Frequently asked questions
What is the format of a French postal code?
A French postal code has five digits, for example 75001 for central Paris. The first two digits generally correspond to the département.
How do I find my postal code?
Type your street and house number into the search box and the exact code appears instantly. You can also browse by commune and street.
What is the difference between the postal code and the INSEE code?
The postal code routes mail for La Poste; the INSEE code officially identifies each commune. A commune can have several postal codes and vice versa. Both are shown on our commune pages.
How current is the data?
The site is regularly synchronised with the Base Adresse Nationale (BAN), the official French address database. The date of the last update is shown in the footer.
Can one street have several postcodes?
Yes. In big cities the code can change with the house number, and the arrondissements of Paris, Lyon and Marseille each have their own code - always check the exact number.
