Caller Instructions
For local callers within Topolovgrad: If you are calling from a landline within the same area code, you may need to dial the full national number (including the area code) depending on the current dialing plan. In Bulgaria, the national dialing plan requires the use of the trunk prefix '0' and the area code for all calls, even local ones, unless you are using a direct extension system. Therefore, always dial 0470 followed by the subscriber number.
For callers from other Bulgarian regions: Dial 0, then 470, then the subscriber number. For example, from Sofia, you would dial 0470 123456.
For international callers: Dial your country's international access code (e.g., 00 from most European countries, or 011 from the US/Canada), then Bulgaria's country code 359, then the area code 470 (without the leading 0), and finally the subscriber number. For instance, from the US, you would dial 011 359 470 123456.
