France Postal Codes & Phone Area Query

French postal codes were introduced by La Poste in 1972, using a five-digit numeric format (e.g., 75001 for the 1st arrondissement of Paris, 13001 for the 1st arrondissement of Marseille). The first two digits usually represent the department (Département, such as 75 for Paris, 13 for Bouches-du-Rhône), while the last three digits precisely represent the delivery office, distribution area, or specific building (CEDEX).

The country prefix for French phone numbers is +33. Local landline numbers begin with 0, followed by a 1-digit area code and an 8-digit local number (10 digits in total; in international format without the leading 0, the length is 9 digits). The area codes are allocated as follows: 1 for Paris and Île-de-France, 2 for the Northwest, 3 for the Northeast, 4 for the Southeast, and 5 for the Southwest. Mobile numbers typically start with 06 or 07. We provide simulated test numbers complying with the telecom dialing rules of the respective regions on the details page.

Postal codes in France consist of 5 digits (e.g., 75001 for Paris 1st Arrondissement). The first two digits represent the department code (e.g., 75 for Paris), and the last three specify the delivery post office or sorting zone (including CEDEX).

French landline numbers consist of 10 digits (starting with '0'), which include a 1-digit zone code (1 for Paris/Île-de-France, 2-5 for other geographic zones). Mobile numbers start with 06 or 07 and are also 10 digits long.

To call France, dial '+33', followed by the national number dropping the leading '0'. For example, to call a Paris landline: +33 1 42 27 78 89; to call a mobile: +33 6 12 34 56 78.

No, postal codes and telephone area codes are independently planned and managed by different authorities (the postal service vs. the telecom authority), so their geographic boundaries do not align directly. One area code usually contains hundreds or thousands of postal codes.

The correct postal code is the core basis for modern logistics and automated postal sorting. Writing the correct postal code avoids misrouting, reduces sorting steps, shortens delivery times, and ensures precise delivery to specific blocks or buildings.
