Area Code 2512 – Baruun-Urt city, Sukhbaatar

Overview of Area Code 2512

Area code 2512 is a geographic destination code within the Mongolian national numbering plan, assigned to the city of Baruun-Urt, the administrative center of Sukhbaatar Province (aimag) in eastern Mongolia. As a geographic code, it routes calls to fixed-line (PSTN) subscribers within this specific locality, following the ITU-T E.164 international standard.

Geographic Coverage and Administrative Jurisdiction

Baruun-Urt is the capital and largest city of Sukhbaatar aimag, located approximately 560 kilometers southeast of Ulaanbaatar. The area code 2512 serves the urban and suburban fixed-line network of Baruun-Urt, including government offices, businesses, and residential customers. It does not cover mobile numbers, which are assigned non-geographic prefixes (e.g., 8xxx series).

Dialing Formats and Instructions

• National dialing (within Mongolia): To call a fixed-line number in Baruun-Urt from another part of Mongolia, dial 0 2512 XXXXX. The leading 0 is the national trunk prefix, followed by the area code 2512 and the subscriber number (typically 5 to 6 digits). For example, a local number might be dialed as 0 2512 34567.
• International dialing (from abroad): Callers outside Mongolia should dial the international access prefix (e.g., 00 or +), followed by Mongolia’s country code 976, then the area code without the leading zero, and the subscriber number. For instance, +976 2512 34567.
• Local calls within Baruun-Urt: When dialing within the same area code, the national trunk prefix and area code may be omitted, depending on the local network configuration. However, for clarity and consistency, it is recommended to use the full national format.

Overlay and Numbering Plan Considerations

Mongolia’s numbering plan does not currently implement overlays for geographic area codes. Each geographic region has a unique code, and number portability is not widely available for fixed lines. Therefore, the area code 2512 remains strictly associated with Baruun-Urt and its immediate surroundings. The subscriber number length may vary; always verify the exact length with the local provider.

Caller Guidance

For local callers within Mongolia, ensure you include the trunk prefix 0 when dialing from a mobile or from a different fixed-line area. For international callers, remember to replace the trunk prefix with the +976 country code. If you are unsure about the subscriber number length, contact the Mongolian Communications and Information Technology Authority or your service provider for assistance.
