How to read a Vietnam phone number
A Vietnam number is +84 followed by 10 digits. Knowing which of those digits mark a mobile is what tells you what the call will cost before you place it.
Inside Vietnam, numbers are dialled with a leading 0. Drop it when calling from abroad — keeping it is the single most common reason an international call fails.
Mobile prefixes
Landline prefixes
Prefix ranges still identify a line as mobile or fixed even where a number has been ported between operators, because the mobile and fixed blocks are separate and numbers do not move between them. Operator identification from a prefix, by contrast, stopped being reliable once portability arrived.

Other Asian destinations, cheapest first
Rates vary by more than a factor of ten inside a single region, because each one is set by what the operator at the far end charges to accept the call. Taiwan is currently the cheapest place we publish a rate for near Vietnam.

All toolsFrequently asked questions
What is the country code for Vietnam?
The country code for Vietnam is +84. Dial this after the exit code (or use + on a mobile).
What are the area codes for Vietnam?
Vietnam has 3 city area codes listed on this page, including Ho Chi Minh City 28, Hanoi 24, Da Nang 236. Dial the country code first, then the area code without its trunk prefix, then the local number. The table above gives the full dial string for every city.
What does a Vietnam phone number look like?
A Vietnam number is written as +84 24 1234 5678: the country code +84 followed by 10 digits. That total is fixed by the national numbering plan, so a number with one digit missing is a typo rather than a shorter valid number.
How can I tell if a Vietnam number is a mobile?
By its leading digits. In Vietnam, a national number of 10 digits beginning with 3, 5, 7, 8, 9 is a mobile. That still works after a number has been ported between operators, because mobile and fixed-line blocks are separate ranges and numbers do not move between them.
Do I need to drop the leading 0 when calling Vietnam?
Yes. Vietnam uses 0 as a trunk prefix for domestic calls. When dialing internationally, drop the leading 0 from the local number.
How much does it cost to call Vietnam?
Telvio charges $0.65/min to Vietnam landlines and $0.65/min to mobiles. Billing is per second with no connection fees, so you pay only for the seconds you talk.
