Area Code 51 – Andrijevica/Berane/Blue/Gusinje/Petnitsa/Rožaje

Geographic Coverage and Administrative Jurisdiction

The +382 51 numbering block is a geographic National Destination Code (NDC) allocated to the northern and eastern municipalities of Montenegro. It serves the towns of Andrijevica, Berane, Gusinje, Petnjica, and Rožaje, as well as the surrounding villages and rural settlements. These municipalities fall under the jurisdiction of the northeastern statistical region of Montenegro, bordering Serbia and Kosovo. The area is characterized by mountainous terrain, including the Prokletije range, and is known for its forestry, agriculture, and emerging eco-tourism.

Dialing Formats and Caller Instructions

When calling a fixed-line subscriber within the +382 51 area from abroad, the international format is used: +382 51 X XX XX (where X denotes the subscriber's local number digits). From within Montenegro, callers must dial the trunk prefix 0 followed by the NDC and the subscriber number: 051 X XX XX. For example, a landline in Berane might be reached internationally as +382 51 234 567, and domestically as 051 234 567.

Local calls within the same NDC area can be made using the seven-digit subscriber number without the area code, depending on the operator's network configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format when calling from mobile phones or VoIP services.

Numbering Plan and Overlay Considerations

Montenegro's numbering plan follows ITU-T E.164, with geographic NDCs ranging from 2 to 9 digits in length. The +382 51 block is a geographic code, meaning that the tariff and routing are based on the physical location of the line. As of the latest updates, there are no overlay codes for this area; the 51 NDC is unique to the listed municipalities. However, number portability is available, allowing subscribers to retain their numbers when changing operators, even if they move outside the geographic area, which can occasionally lead to non-geographic usage of a geographic code.

Services and Usage

Subscribers in the +382 51 area are primarily served by fixed-line PSTN and VoIP networks. The code is used for residential, business, and public services, including local government offices, schools, and healthcare facilities. Internet access is typically provided via ADSL, VDSL, or fiber-optic connections, with VoIP services increasingly common. For international callers, it is essential to check time zones (Central European Time, UTC+1, with daylight saving) and to be aware that calls to Montenegrin landlines are typically charged at higher rates than calls to mobile numbers, depending on the caller's operator.
