Mayotte Phone Number validator
How the phone number format works
- Format
- Mayotte phone number in national or international (+262) format
- Example
- +262639012345
Things to watch for
- Accepts national or international (E.164, e.g. +262...) 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 Mayotte phone number is 9 digits under the country code +262, shared with Réunion — mobile numbers typically start with the 639 block. Mayotte became France’s 101st and most recently created department in 2011, after residents voted repeatedly to stay tied to France rather than join the rest of the Comoros archipelago’s 1975 independence, and it remains the only EU territory with a Muslim-majority population.
How this validator works
Enter the number in national form (0639012345) or full international form (+262639012345); this tool checks the 9-digit length and leading-digit pattern against the shared +262 numbering plan using Google’s libphonenumber, entirely in your browser. Because Mayotte and Réunion draw from the same +262 code but use different leading mobile digits, this check confirms the number is valid somewhere in that plan — it can’t independently confirm which of the two islands issued it.
What a pass doesn’t tell you
A pass confirms the digits form a real number under the shared +262 plan — it doesn’t confirm the SIM is active or which island — Mayotte or Réunion — actually issued it.
Scope: catches a malformed digit or wrong-length entry before a Mayotte number reaches a form — not a substitute for a real lookup service.

phone number FAQ
When did Mayotte become part of France?
Mayotte became France's 101st department in 2011, the country's most recently created department, after residents voted repeatedly — most decisively in a 2009 referendum — to deepen ties with France rather than join the rest of the Comoros archipelago in independence.
Is Mayotte the only Muslim-majority part of the European Union?
Yes — Mayotte is widely cited as the only EU territory with a Muslim-majority population, a legacy of the wider Comoros archipelago's Islamic heritage, even as Mayotte itself remains constitutionally and legally part of France and the EU.
Does a valid check confirm a Mayotte number is currently active?
No. It only confirms the 9 digits match a real number under the shared +262 plan — not that the SIM is active, which needs a carrier-side lookup this free tool doesn't perform.
