Area Code 122 – Bagakhangai

Overview of Area Code 122 (Bagakhangai, Mongolia)

Area code 122 is a geographic National Destination Code (NDC) assigned to the Bagakhangai district, an administrative enclave located within the borders of the Mongolian capital, Ulaanbaatar. Bagakhangai operates as a separate municipal entity under the national administrative framework, and its telecommunications services are routed through this dedicated area code. The district is primarily residential and industrial, with a modest population, and its numbering plan follows the ITU-T E.164 standard for Mongolia.

Geographic Coverage and Administrative Jurisdiction

Bagakhangai is situated approximately 40 kilometers southeast of central Ulaanbaatar. Despite its proximity to the capital, it maintains its own local government and, consequently, its own telecommunication exchange. The area code 122 covers all fixed-line telephone services within the district's boundaries, including government offices, local businesses, and private residences. There are no overlay codes in effect; 122 remains the sole geographic code for this area.

Dialing Formats and Caller Instructions

• Local calls within Bagakhangai: When calling a number within the same area code, subscribers typically dial only the 6-digit subscriber number (e.g., 123456). However, some networks may require the full national number.
• National calls from other regions in Mongolia: Callers must dial the trunk prefix 0, followed by the area code 122, and then the subscriber number. For example, to reach a Bagakhangai landline from Ulaanbaatar, dial 0 122 123456.
• International calls from abroad: Callers should dial the Mongolia country code +976, then the area code 122 (without the leading trunk zero), and the subscriber number. For instance, a call from the United States would be dialed as 011 976 122 123456 (or +976 122 123456 on mobile phones).

Numbering Plan and Technical Notes

Mongolian fixed-line numbers are typically 8 digits in length when including the area code. In the case of Bagakhangai, the full national number comprises the area code 122 followed by a 6-digit subscriber number, totaling 8 digits (excluding the trunk prefix 0). This structure aligns with the national numbering plan administered by the Communications Regulatory Commission of Mongolia. The area code is exclusively assigned to fixed-line PSTN services; mobile and VoIP services are non-geographic and use different prefixes.

For callers outside Mongolia, it is essential to omit the trunk prefix '0' when dialing the international format. Additionally, when storing numbers in international databases, the format should be +976 122 XXXX XX to ensure proper routing. Bagakhangai's geographic isolation means that international calls are routed via the national backbone, and no special international access arrangements apply.
