Area Code 3776 – Raykova mogila

Geographic Coverage and Administrative Jurisdiction

The +359 3776 prefix is a geographic National Destination Code (NDC) assigned to the town of Raykova mogila and its immediate surrounding areas within the Sliven Province of central Bulgaria. This code is part of the Bulgarian PSTN (Public Switched Telephone Network) numbering plan, administered by the Communications Regulation Commission (CRC) under the ITU-T E.164 international standard. Subscribers under this prefix are served by fixed-line infrastructure, typically via copper or fiber-optic connections, and are geographically tied to the local telephone exchange.

Primary Cities and Local Dialing

Raykova mogila is a small settlement, and the 3776 code covers the village itself along with nearby hamlets in the Sliven municipality. For local callers within the same NDC, the full national number is dialed as 03776 XXX XX (where X represents the subscriber number). The leading zero is a trunk prefix used only for domestic calls within Bulgaria. For callers from other Bulgarian regions, the same format applies: dial 0 followed by the NDC and subscriber number.

International Dialing Format

For international callers, the leading zero is omitted. The complete international number format is +359 3776 XXX XX or +3593776XXXXX when written without spaces. This format is essential for routing calls through international gateways. For example, to call a landline in Raykova mogila from the United States, you would dial 011 359 3776 XXX XX; from the UK, it would be 00 359 3776 XXX XX.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 3776 area, meaning the geographic region is exclusively served by this NDC. However, number portability allows subscribers to retain their 3776 numbers when switching to alternative fixed-line operators, including cable or VoIP providers, as long as they remain within the same geographic area. This can occasionally lead to a non-geographic routing of calls, but the number's geographic significance remains for administrative and emergency services.

Caller Instructions

• Local callers (within Bulgaria): Always dial the trunk prefix 0 before the area code. Example: 03776 123 45.
• International callers: Use the country code +359, drop the leading zero, and dial the full number. Example: +359 3776 123 45.
• Emergency services: In Bulgaria, dial 112 for general emergencies; this is independent of the geographic code.

Understanding the correct dialing format is crucial for both residential and business communications. For businesses in Raykova mogila, using the +359 3776 prefix in international marketing materials ensures accurate call routing and reinforces local presence.
