Area Code 3136 – Rozino, Plovdiv

Geographic Overview and Administrative Jurisdiction

The +359 3136 prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network serving the village of Rozino and its immediate vicinity. Rozino is administratively part of Plovdiv Province, located in the central-southern region of Bulgaria. The area falls under the regulatory oversight of the Communications Regulation Commission (CRC) of Bulgaria, which allocates numbering resources in accordance with the national numbering plan and ITU-T E.164 recommendations.

Coverage Area and Local Significance

This code specifically covers the village of Rozino, which is situated in the municipality of Karlovo, within Plovdiv Province. The geographic area is characterized by a mix of residential, agricultural, and small commercial activity. Subscribers within this code are typically connected to the local PSTN exchange, and the code is not shared with adjacent villages, ensuring that calls are routed accurately to the intended destination.

Dialing Formats and Caller Instructions

• International format: +359 3136 XXX XXX (where X represents the local subscriber number). For example, a full international number might appear as +359 3136 12345.
• National format (within Bulgaria): 0 3136 XXX XXX. The leading '0' is the trunk prefix used for domestic calls. Thus, a caller from Sofia would dial 0 3136 12345.
• Local format (within the same code): In many cases, local calls within the same exchange can be made using only the subscriber number (XXX XXX), but this depends on the specific carrier's dialing plan. It is always safe to use the full national format.

For callers from abroad, the international access prefix (e.g., 00 from most European countries, or 011 from North America) is followed by the Bulgarian country code 359, then the area code without the leading '0', and finally the subscriber number. Example: 00 359 3136 12345.

Overlay and Numbering Considerations

As of the latest CRC updates, there are no overlay codes for the 3136 area. The numbering plan is closed, meaning that the number length is fixed. All geographic numbers in Bulgaria are 8 digits after the country code, including the NDC. Therefore, the subscriber number within the 3136 code is 5 digits long, resulting in a total of 8 digits (3136 + 5 digits). This structure ensures efficient routing and avoids ambiguity.

Callers should note that while mobile numbers in Bulgaria are also 8 digits after +359, they begin with '8' (e.g., +359 8XX XXX XXX). Geographic codes like 3136 are exclusively for fixed-line services. If you receive a call from +359 3136, it originates from a landline in the Rozino area, not a mobile phone.

For businesses or individuals in Rozino, having a local geographic number enhances trust and local presence. International callers should be aware that calls to this number are billed according to standard international rates to Bulgaria, which may vary by provider.
