The French telephone numbering plan is not only used for metropolitan France but also for the French overseas departments and some overseas collectivities.
The plan uses a ten-digit closed numbering scheme, where the first two digits denote the area:
- 01 Île-de-France
- 02 Northwest France
- 03 Northeast France
- 04 Southeast France
- 05 Southwest France
- 06 and 07 Mobile phone services
- 08 Freephone (numéro vert) and shared-cost services.
- 09 Non-geographic number (used by Voice over IP services, formerly 087 numbers)
All geographic numbers are dialed in the ten-digit format, even for local calls.
When calling France from abroad, the leading zero should be omitted: for example, to call a number in Southwest France, one would dial +33 5 09 75 83 51.
French people usually state phone numbers as a sequence of five double-digit numbers, e.g., 0x xx xx xx xx (and not, for example, 0 xxx xxx xxx).
