A Note on the Names of Areas of France

(Summarized from “Administrative divisions of France - Wikipedia, the free encyclopedia.htm”)

The French Republic consists of eighteen regions.

Region: A set of Departments

Department: A set of Arrondissments

Arrondissment: A set of Cantons

Canton: A set of Communes.

This simplified view is the hierarchical structure, but exceptions exist.

The Region of Ilę de France holds eight departments: Paris (75), Seine-et-Marne (77), Yvelines (78), Essone(91), Hauts-de-Seine (92), Seine-Saint-Denis (93), Val-de-Marne (94) and Val-d’Oise (95).

In 2014 I stayed at a hotel in Paris. The postal-codes in Paris take the form 75xxx.

In 2016 I stayed at a hotel in Poissy. Poissy is in the department of Yvelines (hence “St Quentin en Yvelines”). The postal-codes in Yvelines take the form 78xxx.
