Vietnam Technical Information – In Details

Vietnam Voltage

The voltage in Vietnam is 127 V which makes it compatible with the 110 V voltage in the United States of America, Canada, and Japan.

127 V has an advantage over higher voltage such as the 230 V voltage that it is considered generally safer as it is less powerful. On the other hand, it costs more to transmit power to the end user using 127 V as copper lines must be thicker, hence lower voltages are generally used by wealthy countries.

Vietnam Electrical Frequency

The electrical frequency in Vietnam is 50 Hz.

Note that most household and electrical/electronic equipments nowadays support multiple frequencies, so generally, electrical frequency is not an issue compatibility wise.

Vietnam Plug/Socket Type(s)

The plugs used in Vietnam are A or C or G.

Plugs/sockets are usually an issue when it comes to traveling, so always make sure you travel with a universal plug adapter.

Vietnam DVD Region

Vietnam uses DVD Region 3.

DVD Region 3 is used in East Asia and South East Asia, such as Hong Kong, the Philippines, and South Korea.

Note that a region 3 DVD cannot play on a DVD player supporting another region. There are, however, some region free DVD players available that can be used to overcome this.

Vietnam Blu-ray Region

Vietnam uses Blu-ray Region A.

Blu-ray Region A is used in North/Central/South America, Japan, Taiwan, North Korea, South Korea, Hong Kong and Southeast Asia.

Theoretically, a region A Blu-ray disc should not play in Blu-ray disc players supporting another region. However, most Blu-ray discs are now region free (meaning they can work on any Blu-ray disc player), and most Blu-ray players are also region free. Hence, compatibility is rarely an issue (for now) when it comes to Blu-ray discs.

Vietnam GSM Freqency(ies)

Vietnam uses the GSM 900 GSM frequency.

When travelling, make sure that your phone supports the GSM frequency of the country you’re traveling to. Usually the supported GSM frequencies are printed on the box of your phone as well as its manual.
