Area Code 3667 – Pokrovan

Overview of Area Code 3667

Area code 3667 is a geographic National Destination Code (NDC) within the Bulgarian telephone numbering plan, assigned to the town of Pokrovan and its immediate surrounding area. Pokrovan is a small settlement located in the northwestern part of Bulgaria, administratively part of the Vidin Province. The code is used for fixed-line (PSTN) services, and numbers under this code are allocated to residential and business subscribers within the local exchange area.

Geographic Coverage and Administration

The 3667 code covers the administrative territory of Pokrovan, including the town itself and nearby villages that fall under the same local telephony exchange. The area is served by the Bulgarian Telecommunications Company (BTC, operating as Vivacom), which historically held a monopoly on fixed-line services. Since the liberalization of the Bulgarian telecom market, alternative operators may also provide fixed-line services using this code, but the geographic assignment remains unchanged.

Dialing Formats

When calling a fixed-line number in Pokrovan, the dialing format depends on the caller's location:

• Local calls (within Bulgaria, same area code): Dial only the subscriber number, which is typically 4 to 5 digits long. For example, if the subscriber number is 12345, dial 12345.
• National calls (from other areas in Bulgaria): Dial the trunk prefix 0, followed by the area code 3667, and then the subscriber number. For example, to reach the same subscriber, dial 0 3667 12345.
• International calls (from outside Bulgaria): Dial the international access prefix (e.g., 00 from most countries, or +), then the country code 359, the area code without the leading zero (3667), and the subscriber number. For example, from the US, dial 011 359 3667 12345; from most European countries, dial 00 359 3667 12345. When using a mobile phone, simply dial +359 3667 12345.

Overlay and Numbering Plan Considerations

Bulgaria's numbering plan does not currently have overlay codes for geographic areas; each geographic area has a unique NDC. The number length for geographic numbers in Bulgaria is typically 8 digits after the country code, including the NDC. For area code 3667, the subscriber number length is 4 or 5 digits, making the total national significant number (NSN) length 8 digits (e.g., 3667 1234 or 3667 12345).

Caller Instructions

For callers within Bulgaria, always include the trunk prefix 0 when dialing from a different area. For international callers, remember to drop the leading 0 and use the country code +359. Be aware that calls to geographic numbers are typically charged at standard national or international rates, depending on the caller's location and tariff plan. Fixed-line numbers in Bulgaria are not portable to mobile networks, but they can be ported between fixed-line operators within the same geographic area.
