Description -- Arrondissements
The city of Paris is divided into twenty arrondissements municipaux, administrative districts, more simply referred to as arrondissements (). These are not to be confused with departmental arrondissements, which subdivide the 100 French départements. The word arrondissement, when applied to Paris, refers almost always to the municipal arrondissements listed below. The number of the arrondissement is indicated by the last two digits in most Parisian postal codes (75001 up to 75020).
