Cameroon Phone Number validator
How the phone number format works
- Format
- Cameroon phone number in national or international (+237) format
- Example
- +237671234567
Things to watch for
- Accepts national or international (E.164, e.g. +237...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Cameroonian mobile number is nine digits, opening with 6 — covering the 65 to 69 range — and followed by seven more digits, for example 671 234 567. Since a 2014 numbering reform lengthened every Cameroonian number and dropped the old trunk-0 convention, the same nine digits are used both at home and abroad: +237671234567 is simply the country code placed in front, with nothing stripped out first.
How this validator works
Enter the number as it’s commonly written (671234567) or with the country code attached (+237671234567); this tool checks the nine-digit length and the 6x mobile prefix against Cameroon’s current numbering plan using Google’s libphonenumber, entirely in your browser. Because there’s no trunk 0 to remove here, the validator’s most frequent catch is an extra 0 added out of habit — a pattern more common in neighboring countries that still use one — which pushes the total past nine digits and fails.
What a pass doesn’t tell you
A pass confirms the digits are shaped like a genuine Cameroonian mobile number — it says nothing about whether the SIM behind it is currently active or reachable.
Scope: use this to catch a wrong prefix or a habit-driven extra 0 before a Cameroonian number reaches a form or SMS platform — not as proof it’s in service today.

phone number FAQ
Does a Cameroonian mobile number need a leading 0 stripped for +237?
No. Cameroon's 2014 numbering reform added a digit to every number and retired the old trunk-0 dialing habit at the same time, so a mobile number is written and dialed as the same nine digits both locally and internationally — 671234567 becomes +237671234567 with nothing removed.
What does a valid Cameroonian mobile prefix look like?
It opens with 6, covering the 65 through 69 range, followed by seven more digits. Numbers opening with 2 belong to the separate fixed-line and older mobile numbering that predates the 2014 expansion.
Does a valid check confirm the Cameroonian SIM is switched on?
No. It only confirms the nine digits fit a real pattern under Cameroon's current numbering plan — it can't tell you whether that SIM is currently active, which needs a network-side check this tool doesn't perform.
