Area Code 12 – Pozarevac

Overview of Area Code +381 12

Area code 12 is a geographic National Destination Code (NDC) within the Republic of Serbia's national numbering plan, as defined under ITU-T E.164. It serves the city of Požarevac and its surrounding municipalities in the Braničevo District. The code is assigned to fixed-line (PSTN) services, and calls to numbers beginning with +381 12 are routed to the public switched telephone network in this specific region.

Geographic Coverage and Administrative Jurisdiction

The +381 12 area code covers Požarevac, an administrative center of the Braničevo District in eastern Serbia. The region includes the town of Požarevac itself, as well as nearby settlements such as Kostolac, Petrovac na Mlavi, and Žabari, depending on the specific local exchange boundaries. The code is used for both residential and business fixed-line subscribers within this area.

Dialing Formats

• National dialing (within Serbia): When calling a fixed-line number in Požarevac from another part of Serbia, subscribers must dial the trunk prefix 0 followed by the area code 12 and the subscriber number. For example, a local number might be dialed as 012 345 678.
• International dialing (from abroad): Callers outside Serbia should dial the international access prefix (e.g., 00 or +), followed by Serbia's country code 381, then the area code 12 (without the leading zero) and the subscriber number. For instance, to reach a number in Požarevac, you would dial +381 12 345 678.

Local Call Routing and Overlays

Within the Požarevac area, calls between fixed-line numbers sharing the same local exchange may be dialed as local calls, but the exact dialing procedure depends on the operator and the specific exchange. As of the current numbering plan, there are no overlay codes for this region, meaning that the 12 area code is unique to Požarevac and does not share its geographic area with another NDC. However, subscribers should always verify the correct dialing format with their service provider, especially when calling from mobile networks.

Caller Instructions

• Local callers (within Požarevac): If you are calling from a fixed-line phone within the same exchange, you may be able to dial only the subscriber number. However, for calls from other parts of Serbia, always use the full national format: 0-12-XXX-XXX.
• Foreign callers: Always replace the leading zero with the country code +381. For example, a number written locally as 012 345 678 should be dialed as +381 12 345 678 from abroad.

Numbering Plan Considerations

Serbia's numbering plan follows the ITU-T E.164 recommendation. The maximum length of a national significant number (NSN) is 12 digits, including the leading trunk prefix '0'. For area code 12, subscriber numbers typically consist of 6 to 7 digits, resulting in a total NSN of 9 to 10 digits (including the leading 0). The country code +381 is assigned to Serbia by the International Telecommunication Union.
