Overview of Area Code 215 (Vietnam)

Area code 215 is the National Destination Code (NDC) assigned to the landline telephone network of Dien Bien Province, a mountainous region in northwestern Vietnam. This geographic code is used for fixed-line services within the province, covering the provincial capital Dien Bien Phu and its surrounding districts, including Muong Lay, Tuan Giao, and Dien Bien Dong. The code is allocated under Vietnam's national numbering plan, which follows ITU-T E.164 recommendations.

Dialing Formats

When calling a fixed-line number in Dien Bien from within Vietnam, subscribers must dial the trunk prefix 0, followed by the area code 215 and the subscriber's 7-digit local number. The complete national format is: 0-215-XXX-XXXX.

For international callers, the country code for Vietnam is +84. Therefore, the international dialing format becomes: +84-215-XXX-XXXX. Note that the leading trunk prefix '0' is omitted when dialing from abroad.

Example: A fixed-line number in Dien Bien Phu might be (0215) 3 850 123. From overseas, you would dial +84 215 3 850 123.

Geographic Coverage and Administration

Dien Bien Province shares borders with Laos and China, and its remote terrain historically posed challenges for telecommunications infrastructure. The 215 code is administered by the Vietnamese Ministry of Information and Communications and is serviced by major PSTN operators such as VNPT and Viettel. As a geographic code, it is tied to the physical location of the fixed-line connection, and numbers under this code are not portable to other provinces.

Caller Instructions

  • Local callers within Dien Bien can often dial the 7-digit subscriber number directly without the area code, depending on the local dialing plan. However, for clarity and to avoid errors, it is recommended to always use the full national format, especially when calling from mobile networks.
  • Callers from other provinces in Vietnam must dial: 0-215-XXX-XXXX.
  • International callers must dial: +84-215-XXX-XXXX.

As with all Vietnamese fixed-line numbers, calls to 215 numbers are typically charged at standard domestic or international rates, depending on the caller's location and service provider.
