How to Call Vietnam from Abroad

Follow these steps to dial a phone number in Vietnam from any other country. The process is the same whether you are calling a landline or a mobile number.

  1. 1
    Dial the international access code or +

    On a mobile phone, press and hold 0 to get the + symbol. From a landline, dial your country's exit code (00 from most of Europe, 011 from the US/Canada, 0011 from Australia). With Kinvo, simply type + in the dialer.

  2. 2
    Dial Vietnam's country code: 84

    After the + or exit code, enter 84. This routes your call to Vietnam's telephone network.

  3. 3
    Drop the trunk prefix (0) from the local number

    When a Vietnam number starts with 0 domestically, remove it when dialing internationally. The trunk prefix is only used for calls within Vietnam itself.

  4. 4
    Dial the remaining local number

    Enter the area code (if applicable) and the subscriber number. The complete international number should look like this: +84 91 234 56 78
