Area Code 3756 – Valche pole

Geographic Overview and Administrative Jurisdiction

The +359 3756 prefix is a geographic National Destination Code (NDC) assigned to the town of Valche pole (Вълче поле) and its immediate surrounding area within the Dobrich Province (Област Добрич) of northeastern Bulgaria. This numbering area falls under the administrative jurisdiction of the General Terms and Conditions for the provision of electronic communications networks and/or services, as regulated by the Communications Regulation Commission (CRC) of Bulgaria. The code is part of the national numbering plan aligned with ITU-T E.164, ensuring international dialing compatibility.

Primary Cities and Coverage Area

The Valche pole exchange primarily serves the municipal center of Valche pole and nearby villages within the municipality of Valche pole (Община Вълче поле). This is a predominantly rural area known for agriculture and viticulture, located near the Bulgarian Black Sea coast but inland from the port city of Varna. The geographic coverage is limited to a specific wireline exchange area; therefore, the prefix is not used for mobile or nomadic services.

Dialing Formats and Caller Instructions

For local callers within Bulgaria, the dialing format is 0 3756 XXX XX (where X denotes the subscriber number). The leading '0' is the trunk prefix used for domestic calls. For international callers, the format is +359 3756 XXX XX or 00 359 3756 XXX XX (depending on the international access code of the originating country). When dialing from a mobile phone, the plus sign (+) is recommended to ensure proper routing regardless of the caller's location.

Example: To call a landline in Valche pole with subscriber number 12345, a caller from the United States would dial 011 359 3756 12345, while a caller from the United Kingdom would dial 00 359 3756 12345. A caller from Sofia (Bulgaria) would dial 0 3756 12345.

Overlay and Numbering Considerations

As of the current CRC numbering plan, there is no overlay code for the Valche pole area. The 3756 code is unique to this exchange, and no area code changes have been announced. Subscriber numbers within this prefix are typically 5 to 7 digits long, but the total length of the national significant number (NSN) after the trunk prefix is 8 digits (including the NDC). For international dialing, the country code (+359) is followed by the NDC (3756) and the subscriber number, resulting in a total E.164 number length of 12 digits (including the country code).

Callers should note that while Bulgaria has implemented number portability for both fixed and mobile services, fixed-line numbers are generally tied to the geographic exchange. If a subscriber has ported their number to another operator, the call will still be routed to the Valche pole exchange area, but the service provider may differ.
