🇻🇳Vietnam Country Code +84

The country calling code for Vietnam is +84. Put it in front of the number when you call Vietnam from another country, and leave out the 0 that starts numbers inside Vietnam.

Dial your country's international access code (or press + on a mobile phone), then 84, then the number without its leading 0. For example, 0912 345 678 inside Vietnam is dialled as +84 912 345 678 from abroad.

Only when you call from inside Vietnam. The 0 is the trunk prefix, used for calls within the country. From abroad you leave it out: 0912 345 678 becomes +84 912 345 678.

Most phone numbers in Vietnam have 9 or 10 digits after the country code: mobile numbers have 9 and landlines 10. Some special-service numbers (toll-free, premium-rate) are shorter or longer.

To call another country from Vietnam, dial 00, then the country code you are calling, then the number. On a mobile phone you can press + instead of 00.
