Area Code 3773 – Kapitan Andreevo

Geographic Overview

The +359 3773 area code is a geographic National Destination Code (NDC) assigned to the Kapitan Andreevo region in Bulgaria. Kapitan Andreevo is a border settlement located in Haskovo Province, southeastern Bulgaria, at the border with Turkey. It is primarily known for the Kapitan Andreevo border checkpoint, one of the busiest land border crossings in the Balkans. The code serves the town and its immediate administrative surroundings, including nearby villages within the Svilengrad municipality.

Dialing Formats

When calling a landline in Kapitan Andreevo from within Bulgaria, subscribers must dial the national trunk prefix 0 followed by the area code and the local subscriber number. The local numbers typically consist of 6 to 7 digits, resulting in a complete national format of 0 3773 XXX XXX (or 0 3773 XXX XX depending on the local number length). For example, a local number might be dialed as 03773 12345 from a Bulgarian mobile or fixed line.

For international callers, the country code for Bulgaria is +359, and the leading trunk prefix 0 is omitted. Therefore, the international dialing format becomes +359 3773 XXX XXX. For instance, to reach a subscriber with the local number 12345, an international caller would dial +359 3773 12345.

Caller Instructions

Local callers (within Bulgaria): Dial the full national number, including the trunk prefix: 0 3773 XXX XXX. This applies to calls from fixed lines and mobile phones. If you are physically within the Kapitan Andreevo area, you still must dial the trunk prefix and area code for all calls, as Bulgaria does not use local dialing without the area code.

International callers: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), followed by Bulgaria's country code 359, then the area code 3773 (without the leading zero) and the subscriber number. For example, from the US you would dial 011 359 3773 12345.

Regulatory and Technical Notes

As a geographic code, +359 3773 is allocated by the Communications Regulation Commission (CRC) of Bulgaria. The code is used exclusively for fixed-line PSTN and VoIP services that are registered to the Kapitan Andreevo area. Number portability is available in Bulgaria, so a number with this prefix may be routed to a different operator, but the geographic association remains. Overlay codes are not in effect for this area; the 3773 code is the sole NDC for Kapitan Andreevo.

When dialing from abroad, ensure you have the correct international exit code, as it varies by country. Also, be aware that some VoIP providers may require you to use the international format even for domestic calls if you are using a service based outside Bulgaria.
