## How to call Cameroon

| Calling from | Dial |
| --- | --- |
| A mobile phone, anywhere | `+237 6 71 23 45 67` |
| United States & Canada | `011 237 6 71 23 45 67` |
| UK, Europe & most countries | `00 237 6 71 23 45 67` |
| Australia | `0011 237 6 71 23 45 67` |
| Inside Cameroon | `6 71 23 45 67` |

Cameroon does not use a trunk prefix, so the number you dial at home is the same one you dial after +237.

## Missed call from +237?

If you don’t know anyone in Cameroon, 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.
