Question: How do I call a +84 number? The number I want to call is +84 28 3829 xxxx.
Answer: +84 is the country code for Vietnam. To call +84:
- Dial your country’s exit code. ‘011’ for the United States and Canada, ’00’ for many South American and European countries. Dialing a ‘+’ symbol on a mobile phone will automatically dial the local exit code.
- Dial ’84’ for the country code to connect your call to the Vietnamese phone network.
- Dial the rest of the phone number. Do not dial any leading ‘0’ in the local telephone number.
As this phone number begins with area code ’28’, it appears to be for Ho Chi Minh City.
To call this phone number from a landline phone within Vietnam and Ho Chi Minh, dial 3829 xxxx. Do not dial Vietnamese exit code or the country code ’84’. Do not dial the trunk prefix ‘0’ or the area code ’28’.
To call this phone number from within Vietnam and outside the Ho Chi Minh metro region or from a mobile phone, dial 028-3829-xxxx. Include the leading ‘0’ and the area code ’28’. Do not include the exit code or the Vietnamese country code of ’84’.
To call this phone number from the U.S. or Canada, dial 011-84-28-3829-xxxx. Do not dial any leading ‘0’ in the local telephone number.
To call this phone number from China, South Korea, the Philippines, India, New Zealand, or the United Kingdom dial 00-84-28-3829-xxxx. Do not dial any leading ‘0’ in the local telephone number.

Question: I am calling a country with country with country code “0084” – I do not recognize this number – what country is it? The phone number I was given is “0084 24 3938 xxxx.”
Answer: The number you are trying to call looks like Vietnam. The phone number is likely in Hanoi.
“00” is an international exit code (the number used to access the international switchboard) for most European and many Asian countries. If ’00’ is dialed from a country that does not use that as its exit code (the U.S. and Canada use ‘011’, Australia uses ‘0011’, Japan uses ‘010’, many countries of the former U.S.S.R use ‘8’ – wait for the dial tone – ’10’), the call will not work.
“84” is the country code for Vietnam. It is the number that is dialed to reach Vietnam from the international switchboard.
The remainder of the number appears to be the format for a Vietnamese phone number. The ’24’ signifies the area code for Hanoi within the Vietnamese numbering system. The remainder of the phone number is eight numbers (two blocks of four digits).
