From the United States, dial **011** to place an international call, then **237** for Cameroon, then the area code (drop any leading 0), followed by the local number. With Telvio you dial the same format — no prefix change needed.

## Exit codes by source country

The exit code depends on where YOU are calling from. On mobile phones and VoIP apps, use + instead.

| Calling from | Exit code | You dial |
| --- | --- | --- |
| United States / Canada | 011 | 011 237 ... |
| United Kingdom | 00 | 00 237 ... |
| Australia | 0011 | 0011 237 ... |
| Most of Europe | 00 | 00 237 ... |
| Japan | 010 | 010 237 ... |
| From a mobile / VoIP app | + | +237 ... |

## Cameroon phone number format

Country code +237

Example +237 2 22 23 45 67

## Common mistakes

- ✕ Using the wrong exit code. Each country has its own (US: 011, UK: 00). On mobile, just use +.
- ✕ Forgetting the country code +237. Without it, the call will fail or route locally.

## Country codes that get mistaken for +237

A wrong country code does not fail cleanly. It connects — to a stranger in another country — and it bills. These are the codes a caller most plausibly dials instead of +237 when calling Cameroon.

- +233GhanaOne digit away[Guide](https://telvio.app/how-to-call/ghana/)

- +267BotswanaOne digit away[Guide](https://telvio.app/how-to-call/botswana/)

The reliable habit is to store Cameroon numbers with the plus sign and the full code — +237 — rather than typing them each time. A number saved in full international form dials correctly from any country you happen to be in, and removes the whole class of mistake above.

## Calling out of Cameroon

To dial an international number from inside Cameroon, start with the exit code 00, then the destination country code, then the number without its own trunk prefix. The exit code belongs to the country you are calling FROM, not the one you are calling.

On a mobile, press and hold the 0 key until a plus sign appears and dial the number in full international form instead. The plus tells the network to work out the exit code itself, so the same saved number dials correctly whether you are at home or abroad — no need to remember 00 at all.

## Frequently asked questions

What is the country code for Cameroon?

The country code for Cameroon is +237. Dial this after your exit code (or use + on a mobile) before the local number.

How do I call Cameroon from the United States?

From a landline: dial 011 + 237 + the local number. From a mobile or a VoIP app like Telvio: dial +237 + the local number — the + works from any country without knowing its exit code.

Do I need to drop the leading 0 when calling Cameroon?

Cameroon does not use a trunk prefix, so you dial the local number exactly as-is after the country code.

What is the exit code to call Cameroon from my country?

The exit code depends on where you are calling FROM, not the destination. The US uses 011, the UK and most of Europe use 00, Australia uses 0011. On any mobile phone or VoIP app, you can use + instead.

Can I call Cameroon mobile phones internationally?

Yes. Dial the country code +237 followed by the mobile number. VoIP apps like Telvio make this easy — just enter the full number with country code.
