Area Code 2372 – Darkhan city, Darkhan-Uul

Overview of Mongolia's +976 2372 Geographic Code

The +976 2372 prefix is a geographic National Destination Code (NDC) assigned to the Darkhan city area within Darkhan-Uul Province, Mongolia. It is used for fixed-line PSTN (Public Switched Telephone Network) services, connecting subscribers in Mongolia's second-largest industrial and educational hub. Darkhan is strategically located about 230 km north of Ulaanbaatar, near the Trans-Mongolian Railway, and serves as a major center for construction and manufacturing.

Coverage and Administrative Jurisdiction

This code covers the urban and suburban zones of Darkhan city, including the administrative districts (khoroo) under the Darkhan-Uul provincial government. It does not cover other provinces or mobile numbers, which use non-geographic prefixes. The region is subdivided into two main zones: Darkhan (the city proper) and the nearby industrial area of Khongor, though the 2372 prefix is specifically allocated to the city's fixed-line network.

Dialing Formats and Instructions

• Local calls (within Darkhan): Dial the 7-digit subscriber number directly, e.g., 1234567. The trunk prefix '0' and area code are not required.
• Domestic long-distance calls (from other Mongolian cities): Dial 0 2372 1234567. The leading '0' is the national trunk prefix, followed by the NDC 2372 and the local number.
• International calls from abroad: Dial +976 2372 1234567 (or 976 2372 1234567 from a mobile phone). Replace the leading '0' with the country code +976.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan, Mongolia has not implemented overlay codes for Darkhan. The 2372 area code remains the sole geographic code for the city's fixed-line services. Subscriber numbers are typically 7 digits long, but some older lines may have 6 digits; in such cases, the national operator may require adding a leading digit to standardize to 7 digits. Always verify the exact number length with the local provider.

Caller Instructions

• Local callers: Use the 7-digit number without any prefix.
• Domestic callers outside Darkhan: Use the full national format: 0 2372 + subscriber number.
• International callers: Use the international format: +976 2372 + subscriber number. Ensure you have the correct country code (+976) and drop the trunk prefix '0'.

For example, a typical Darkhan fixed-line number might be +976 2372 1234567. This format is essential for routing calls correctly through Mongolia's PSTN and international gateways.
