The principal settlement is the town of Krum, located approximately 20 kilometers northeast of the provincial capital, Haskovo.

Dialing Formats and Instructions
For callers within Bulgaria, dialing a fixed-line number in Krum requires the trunk prefix 0, followed by the area code 3925 and the subscriber number, which typically consists of 5 to 6 digits. The complete national format is: 0 3925 XXX XXX (or fewer digits depending on the local number length). For example, a local number might be dialed as 03925 12345 from any Bulgarian phone.
For international callers, the Bulgarian country code +359 replaces the trunk prefix. The international format is: +359 3925 XXX XXX.

Overlay and Numbering Considerations
As of the latest ITU-T operational bulletin, no overlay code has been assigned for the Krum area. The 3925 code is the sole geographic NDC for this locality. However, due to the migration towards VoIP and mobile services, the number of fixed-line subscriptions in rural areas has been declining. Nevertheless, the geographic code remains active and is used for traditional PSTN services as well as for fixed-line VoIP services that retain geographic numbering.
Caller Instructions
- Local callers (within Krum): If you are calling from another fixed-line number within the same area code, you may need to dial only the subscriber number, depending on your local exchange. However, for clarity and consistency, it is recommended to always use the full national format: 03925 XXXXX.
- National callers (from other Bulgarian cities): Dial 0 + 3925 + subscriber number. Example: 0 3925 12345.
- International callers: Dial your country's international access code (e.g., 00 from most European countries, 011 from North America), then 359 (Bulgaria's country code), then 3925 and the subscriber number. Example: 00 359 3925 12345 or 011 359 3925 12345.
When storing Bulgarian numbers in international format, always use the plus sign: +359392512345. This format is universally recognized and ensures proper routing from any network, including mobile and VoIP services.
