Changing the address on a registration certificate is a legal obligation to be carried out within a month following a move. Norauto, as a service provider authorized by the ANTS (National Agency for Secure Titles), offers assistance for this process. The principle remains simple: submit the required documents through an authorized professional rather than navigating the official online service alone.
Label or new title: what the process actually produces
A rarely detailed point concerns the concrete result of the request. Depending on the format of your registration number, the administrative processing differs.
For vehicles registered in the current SIV format (plates XX-123-XX), changing the address generates a simple adhesive label to be affixed to the registration certificate. The plate number does not change, and the original document remains valid.
For vehicles still under the old registration format (123 XX 50), the procedure results in the issuance of a new complete title. The vehicle then switches to the SIV system with a new number, which also implies a change of license plates.
This distinction has a direct impact on the cost and processing time. Going through a Norauto center or directly through the ANTS does not change this rule: it is the registration format that determines the outcome. The Norauto address change procedure follows exactly the same administrative circuit as the official online service, since authorized providers submit the file to the SIV.
Cost of changing the address on the registration certificate: free under certain conditions
The address change is free for the first three declarations on a certificate in SIV format. From the fourth change, a processing fee of 2.76 euros applies.
For the old plate formats, this fee of 2.76 euros is due from the first request, as the processing involves the creation of a new title.
At Norauto, service fees may be added to this administrative cost. The provider charges for assistance in compiling and submitting the file. This rate varies by center. Going directly through the ANTS remains the only completely free option (except for the fourth change), but it requires mastering the online process and having access to FranceConnect or the confidential code on the certificate.
Required documents for a complete file at Norauto
The list of supporting documents is the same regardless of the chosen channel (ANTS, Norauto, or another authorized provider). An incomplete file systematically blocks processing.
- The original registration certificate (carte grise), or alternatively a loss declaration if the document was lost during the move
- A proof of residence less than six months old (utility bill, tax notice, rent receipt)
- A valid identification document of the holder
- The Cerfa form for the address change request, often pre-filled by the provider in the center
If the registration certificate was lost during the move, the request for a duplicate and the address change can be processed simultaneously. In this case, a new certificate is issued directly with the new address.
Case of co-holders
When the vehicle is registered in the name of multiple people, each co-holder must provide proof of residence. If the co-holders do not reside at the same address after the move, the situation may require a broader modification of the certificate.
Address change without moving: municipal merger and street renaming
The obligation to update is not limited to moves. A municipal merger or street name change decided by the municipality renders the address on the certificate obsolete, even without changing residence.
In these cases, the process is the same: online declaration or through an authorized provider, within one month after the official notification of the change. Failure to comply with this deadline exposes one to a fine of up to 135 euros in the event of a roadside check.
These situations regularly affect motorists who are unaware that their administrative address has changed. Checking the consistency between the address on the certificate and that recognized by the municipality remains a useful reflex after any territorial modification.
ANTS, Norauto, or online service: which channel to choose to declare your new address
Three options coexist to carry out this process, each with its constraints.
- The official online service of the ANTS (via FranceConnect or confidential code): free, accessible online, but requires digital autonomy and sometimes variable processing times
- Going through an authorized Norauto center: in-person assistance, immediate verification of the file, but service fees charged in addition
- The online service “I change my contact details” on Service-Public.fr, which can submit the request to the SIV if the file is eligible, otherwise redirects to the ANTS
The choice depends on the level of comfort with digital tools and the complexity of the file. A simple change on a vehicle in SIV format, with all documents in hand, can be processed in a few minutes on the ANTS. A file involving an old format, a co-holder, or a lost registration certificate benefits from being accompanied by a professional.
Regardless of the channel, the legal deadline of one month runs from the effective date of the move or the notification of address change by the municipality. A provisional registration certificate (CPI) can be issued while waiting for the final document, allowing legal circulation during the processing of the file.
