🇻🇳How to call Vietnam from the US

The number
Drop the 0
Drop the leading 0: Hanoi's 024 becomes +84 24, a mobile written 090 becomes +84 90. Vietnam changed every mobile prefix in 2018, so a number saved before then almost certainly needs its prefix updated rather than its formatting fixed.

Family calls, and a corridor where numbers were reissued recently enough that an old contact list is frequently wrong.
03Cost
What a minute costs
Which of those applies is read off the digits you type, so you are never asked to guess whether a Vietnam number is a landline or a mobile. Services that ask you to pick quote one of these prices and are wrong whenever the guess is.
Per minute in USD from a US caller ID, part of a minute counting as a full one. Rates last changed 18 August 2026. Everything we publish for Vietnam, or check one number.

05Questions
Common questions
How do I call Vietnam from the US?
Dial 011, then 84, then the Vietnam number. Drop the leading 0: Hanoi's 024 becomes +84 24, a mobile written 090 becomes +84 90. Vietnam changed every mobile prefix in 2018, so a number saved before then almost certainly needs its prefix updated rather than its formatting fixed. From a browser on Airlophone there is no exit code at all: you type the number starting +84 and the price for that exact number appears before it dials.
What is the country code for Vietnam?
+84. From the US you dial 011 first to leave the country, so the full string begins 011 84. From the UK and most of Europe the exit code is 00 instead, and from Australia it is 0011.
How much does it cost to call Vietnam?
On Airlophone it starts at $0.35 a minute, billed per minute with part of a minute counting as a full one. The exact price depends on the band: landline $0.35, mobile $0.35 per minute. The band is read from the digits of the number itself, so you are never asked to guess whether a number is a landline or a mobile. Calling the same number on a mobile carrier's international direct dial or while roaming is charged separately by that carrier and is normally a great deal more.
What is the best time to call Vietnam from the US?
Vietnam is on UTC+7 with no daylight saving, so it is 11 hours ahead of US Eastern in summer and 12 in winter. Evening in the US is the following morning in Ho Chi Minh City.
Do I need an app or a SIM card?
No. Airlophone runs in a browser tab, so there is nothing to install and no SIM to buy, and it works the same on a laptop you have borrowed. The person you call needs nothing either: the call arrives on the ordinary phone network, so their phone rings whether it is a landline or a mobile and whether or not they have internet.
