Area Code 2562 – Undurkhaan city, Khentii

Overview of Mongolia's +976 2562 Geographic Code

The +976 2562 prefix is a geographic National Destination Code (NDC) assigned to the city of Undurkhaan (also spelled Öndörkhaan), the administrative center of Khentii Province in eastern Mongolia. This code is part of Mongolia's public switched telephone network (PSTN) and is used for fixed-line services within the city and its immediate surrounding areas. Undurkhaan is a regional hub with a population of approximately 20,000, serving as a commercial and administrative center for the province.

Geographic Coverage and Administrative Jurisdiction

The 2562 code covers the urban area of Undurkhaan and its suburban zones, which fall under the jurisdiction of the Khentii Provincial Governor's Office. The city is located on the Kherlen River, about 300 kilometers east of the national capital, Ulaanbaatar. The code is exclusively used for wireline (PSTN) connections, including traditional copper lines and, increasingly, fiber-to-the-home (FTTH) services. Mobile numbers in Mongolia are not assigned geographic codes; they use distinct prefixes such as 8, 9, or 5, and are not tied to a specific region.

Dialing Formats and Caller Instructions

To call a fixed-line number in Undurkhaan from within Mongolia, you must dial the trunk prefix '0' followed by the area code '2562' and the subscriber number. For example, if the local number is 12345, you would dial 0 2562 12345 from any other part of Mongolia. From outside Mongolia, callers must use the international access prefix (e.g., 00 from most countries) followed by the country code 976, then the area code without the leading '0', and the subscriber number: +976 2562 12345. When dialing locally within Undurkhaan, the area code may be omitted, but it is always required for calls from other regions or countries.

Numbering Plan and Overlay Considerations

Mongolia's numbering plan follows ITU-T E.164 recommendations. The national significant number (NSN) for fixed lines in Undurkhaan is eight digits: the area code '2562' (four digits) plus a four-digit subscriber number. There are currently no overlay codes in Undurkhaan; the 2562 code is unique to this area. However, as demand for fixed-line services grows, the Communications Regulatory Commission of Mongolia may introduce additional codes or renumbering, but no such changes are imminent.

PSTN Infrastructure and Service Providers

Fixed-line services in Undurkhaan are primarily provided by the state-owned incumbent, Mongolia Telecom (Mobicom's fixed-line subsidiary), and a few smaller licensed operators. These services are delivered over a mix of copper and fiber infrastructure, with VoIP (Voice over IP) increasingly used for long-distance and international calls. The PSTN network is fully digital and supports standard telephony features such as call waiting, call forwarding, and ADSL internet over the same line.
