Area Code 3111 – Parvenets, Plovdiv

Overview of +359 3111

The +359 3111 numbering block is a geographic area code assigned to the town of Parvenets and its surrounding areas within the Plovdiv Province of Bulgaria. It is part of the national numbering plan administered by the Communications Regulation Commission (CRC) under ITU-T E.164 guidelines. As a geographic prefix, it routes calls to fixed-line (PSTN) subscribers whose physical lines are connected to local exchanges in this region.

Coverage and Administration

Parvenets is a small town located approximately 15 kilometers south of Plovdiv, the second-largest city in Bulgaria. The code 3111 serves the town itself and nearby villages within the administrative jurisdiction of the Plovdiv municipality. The area is characterized by residential neighborhoods and light industrial activity, with fixed-line services provided by local operators such as A1 Bulgaria, Vivacom, and Yettel, as well as alternative carriers using local loop unbundling.

Dialing Formats

• National dialing (within Bulgaria): Dial 0 3111 XXX XXX (where X represents the subscriber number). The leading '0' is the trunk prefix used for domestic calls.
• International dialing (from abroad): Dial +359 3111 XXX XXX (or 00359 3111 XXX XXX from most countries). The country code +359 replaces the trunk prefix '0'.

Subscriber numbers in this area are typically 6 digits long after the area code, resulting in a total national significant number (NSN) of 9 digits (including the leading '0' for domestic calls). For example, a local number might be 0 3111 234567 when called from Sofia, or +359 3111 234567 when called from the United States or the United Kingdom.

Caller Instructions

• Local callers (within Parvenets): In many cases, local calls can be made using only the 6-digit subscriber number without the area code, depending on the operator's dialing plan. However, it is safer to dial the full national format (0 3111 XXX XXX) to ensure proper routing.
• Domestic callers from other Bulgarian regions: Always dial 0 3111 followed by the subscriber number.
• International callers: Replace the trunk prefix '0' with the country code +359, so the full international format is +359 3111 XXX XXX.

Overlay and Numbering Considerations

As of the latest CRC updates, there is no overlay code for the 3111 area. The Plovdiv region uses multiple area codes (e.g., 32 for Plovdiv city, 3111 for Parvenets), and number portability is available for fixed-line services, allowing subscribers to retain their numbers when changing operators within the same geographic area. However, porting does not change the geographic association of the prefix.

Usage and Practical Information

This prefix is used exclusively for fixed-line services, including traditional PSTN and VoIP-based fixed lines that are registered to a physical address in the area. It is not used for mobile services, which are assigned non-geographic prefixes starting with 87, 88, 89, and 98. Businesses and residents in Parvenets rely on this code for local communications, and international callers should be aware that call charges are typically higher than calls to major city codes due to the smaller population density.
