📍 Geographic Location of Belitsa, Hask.
Geographic Overview
The +359 3755 prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network serving the town of Belitsa and its surrounding area in the Haskovo Province of southern Bulgaria. This region, situated in the Upper Thracian Plain, is known for its agricultural production and proximity to the Greek border. The code is administered under the national numbering plan of Bulgaria, which follows ITU-T E.164 recommendations.
Dialing Formats
When calling a Belitsa fixed-line number from within Bulgaria, subscribers must dial the trunk prefix 0 followed by the area code and the local subscriber number. For example, to reach a local number such as 123456, you would dial:
- National format: 0 3755 123456
- International format: +359 3755 123456 (when calling from abroad)
The local subscriber number typically consists of 6 digits, making the complete national significant number (NSN) 9 digits (excluding the leading trunk prefix). The international format omits the leading zero and uses the +359 country code.
Caller Instructions
For callers within Bulgaria, always use the trunk prefix 0 before the area code. For callers from other countries, replace the trunk prefix with the +359 country code. Ensure you have the correct international exit code for your country (e.g., 00 from most European countries, 011 from the United States).
Overlay and Numbering Considerations
Currently, the 3755 area code is not subject to an overlay; it serves exclusively the Belitsa geographic area. However, as with all fixed-line services in Bulgaria, number portability allows subscribers to retain their numbers when switching between fixed-line operators, provided they remain within the same geographic area. This means that the prefix does not necessarily indicate the physical network operator, but it does indicate the geographic location of the subscriber's line.
Regulatory Notes
The Bulgarian Communications Regulation Commission (CRC) oversees the allocation and management of numbering resources. The 3755 code is part of the closed numbering plan of Bulgaria, where the maximum number length is 12 digits including the country code. Calls to this prefix are typically charged at standard local or national rates, depending on the caller's location and tariff plan.
