Verified 11 October 2022 - Directorate for Legal and Administrative Information (Prime Minister)
Each vehicle registered since April 2009 has its own SIV number (in the form AB-123-CD). Vehicles registered before this date get this number when a change of situation occurs (moving, sale...)
The vehicle retains this number until it is destroyed, even if it changes ownership. Carte grise It is indicated on your registration plate.
The SIV is the registration system for vehicles on French territory.

The SIV number shall consist of alphanumeric characters on the model AB-123-CD:
Mopeds registered before 1 July 2015
In the case of a moped registered before 1er July 2015, the issue retains its special format. It consists of 1 to 2 letters, followed by 2 to 3 digits, followed by 1 letter, with a space between the blocks of letters and the block of digits.
