What country is country code “0084”?

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).
