Area Code 275 – Ben Tre province

Geographic Overview

Area code 275 is a geographic National Destination Code (NDC) assigned to the Ben Tre province in the Socialist Republic of Vietnam. Ben Tre is situated in the Mekong Delta region, approximately 85 kilometers southeast of Ho Chi Minh City. The province is known for its extensive river network, coconut production, and growing tourism sector. The administrative capital is Ben Tre City, which serves as the primary economic and telecommunications hub for the province.

Dialing Formats

For domestic callers within Vietnam, the local number format is 0275 XXX XXXX. When dialing from a landline or mobile phone within the country, callers must include the trunk prefix 0 followed by the area code and subscriber number. For example, to call a landline in Ben Tre City, one would dial 0275 123 4567.

For international callers, the format changes to +84 275 XXX XXXX, where +84 is the country calling code for Vietnam, and the leading 0 is omitted. Thus, an international caller would dial +84 275 123 4567 to reach the same subscriber.

Geographic Coverage and Administration

The 275 area code covers all landline telephone exchanges within Ben Tre province, including Ben Tre City and the districts of Ba Tri, Binh Dai, Chau Thanh, Cho Lach, Giong Trom, Mo Cay Bac, Mo Cay Nam, and Thanh Phu. The code is administered by the Vietnam Telecommunications Authority under the Ministry of Information and Communications, in accordance with ITU-T E.164 recommendations.

Numbering and Overlays

Subscriber numbers under the 275 code are seven digits long, resulting in a total capacity of up to 10 million numbers. As of the latest updates, no overlay codes have been introduced for Ben Tre province. This means that local calls within the province can be made using only the seven-digit subscriber number, without the area code, when dialing from a landline within the same geographic area. However, for clarity and to avoid misdialing, it is recommended to use the full national format, especially when calling from mobile networks.

Caller Instructions

For local callers within Ben Tre: If you are calling from a landline within the same province, you may dial only the seven-digit subscriber number. However, if you are calling from a mobile phone or from outside the province, you must dial the full national number: 0275 XXX XXXX.

For international callers: Always use the international format: +84 275 XXX XXXX. Ensure you replace the leading zero with the country code. For example, a caller from the United States would dial 011 84 275 XXX XXXX (or +84 from a mobile phone).

Important Considerations

Since May 2017, Vietnam has implemented a new numbering plan, and all fixed-line numbers, including those in Ben Tre, have been standardized to 10 digits (including the trunk prefix). When storing numbers in your contacts, always include the area code to ensure proper routing. For VoIP and internet-based calling services, the same international format applies, but be aware that some services may require a different dialing prefix depending on the country of origin.
