Since January 2009, all new vehicles on the road in France are issued with a new type of registration number. Second-hand vehicles in France also get a new registration number when it changes hand.
The “old” registration number used to have 4 digits, 2 or 3 letters and the department number. In the Côtes d’Armor in Brittany our département number is 22. The front plate was black and the back one yellow.
The new plates (plaques d'immatriculation) are white and similar at the front and back of the car. It has 7 characters: 2 letters, 3 digits and 2 more letters.
If you wish your department to be added on your plates, it will be on the right side. It is optional though.
