About French postal codes

A French postal code has 5 digits: the first two are the department number (75 for Paris, 13 for Bouches-du-Rhône...), the last three identify the commune or delivery office. The current format has been in use since 1972; large organisations also use CEDEX codes.

On lecodepostal.fr you can search by department, commune and street, or enter a postal code to find the matching commune. The data is updated regularly.
