Belashtitsa lies approximately 15 kilometers south of Plovdiv, the country's second-largest city, and is part of the greater Plovdiv metropolitan area.

Geographic Coverage and Administrative Jurisdiction
The 3100 area code serves the administrative territory of Belashtitsa municipality, including the town itself and surrounding rural settlements. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) infrastructure of the region, historically operated by the incumbent operator (formerly BTC, now A1 Bulgaria). While fixed-line services dominate, some VoIP providers may also assign numbers with this code, but the geographic association remains for routing and emergency services.
Dialing Formats and Instructions
For local callers within Bulgaria, dialing a Belashtitsa number requires the trunk prefix 0 followed by the area code and subscriber number. The full national format is: 0 3100 XXX XXX (where X represents the 6-digit subscriber number). For example, a local call would be dialed as 03100 123456.
For international callers, the format is: +359 3100 XXX XXX. For instance, to call a Belashtitsa number from abroad, you would dial +359 3100 123456. Note that the leading '0' is omitted when using the international prefix.
Overlays and Numbering Changes
Currently, there is no overlay code for the 3100 area. However, as Bulgaria's telecommunications market evolves, number portability allows subscribers to retain their numbers when switching operators, even if they move outside the original geographic area. This means a number with the 3100 code may not always be physically located in Belashtitsa, but the code still identifies the original geographic allocation.
Caller Instructions
When calling from a foreign country, always use the international access prefix of your country (e.g., 00, 011) followed by Bulgaria's country code 359, then the area code without the leading zero, and the subscriber number. For calls within Bulgaria, use the trunk prefix 0. For example, a caller in the United States would dial 011 359 3100 123456, while a caller in Sofia would dial 03100 123456.
