Area Code 261 – Dak Nong province

Overview of Area Code +84 261

Area code 261 is the National Destination Code (NDC) for the Dak Nong province in Vietnam's Central Highlands region. When dialing from abroad, the full international number format is +84 261 XXX XXXX, where +84 is Vietnam's country calling code (per ITU-T E.164), 261 is the geographic area code, and the remaining seven digits represent the subscriber's local number. Within Vietnam, callers must use the trunk prefix 0 before the area code, resulting in the national dialing format 0261 XXX XXXX.

Geographic Coverage and Administrative Jurisdiction

Dak Nong province is located in the Central Highlands, bordered by Dak Lak to the north, Lam Dong to the south, and Cambodia to the west. The provincial capital is Gia Nghia, and other major towns include Dak Mil, Dak R'Lap, and Dak Song. The 261 area code serves all landline and fixed-line subscribers within the province, including both urban and rural districts. As a geographic code, it is assigned to the PSTN (Public Switched Telephone Network) and is administered by the Vietnam Telecommunications Authority under the Ministry of Information and Communications.

Dialing Formats and Caller Instructions

• Local calls within Dak Nong: For calls between landlines within the same province, dial the 7-digit subscriber number directly (e.g., XXX XXXX). However, some inter-district calls may require the full national format; check with your service provider.
• National long-distance calls from other Vietnamese provinces: Dial 0261 followed by the 7-digit subscriber number (e.g., 0261 XXX XXXX).
• International calls from abroad: Dial your country's exit code (e.g., 00, 011) then 84 261 XXX XXXX (e.g., +84 261 123 4567).

Overlay and Numbering Considerations

As of the latest ITU-T and national numbering plan updates, there is no overlay code for Dak Nong; the 261 code is exclusive to the province. Subscriber numbers are seven digits long, and the total length of a national significant number (NSN) is 10 digits (including the leading 0). The Vietnamese numbering plan is closed, meaning the trunk prefix 0 is always used for national calls. For international callers, the leading 0 is omitted.

Practical Examples

If you are calling a landline in Gia Nghia from Hanoi, you would dial: 0261 XXX XXXX. From the United States, you would dial: 011 84 261 XXX XXXX. From a mobile phone abroad, simply use +84 261 XXX XXXX. Always verify the number with your contact, as mobile numbers in Vietnam do not use geographic area codes and are prefixed with 3, 5, 7, 8, or 9.
