Area Code 3676 – Benkovski, Kardzh.

Geographic Context and Coverage

The area code 3676 is a geographic National Destination Code (NDC) within the Bulgarian numbering plan, assigned under the country calling code +359. It serves the region of Benkovski, located in the Kardzhali Province (Kardzh. is the standard abbreviation). This area is part of the Eastern Rhodopes, and the code covers the town of Benkovski along with the surrounding villages and rural localities that fall within its local exchange area. Administratively, the region falls under the jurisdiction of the Municipalities of Kardzhali and Kirkovo, depending on the exact settlement. The code is used for fixed-line PSTN services, and subscribers within this area share a common local calling area.

Dialing Formats and Procedures

When calling a number in the Benkovski area, the dialing format depends on the caller's location:

• Local calls (within the 3676 area): Subscribers can dial the subscriber number directly, typically consisting of 5 to 6 digits, without the trunk prefix or area code. For example, if the local number is 12345, a local caller would simply dial 12345.
• National calls (from other parts of Bulgaria): Callers must use the trunk prefix 0 followed by the area code and the subscriber number. For instance, to call a number in Benkovski from Sofia, you would dial 0 3676 12345.
• International calls (from outside Bulgaria): Callers should dial the international access prefix (00 or +), then the country code 359, followed by the area code without the leading 0, and the subscriber number. For example, from the United States, you would dial 011 359 3676 12345 or +359 3676 12345 on a mobile phone.

Numbering Plan and Overlays

Bulgaria's numbering plan follows ITU-T E.164 recommendations. The area code 3676 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 in this area; the code is exclusive to the Benkovski exchange. However, number portability is available in Bulgaria, allowing subscribers to retain their numbers when changing operators, but the geographic significance remains for fixed-line numbers.

Practical Guidance for Callers

For local businesses and residents, it is essential to display numbers in international format when communicating with foreign clients: +359 3676 [subscriber number]. When dialing from abroad, always omit the initial '0' of the trunk prefix. For travelers within Bulgaria, using the national format with the leading '0' is required for calls from other regions. The code is not used for mobile services; mobile numbers in Bulgaria start with 87, 88, 89, 98, 99, etc., and are non-geographic.
