What +33 means

+33 is the country calling code for France. The same code is written 0033 when you dial out from most of Europe, Africa and Asia, and 011 33 from the US and Canada. All three reach the same place: only the exit code in front of it changes. Whichever one you use, the national trunk 0 is dropped once the country code is in front.

Mobile numbers

Mobiles start with 6 or 7 (written 06 or 07 nationally).

Converting to E.164

Take the number as written locally (06 12 34 56 78), drop the leading 0, then prefix +33. The result is +33612345678: no spaces, no dashes, no parentheses. Store that, and format for display only when you show it to a human.

Why not do it with a regex

A pattern that matches France numbers today breaks the moment a new mobile range is allocated, and it cannot tell you whether the number is actually assigned. The tool above runs the same numbering-plan engine as our phone validation API, so it also reports line type and region rather than just shape.

A prefix tells you the range a number was issued from, not which network holds it today — numbers move between operators. For the current carrier you need a live lookup, which is what our phone API returns.

France is a closed ten-digit plan, and 01 is a region not a city

Every French number is ten digits at home, including the leading 0: 01 is Île-de-France, not 'Paris' in the sense of a city code, and 04 covers Lyon, Marseille and Nice together. Overseas departments use other 0x ranges. Splitting a French number to extract a city from the first two digits is guessing for most of the country.

Questions

France phone numbers, answered

What country is +33?

+33 is France. Written 0033 from most of Europe and 011 33 from the US and Canada. Drop the leading 0: 06 12 34 56 78 locally is +33612345678 internationally.

How many digits is a French phone number?

Nine after the +33, ten as written at home with the leading 0. That total is fixed: landline, mobile and non-geographic numbers are all the same length.

Do French mobiles start with 06 or 07?

Yes. 06 and 07 are the mobile ranges. 09 is non-geographic (often VoIP), 08 is special-rate, and 01 to 05 are geographic. In international form every one of these loses its leading 0.

That is how a France number is written. Whether a whole list is worth dialling is the free call list cleaner, or check one number on the spam phone checker.
