Any change of residence requires an update of the registration certificate within one month. This legal obligation, reinforced by the 3DS law which confirmed the definitive removal of prefecture counters, mandates an online procedure. Norauto, as a service provider authorized by the State, offers to carry out this formalities through its centers or its digital service, in addition to the official ANTS portal.
Free service on ANTS and fees with an authorized intermediary: what the regulations provide
The address change made directly on the site immatriculation.ants.gouv.fr is free for the first three changes. For the fourth consecutive change, a fee of 2.76 euros applies. Holders of an old registration plate (format 123 XX 50) also pay this fee from the first change.

Using an authorized provider like Norauto incurs additional service fees. These fees cover the handling of the file, verification of documents, and transmission to ANTS. Turning to an online address change for the registration certificate at Norauto is particularly justified when the procedure on the official portal poses technical difficulties or when the file has specific characteristics.
The authorities warn against unofficial sites that charge for this procedure at sometimes excessive rates. Checking the authorization of the provider before submitting documents remains a basic precaution.

Address change procedure for the registration certificate at Norauto: the concrete process
Norauto is authorized by the National Agency for Secure Titles (ANTS) to handle registration requests, including address changes. The procedure follows the same pattern regardless of the plate format.
Preparation of the file and supporting documents
Before starting, several documents must be gathered. Their absence systematically blocks the processing of the file.
- The original registration certificate (carte grise), with the detachable coupon if the document has one
- A proof of residence less than six months old (utility bill, tax notice, rent receipt)
- A valid identity document
- For new registrations: access to FranceConnect or the confidential code on the registration certificate
In case of loss of the certificate during the move, the procedure changes: a duplicate must be requested, which incurs additional fees and extends the processing time.
Transmission and obtaining the provisional certificate
Once the complete file is submitted at a Norauto center or via their online service, a provisional registration certificate (CPI) is issued. This document allows legal circulation while waiting for the final certificate to arrive by mail.
The CPI carries the new address and is valid in case of a road check. The final certificate usually arrives in the form of a sticker to be affixed to the registration certificate, unless the maximum number of address changes on the document has been reached, in which case a new registration certificate is issued.
Legal deadline and risk of fine in case of delay
The Highway Code sets the declaration deadline at one month after the change of residence. After this period, the vehicle owner is subject to a fine of 135 euros in case of a check.
This deadline runs from the effective date of moving to the new address, not from the signing of the lease or the real estate sale deed. This distinction is important for individuals who temporarily maintain two addresses.
The procedure through an authorized provider does not change this deadline: it is the date of submission of the complete file that counts, not the date of receipt of the final certificate. Submitting the file on time, even if processing takes a few weeks, is sufficient to be compliant.

Specific cases that complicate the address change for the registration certificate
Some situations fall outside the standard framework and deserve specific attention.
Vehicles in joint ownership (registration certificate in two names) require the agreement and supporting documents from both owners. If the co-owners no longer reside at the same address after the move, the situation may require a more complex modification than a simple address change.
Old registration plates (departmental format) automatically trigger the assignment of a new registration in the SIV format when changing the address. The vehicle then receives new plates, which adds a cost and an additional step.
Company vehicles or long-term rentals follow a different process: it is the holder listed on the registration certificate (often the leasing company) who must carry out the procedure, not the vehicle user.
Updating the address on the registration certificate remains a quick formality in most cases. The main point of vigilance remains the respect of the one-month deadline, whether the procedure is done directly through ANTS or through a Norauto center.
