Geographic Coverage and Administrative Jurisdiction

Dialing Formats and Caller Instructions

For callers within Bulgaria, the national dialing format requires the trunk prefix 0 followed by the area code and subscriber number.

Overlay Considerations and Numbering Plan

As of the latest updates, there are no overlay codes for 3077; the area code is unique to this geographic region. However, number portability is available in Bulgaria, allowing subscribers to retain their numbers when switching providers, but the geographic significance of the code remains tied to the original location. For local callers, dialing the full national number is always required, as local 7-digit dialing is not used in Bulgaria.

Practical Usage and Examples
