after the country code and area code.
Overlay and Numbering Considerations
As of the latest Nkom updates, there is no overlay code for the Hordaland region; the 55 prefix remains the sole geographic code for the Bergen area. This means that no additional area codes have been introduced for this region, simplifying dialing procedures. However, due to the growth of VoIP and the migration of fixed-line services to IP-based networks, some numbers assigned with the 55 prefix may not be tied to a physical address, but they remain geographically associated with the Hordaland region for routing and emergency services purposes. For foreign callers, it is essential to remember that Norway's country code is +47, and there is no trunk prefix when dialing from abroad. Always replace the leading '0' of the national dialing format with the international access code of your country (e.g., 00 from most European countries) followed by 47.
