Geographic codes in Bulgaria are regulated by the Communications Regulation Commission (CRC) and follow the ITU-T E.164 international numbering standard. The prefix 3178 is used for fixed-line (PSTN) services, connecting subscribers within the Krasnovo exchange area to the national and international telephone networks.

Dialing Formats and Instructions

For callers within Bulgaria, the national trunk prefix is 0, followed by the area code and the subscriber number. The local subscriber number length in the 3178 area is typically 5 or 6 digits, resulting in a total national significant number (NSN) of 8 to 9 digits (excluding the trunk prefix). The complete national dialing format is:

• National (from within Bulgaria): 0 3178 XXX XXX
• International (from abroad): +359 3178 XXX XXX

For example, a local number in Krasnovo might be dialed as 0 3178 45 678 from within Bulgaria, or as +359 3178 45 678 from any other country. When calling from a mobile phone in Bulgaria, it is common to use the international format with +359, as it works seamlessly across all networks.

Callers from outside Bulgaria must replace the trunk prefix '0' with the country code +359. No additional access codes are required for international calls, but you should check with your service provider for any international dialing prefixes (e.g., 00 in most European countries).

Geographic Coverage and Overlays

The 3178 area code serves the village of Krasnovo and possibly a few nearby hamlets. Krasnovo is located approximately 15 kilometers northeast of Haskovo city. The region is predominantly rural, with agriculture and small local businesses as primary economic activities.

For businesses or residents in Krasnovo, having a geographic number reinforces local presence and can reduce call costs for local customers. However, with the rise of VoIP and mobile services, many users opt for non-geographic numbers for flexibility. Still, geographic codes like 3178 remain essential for traditional fixed-line connectivity and are often preferred for official registrations and emergency services.
