France uses five-digit numeric postal codes.They were updated to use the current 5 digits system in 1972. e.g：
3 3 3 8 0
the first two digits representing the département in which the city is located. The last three digits identify a more precise location.000 being in general reserved for the préfecture. However, in Paris, Lyon and Marseille, the last two digits indicate the arrondissement. For example, 80000 corresponds to Amiens, which is the préfecture of the Somme or département 80, while 69008 corresponds to the 8th arrondissement of Lyon.

A regular postcode always ends with a 0, with the notable exception of Paris, Lyon and Marseille - see below - and the Overseas Départements and Territories. Postcodes not ending with a 0 may indicate a special code, known as CEDEX (see below), or newest postcodes.
In Paris, Lyon and Marseille, the last two digits of the postal code indicate the arrondissement. Prior to 1972, an address in the eighth arrondissement in Paris, would be written as:
- 8 rue Chambiges
- Paris 8e
This number was incorporated into the postal code as:
- 8 rue Chambiges
- 75008 Paris
An exception to this rule is the XVIe arrondissement of Paris, which has two postal codes, 75016 (south) and 75116 (north).
In each département, the préfecture (main city) has a postal code ending with 000, for example Bourges in Cher (department):
- 15 avenue du Général Leclerc
- 18000 Bourges
The more important the city, the simpler the postal code. The sous-préfectures are generally recognized by using a XXX00 postcode. Here is for example the postal code of a small village, Lépaud in Creuse:
- 16 grande rue
- 23170 Lépaud
And the postal code of Mortagne-au-Perche, sous-préfecture of the Département de l'Orne:
- 4 rue des Quinze Fusillés
- 61400 Mortagne-au-Perche
It is not rare that many adjacent villages share the same postal code, which is primarily associated with a bigger post office, e.g.: 64150 can correspond to Abidos, Bésingrand, Lagor, Lahourcade, Mourenx, Noguère, Os Marsillon, Pardies, Sauvelade and Vielleségure.
Overseas Départements and Territories use 3-digit codes starting with : 971 (Guadeloupe), 972 (Martinique), 973 (French Guiana), 974 (Réunion), 975 (Saint-Pierre and Miquelon), 976 (Mayotte), 984 (French Southern and Antarctic Lands), 986 (Wallis and Futuna), 987 (French Polynesia), 988 (New Caledonia). In March 2008 La Poste proposed allotting 977 to Saint Barthélemy and 978 to Saint Martin (France) due to their new status as Overseas collectivity.
In this case, the last zero is dropped so as to keep the 5-digit format. This is why the regular postcodes for these do not end with 0 except for the préfecture or sous-préfecture, for example:
- Maison du Port
- 97100 Basse-Terre
- 4 boulevard du Général de Gaulle
- 97320 Saint-Laurent du Maroni
- 193 RN2
- 97439 Sainte-Rose
There is also a system known as CEDEX, Courrier d'Entreprise à Distribution EXceptionnelle ("special mail distribution for companies"), designed for recipients of large volumes of mail. A postal code is allocated to each large organisation or to post office box holders, ending in three unique digits, for example:
- 12 rue de Broquedis
- 64205 Biarritz CEDEX
CEDEX should always be written in capitals. It may be followed by a number, if the town has more than one post office, or if it is split into arrondissements.
Ordinary deliveries would be addressed to:
- 12 rue de Broquedis
- 64200 Biarritz
It is acceptable to include a boîte postale (post office box) number as well as the street address in CEDEX addresses.
The French postal code system is also used in Monaco as if it were a French département numbered 98. However the destination country that has to be indicated, when sending a letter from outside the country, is "Monaco" and not "France".
- 12 avenue de la Costa
- 98000 Monaco
- 23 Avenue Prince Héréditaire Albert
- 98025 Monaco CEDEX
