+84 explained
The Vietnam country code, 84, is what you dial before a Vietnam number when you call from abroad. It is also known as the Vietnam dialing code, Vietnam calling code, or Vietnam phone code. In the Vietnam phone number format, +84 comes first, then the area code, such as 28 for Ho Chi Minh City, then the local number.

Vietnam phone number types
The first digits of a Vietnam number tell you what kind of number it is: a landline, a mobile, a free number, or one that costs more to call. Here is a sample of each type of Vietnam phone number, as dialed inside Vietnam and from abroad.

Questions about +84
Which country is +84?
+84, or country code 84, belongs to Vietnam. It shares its code with no other country.
What is +84?
+84 is the part you dial before a Vietnamese number when you call from another country. It replaces the first 0 of the number: Hanoi's 024 1234 5678 becomes +84 24 1234 5678.
What is the difference between +84 and 0084?
The + stands for your exit code. 00 is the exit code in Vietnam and most of the world, so 0084 and +84 reach the same number there. From the US and Canada, dial 011 84 instead.
Do I drop the 0 after +84?
Yes. The 0 is Vietnam's trunk prefix and works only inside the country. For Hanoi, dial +84 24, not +84 024.
Can I text a +84 number?
Yes. Write the number as +84 without its first 0. A Ho Chi Minh City number starting 028 becomes +84 28, and your phone sends the text abroad at your carrier's international rate.
How much does it cost to call Vietnam?
A call to a Vietnamese mobile costs more than a call to a landline. The dialer on this page shows the exact price of the number you enter before you call.
Is VN the same as +84?
No. VN is the ISO code of Vietnam, used in forms and address fields. The number you dial is +84.
