Caller Instructions
For local callers: If you are within the Gorski izvor area, you may be able to dial the subscriber number directly without the area code, depending on your local exchange configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format (0 3936 ...).
For international callers: Replace the international access code (e.g., '00' from most European countries, '011' from North America) with the Bulgarian country code +359, then dial the area code 3936 followed by the subscriber number. Do not include the trunk prefix '0'.
Overlay and Numbering Plan Considerations
As of the latest ITU-T national numbering plan updates, the Haskovo region does not have an overlay code; the 3936 prefix is exclusively assigned to the Gorski izvor exchange. This means that local calls within the same geographic area do not require an additional area code. However, due to the liberalization of the Bulgarian telecom market, subscribers may have their numbers ported to alternative fixed-line operators, but the geographic significance of the prefix remains unchanged.
