## How to call Vietnam

| Calling from | Dial |
| --- | --- |
| A mobile phone, anywhere | `+84 912 345 678` |
| United States & Canada | `011 84 912 345 678` |
| UK, Europe & most countries | `00 84 912 345 678` |
| Australia | `0011 84 912 345 678` |

Inside Vietnam, numbers are written with the trunk prefix 0 (for example 0912 345 678). Drop that 0 when you dial from abroad.

## Calling abroad from Vietnam

To call another country from a Vietnam landline, start with the exit code **00**, then the destination country code. On a mobile phone, holding **0** to type **+** works everywhere and replaces the exit code.

## Missed call from +84?

If you don’t know anyone in Vietnam, be careful with short missed calls from international numbers. “One-ring” scams hope you call back a premium-rate line. Don’t return the call, don’t share codes sent by SMS, and block the number if it keeps calling. A genuine contact will usually leave a message or text.
