About Cameroon Calling Code

Cameroon's international dialing code is +237. This code is assigned by the International Telecommunication Union (ITU) and must be dialed before the local phone number when calling Cameroon from another country. Cameroon is located in Africa.

Country calling codes (also known as ISD codes or dialing codes) are telephone numbering plan prefixes defined by ITU-T standards E.123 and E.164. Each country is assigned one or more unique prefixes to facilitate international direct dialing.

Where the +237 Calling Code Is Used

The country code +237 is assigned to Cameroon, located in Middle Africa, with the capital Yaounde. This code is part of the international telephony numbering plan and is used for all calls made to Cameroon from outside the country.

When you see a phone number written as +237 ..., the +237 prefix tells your telephone network to route the call to Cameroon's national telephone network. After the country code, you dial the local area code (dropping any leading 0) and the subscriber number. The same format applies whether you are calling a landline or a mobile phone.

Country codes are allocated by the International Telecommunication Union (ITU-T Recommendation E.164) and are grouped by geographic region. Calling codes starting with 2 are generally assigned to the region around Cameroon, in Middle Africa. When a phone number is stored internationally, the leading zeros of the domestic area code are omitted after the country code โ€” this is why you will often see numbers written as +237 followed directly by the area code and number.

Cameroon Phone Number Formats

Phone numbers in Cameroon follow the ITU E.164 international format: country code + area code + subscriber number. Below is the general structure used for both landlines and mobile numbers.

๐Ÿ“ฑ Number Structure

  • International format: +237 [area code] [subscriber number]
  • From abroad: exit code + +237 + local number (drop the trunk prefix 0)
  • Within Cameroon: dial the local number directly

Most countries use a closed or open telephone numbering plan. In an open plan, the length of local numbers varies and the trunk prefix (usually 0) is dropped when dialing internationally. In a closed plan, all national numbers have a fixed length regardless of area. When dialing Cameroon from abroad, always replace the leading trunk zero with the country code +237.

Time Zone in Cameroon

Cameroon is in the Africa/Douala time zone, which is UTC+01:00 relative to Coordinated Universal Time (UTC). If you are calling from a different time zone, remember to account for the time difference when scheduling your international call.

When planning a call to Cameroon, the time difference matters: a good time to reach businesses in Yaounde, the capital, during their working hours may be early morning or late evening in your own time zone. Many international callers use the UTC offset as a quick reference to avoid calling in the middle of the night.

Some countries observe daylight saving time (DST), which shifts the local clock by one hour during summer months. If Cameroon uses DST, the effective offset changes twice a year โ€” check the current UTC offset before dialing if your call is time-sensitive. For most purposes, however, the standard offset shown above is sufficient.

Example: Calling Cameroon Numbers in Practice

Here is how a typical call to Cameroon works, depending on where you are calling from:

๐ŸŒ From the United States or Canada

  1. Dial the US/Canada exit code 011
  2. Dial the Cameroon country code +237
  3. Dial the local number (area code + subscriber number, without the trunk prefix 0)

Example: 011 +237 [area code] [number]

๐ŸŒ From the United Kingdom or Europe

  1. Dial the international access code 00 (or use the + symbol on mobile)
  2. Dial the Cameroon country code +237
  3. Dial the local number

Example: 00 +237 [area code] [number], or +237 [area code] [number] from any mobile phone

If the number you are calling has a domestic trunk prefix (often 0) in front of the area code, omit it when dialing from abroad. The country code +237 replaces the trunk prefix entirely.
