Administrative divisions:

France is divided into 26 administrative regions. 22 are in metropolitan France (21 are on the continental part of metropolitan France; one is the territorial collectivity of Corsica) , and four are overseas regions. The regions are further subdivided into 100 departments which are numbered (mainly alphabetically). This number is used in postal codes and vehicle number plates amongst others. The 100 departments are subdivided into 341 arrondissements which are, in turn, subdivided into 4,032 cantons. These cantons are then divided into 36,680 communes, which are municipalities with an elected municipal council.
