Area Code 1452 – Ulaangom city, Uvs

Geographic Coverage and Administrative Jurisdiction

The area code 1452 is a geographic National Destination Code (NDC) assigned to the city of Ulaangom, the administrative center of Uvs Province in western Mongolia. This code serves the urban area of Ulaangom and its immediate surrounding settlements within the Uvs aimag. As with all Mongolian geographic codes, 1452 is used for fixed-line PSTN services, connecting subscribers via the national copper and fiber infrastructure.

Dialing Formats and Number Structure

When calling a fixed line in Ulaangom from within Mongolia, subscribers must dial the trunk prefix 0, followed by the area code 1452 and the local subscriber number. The complete national significant number (NSN) length for Mongolian fixed lines is 8 digits, including the leading trunk prefix. Therefore, after dialing 0-1452, the local number typically consists of 4 digits (e.g., 0-1452-XXXX). For international callers, the format is +976 1452 XXXX, where +976 is the Mongolia country code and the leading trunk prefix is omitted.

Caller Instructions

• Local callers within Ulaangom: If your telephone line is also within the 1452 area, you may be able to dial only the local 4-digit number, depending on your operator’s configuration. However, to ensure reliable routing, it is recommended to dial the full national format: 0 1452 XXXX.
• Callers from other regions in Mongolia: Always dial 0 1452 XXXX from any mobile or fixed line outside the Uvs aimag.
• International callers: Dial your country’s international access prefix (e.g., 011 from the US/Canada, 00 from most European countries), then 976 1452 XXXX.

Overlay and Numbering Considerations

Mongolia’s numbering plan is administered by the Communications Regulatory Commission of Mongolia. As of the latest updates, there are no overlay codes for Ulaangom; the 1452 code remains exclusive to the Uvs province’s fixed network. However, with the ongoing migration toward VoIP and NGN (Next-Generation Networks), some operators may route calls over IP backbones, but the dialing format remains unchanged for end users. For emergency services, always dial the national emergency numbers (101, 102, 103) regardless of the area code.

For businesses in Ulaangom, it is essential to display the international format (+976 1452 XXXX) on websites and marketing materials to facilitate inbound calls from global clients. When registering for services that require a valid phone number, ensure you use the correct NDC to avoid misrouting.
