📍 Geographic Location of Konyovo
Overview of Area Code 4520 (Konyovo, Bulgaria)
Area code 4520 is a geographic National Destination Code (NDC) within the Bulgarian national numbering plan, allocated to the region of Konyovo (also transliterated as Konyovo or Konjovo). Konyovo is a village located in southeastern Bulgaria, within the administrative jurisdiction of Sliven Province. The code serves the town and its immediate rural surroundings, providing fixed-line PSTN services to residential and business subscribers.
Geographically, Konyovo lies in the Thracian Plain, approximately 20 kilometers south of the city of Sliven. The area is primarily agricultural, with small local enterprises and public institutions relying on the fixed network. The prefix 4520 is part of the larger Sliven numbering area, which uses the trunk prefix 0 followed by the NDC. In international format, the full number is written as +359 4520 XXX XXX, where the total subscriber number length is typically 6 digits after the country code (including the NDC).
Dialing Formats
For callers within Bulgaria, the national dialing format requires the trunk prefix 0 before the area code. To reach a Konyovo number, local callers must dial:
- 0 4520 XXX XXX (national format)
For international callers, the Bulgarian country code +359 replaces the trunk prefix, and the area code is used without the leading zero:
- +359 4520 XXX XXX (international format)
For example, a local number in Konyovo might be 04520 12345 when dialed domestically, and +359 4520 12345 from abroad. Note that the subscriber number length may vary, but the total length after the country code is typically 9 digits for geographic numbers in Bulgaria.
Overlay and Numbering Considerations
Currently, there is no overlay plan for area code 4520, meaning that the geographic area is served exclusively by this NDC. However, as with all Bulgarian geographic codes, number portability is available for fixed-line services, allowing subscribers to retain their numbers when changing operators within the same geographic area. Callers should be aware that the cost of a call to Konyovo depends on the caller's operator and tariff plan; calls from mobile phones may be charged at higher rates than fixed-to-fixed calls.
For businesses or individuals seeking to establish a presence in Konyovo, obtaining a local number with area code 4520 can enhance local credibility and reduce long-distance charges for customers in the region. When dialing from abroad, always use the international prefix of your country (e.g., 00 from most European countries) followed by 359 and the area code without the leading zero.
