What steps should be taken after the purchase?
Once the used vehicle has been purchased, several essential steps must be taken to ensure legal operation. First of all, updating the registration document, now called the registration certificate, is essential. It’s important to remember that, since 2020, the law requires that a change of ownership be made within one month of purchase.
In addition to this update, there are a few situations that may require a change of license plates. Most recently purchased vehicles can, under certain conditions, retain their original registration number, especially if the vehicle is already registered in the new SIV (Vehicle Registration System) format. However, there are exceptions that require vigilance and attention to avoid any violations.
Here are the main steps to follow:
- Obtain the Provisional Registration Certificate (CPI): This temporary document is essential and must be downloaded from the ANTS (National Agency for Secure Titles) website.
- Request a registration card update: this can be done online. Various websites such as Service Public offer detailed information on the steps to follow.
- Order new license plates, if necessary. This is most often done by a professional.

Why might a license plate change be necessary?
For administrative and legal reasons, some license plate changes are sometimes essential. Two common scenarios specifically require a license plate update.
First, when there is a change of ownership of a vehicle registered in the FNI format (old registration system), it must be converted to the new SIV system. In other words, even if the vehicle keeps its license plate for life, a number change is inevitable in this case. A change of address may also require a license plate change. For owners whose vehicles are still registered in FNI format, updating their plates is also required to comply with the law.
The implications of this license plate swap are significant, as failure to comply with these requirements can result in fines and tickets. Motorists must therefore be vigilant and informed of their situation.

The deadlines for installing new license plates are clearly established. When you receive your new registration document, it is imperative to change your plates within a maximum of 48 hours. This short period begins as soon as you receive the Provisional Registration Certificate (CPI), provided after applying for the new registration document.
It is crucial to understand that this deadline is non-negotiable; failure to comply can result in significant fines. In 2025, a Class 4 traffic ticket can cost approximately €135, a fine that can be reduced to €90 if paid within 15 days of the offense.
For motorists who wish to avoid such inconvenience, it is advisable to follow a rigorous process:
Receive the CPI.
- Arrange for the production of new plates by a professional.
- Install the new plates on the vehicle within 48 hours. Action

Before purchasing, it is crucial to ensure that the existing plates are not damaged or illegible.

- Neglecting to read the information provided: The various documents, such as the CPI (Cultural Identification Card), must be carefully read and understood in order to comply with deadlines.
