The moving boxes are gone, but the address on your vehicle registration certificate still points to your old home. That is a separate administrative update from changing your details with a bank, insurer, or postal service. Start by checking the procedure for your specific registration certificate.
Prepare the details you will need
Have the vehicle registration certificate available and check that the vehicle’s registration information is legible. You will generally need to enter the new address and identify the vehicle and its registered holder. The official service will show the current supporting-document requirements for your situation.
If the vehicle is leased, belongs to a company, or has more than one relevant holder, check which person or organisation must make the request. Avoid guessing from a previous move: the process can depend on the details recorded for the vehicle and on the number of address changes already made.
Use the official procedure
Consult the address-change guidance on Service-Public.fr and use the official France Titres service to complete the procedure. Follow the instructions it gives for the updated certificate or any label, rather than relying on an old example. Keep a record of the submission so you can refer back to it if you need to check its status.
Check the guidance date
Administrative instructions and document requirements can change. Before submitting, check the last-updated date on the guide you are reading and confirm the current details with official French sources. Le Guide de l’Immatriculation is an independent editorial resource, not a government website.
