Telephone numbers in Vietnam

Land lines

Fixed line phone numbers in Vietnam follow the format Area Code + Phone Number. The area codes depend on the province and/or city.

To dial a number within the same province or city, only the phone number needs to be dialed.

When dialing from a different province/city, follow the format 0 + Area Code + Phone Number.

At the moment, area codes may have from 1 to 3 digits, while phone numbers from 5 to 8 digits.
