Area Code 221 – Baganuur

Overview of Mongolia's +976 221 Geographic Code

The +976 221 country-code/area-code combination is assigned to the Baganuur district, a significant administrative and industrial hub located within the jurisdiction of Ulaanbaatar, the capital of Mongolia. Baganuur is one of the nine düüregs (districts) of Ulaanbaatar, situated approximately 130 kilometers east of the city center. The area is primarily known for its large open-pit coal mine, which is a major supplier of fuel for the capital's power plants. The 221 prefix is a geographic National Destination Code (NDC) within the Mongolian Numbering Plan, administered by the Communications Regulatory Commission of Mongolia.

Dialing Formats and Usage

To call a fixed-line subscriber in Baganuur from abroad, you must dial the international access prefix (e.g., 00 or +), followed by Mongolia's country code 976, then the area code 221, and finally the subscriber's 6-digit local number. The complete international format is: +976 221 XXXX XX (where X represents the local digits). For example, a typical Baganuur landline number could be dialed as +976 221 123456.

Domestic callers from other parts of Mongolia (outside the Baganuur area) should dial 0 221 XXXXXX when using a PSTN line, with the leading trunk prefix '0' used for national long-distance calls. However, if you are calling from a mobile phone within Mongolia, you may often omit the trunk prefix and dial 221 XXXXXX directly, depending on your operator's dialing plan. Local calls within Baganuur itself may be made using only the 6-digit subscriber number, without the area code, if the network supports local dialing.

Geographic Coverage and Administrative Details

The 221 code covers the entire Baganuur district, including its central town area and surrounding sub-districts (bags). Although Baganuur is administratively part of Ulaanbaatar, it has its own distinct numbering area due to its geographic separation from the main city. This means that callers from central Ulaanbaatar (which uses area codes 11, 21, etc.) must dial the trunk prefix '0' and then 221 to reach Baganuur, treating it as a long-distance call for billing purposes.

Overlays and Numbering Plan Considerations

Mongolia's numbering plan is structured with variable NDC lengths, and the 221 code is not overlaid with other codes. The number length for geographic codes in Mongolia is typically 8 digits (including the NDC), but Baganuur's local numbers are 6 digits, making the total length 9 digits when including the NDC. This is an exception to the standard 8-digit format, so it is crucial to verify the exact number of digits when dialing.

For international callers, it is important to note that Mongolia uses the E.164 standard, and the plus sign (+) replaces the international access code. Ensure you have the correct local number, as missing digits will result in a failed call. For further assistance, consult your telecom provider or the official Mongolian numbering plan resources.
