A Vietnam number gives your business a local presence with country code +84. Inside Vietnam, callers dial the trunk prefix 0 before the area code. From abroad, callers dial +84 and drop the 0.
Number types in Vietnam
- Local numbersGeographic numbers with a city or regional area code. Customers see a familiar local number and call you at local rates.
- National numbersNon-geographic numbers that work nationwide without tying you to one city — ideal for a single number across the whole country.
- Mobile numbersNumbers from mobile ranges, for services that need a mobile-looking number. SMS capability depends on the range.
- Toll-free numbersFree for your callers from most networks. You cover the inbound cost, which lowers the barrier for sales and support calls.
