Area Code 254 – Ba Ria Vung Tau province

Geographic Coverage and Administrative Jurisdiction

The area code 254 is a geographic National Destination Code (NDC) assigned to the province of Ba Ria – Vung Tau in Vietnam. This province is located in the Southeast region of the country, along the coast of the South China Sea. It includes the provincial capital, Vung Tau City, as well as Ba Ria City and the surrounding districts. The code covers both fixed-line PSTN subscribers and, in some cases, fixed wireless local loop services within the province.

Dialing Formats and Caller Instructions

For callers placing a call from within Vietnam to a fixed line in Ba Ria – Vung Tau, the national trunk prefix 0 is used, followed by the area code 254 and the subscriber number. The complete national format is 0 254 XXX XXXX (where X represents the subscriber digits). For example, a local call from Ho Chi Minh City to a number in Vung Tau would be dialed as 0 254 123 4567.

For international callers, the Vietnamese country code +84 replaces the leading zero. The international format becomes +84 254 XXX XXXX. Thus, a caller from the United States would dial 011 84 254 123 4567, while a caller from the United Kingdom would dial 00 84 254 123 4567.

Local Dialing and Overlay Considerations

Within the same area code, local calls may be placed using only the subscriber number, depending on the operator's network configuration. However, it is always safe to use the full national format to avoid misdialing. As of the latest numbering plan updates, there is no overlay code for Ba Ria – Vung Tau; the area code 254 remains the sole geographic code for the province. This means that all fixed-line numbers in the province share the same trunk prefix and area code, simplifying dialing procedures.

Regulatory and Technical Notes

The assignment of area code 254 is managed by the Vietnam Telecommunications Authority under the Ministry of Information and Communications, in accordance with ITU-T E.164 recommendations. The subscriber number length for geographic codes in Vietnam is typically between 5 and 7 digits, but for Ba Ria – Vung Tau, the standard is 7 digits after the area code, making the total national significant number (NSN) 10 digits (including the leading 0). This structure ensures efficient routing and numbering capacity for the province's growing telecommunications needs.

For businesses and individuals, it is important to note that calls to geographic numbers are generally charged at standard national rates, which may vary depending on the operator and the time of day. International callers should consult their service provider for applicable international tariffs.
