To write French phone numbers correctly, use the national format 0X XX XX XX XX for domestic calls and the international format +33 X XX XX XX XX when dialing from abroad. Mastering this pattern ensures you avoid dialing errors and successfully connect with anyone in France.
How to write French phone numbers in national format
Inside France, every phone number is written as a 10-digit sequence starting with a trunk code of 0, followed by a two-digit area or operator code, then six more digits grouped in pairs. The standard domestic pattern is 0X XX XX XX XX. For example, a Paris number is written as 01 23 45 67 89. The paired grouping makes the number easier to read and verify, and you must include the leading 0 whenever dialing from within France.
How to write French phone numbers in international format
When dialing a French number from another country, replace the leading 0 with +33, France’s country code. The international pattern becomes +33 X XX XX XX XX, where the X is the area or operator code without its original 0. Using the same example, 01 23 45 67 89 becomes +33 1 23 45 67 89. This format works for all calls from outside France and is essential for understanding international calling codes and dialing. When dialing an international French phone number, it may require additional digits or prefixes depending on the specific country you are calling from. Be sure to check the international dialing instructions or contact your service provider for accurate information. If you are writing a French phone number for someone outside of France to call, it is important to include the international access code for your country.
Landline and mobile numbers follow the same rules
Both landline and mobile numbers use the identical 10-digit domestic format and the identical +33 international format. No separate rules exist for writing mobile numbers. A mobile number such as 06 12 34 56 78 is written domestically as 06 12 34 56 78 and internationally as +33 6 12 34 56 78. The first two digits after the trunk code or country code indicate the operator or region, but the formatting pattern is the same for every type of line.
How to automatically format numbers on iPhone
Apple provides a setting in iCloud Contacts that can automatically format phone numbers with hyphens and other symbols. To enable it:
- Open iCloud Contacts on a computer.
- In the sidebar, click the Action pop-up menu and choose Preferences.
- From the Address Layout menu, select France (or the country whose format you want).
- Check the box “Automatically format phone numbers” if you want Contacts to add hyphens and other symbols automatically.
If you need to enter numbers in more than one format, do not select this option. Apple’s documentation does not specify a France-specific iPhone menu path, supported iPhone models, or iOS version limits for this feature.
A note on Android formatting
No official Android help page documents a France-specific auto-formatting feature for phone numbers. Because no verified instructions exist, you cannot rely on a built-in Android setting to automatically rewrite French numbers. Manually enter numbers using the 0X XX XX XX XX or +33 X XX XX XX XX pattern to ensure accuracy.
Additional Tips for Writing French Phone Numbers
France follows a 24-hour clock format. If you need to specify a time in relation to a French phone number, make sure to use the appropriate format to avoid any confusion.
Frequently Asked Questions
Should I use spaces or hyphens when writing a French phone number?
Spaces are the standard separator in the domestic format (0X XX XX XX XX). Hyphens are not used in official French conventions. For international format, a single space after the country code is typical, followed by spaces between digit pairs.
What do the first two digits of a French phone number mean?
The first two digits after the trunk code 0 (or after +33) indicate the geographic area or mobile operator. For example, 01 is the Paris region, 02 is northwest France, and 06 or 07 are mobile numbers. This two-digit code is not an area code in the sense of a separate prefix; it is part of the 10-digit number.
Do I need to dial a different number if I call a French mobile from outside France?
No. Both landline and mobile numbers use the same international format: +33 followed by the remaining nine digits (without the leading 0). The only difference is the operator code (6 or 7 for mobile).
Can I drop the spaces when writing a French number for an online form?
Yes. Many forms accept the digits without spaces, such as 0123456789 for domestic or 33123456789 for international (without the +). However, the paired grouping with spaces is the standard written convention and improves readability.
What is the emergency number format in France?
Emergency numbers like 112 (general emergency) or 17 (police) are short codes, not 10-digit numbers. They do not follow the national or international formatting rules described above and are dialed exactly as written, without a country code.
