A cyberattack against ANTS in mid-April 2026 paralyzed France Titres for several weeks. Registration certificates, car insurance, technical inspections: the dematerialization of these processes relies on a technical chain where each link can fail. Understanding the points of fragility and operational alternatives ensures that one never gets stuck.
ANTS Cyberattack and Registration Certificate: Anticipating Online Process Failures
The prolonged outage of France Titres revealed a critical dependency. When the centralized portal goes down, requests for registration certificates, transfer declarations, and changes of ownership are suspended. Authorized professionals (approved SIV garages, private platforms with API access) sometimes retain residual access, but their own systems depend on the same ANTS back-end.

Simplimmat remains functional even during partial maintenance of the ANTS website, because the mobile application uses a distinct authentication channel (FranceConnect on smartphone). In the event of another major outage, three backup options exist.
- The provisional registration certificate (CPI) generated by Simplimmat or an authorized professional, which allows circulation for one month without waiting for the final registration certificate.
- Turning to an authorized SIV professional, capable of processing certain operations via their own portal as long as the API remains partially accessible.
- The systematic retention of digital copies of all documents (transfer, technical inspection, insurance certificate) to resume the process as soon as service is restored, without reconstructing the file.
We recommend never planning a vehicle sale or purchase the day before a deadline (expiration of technical inspection, expiration of a CPI) without checking the status of the ANTS service on the same day.

A comprehensive overview of these backup mechanisms is detailed in the autofantom fr solutions on Blog Automobile, which also covers insurance and technical inspection aspects.
Technical Inspection and Registration Certificate: The Administrative Sequence Many Overlook
Without a valid technical inspection, any operation on a used vehicle is blocked. The transfer declaration via Simplimmat or the ANTS site requires an inspection dated less than six months ago. An expired inspection by just one day is enough to render the request for a change of ownership inadmissible.
The validity of the technical inspection conditions the entire documentary chain, not just resale. A change of address on the registration certificate, for example, does not require an inspection. However, a duplicate for loss or theft may be refused if the system detects an expired inspection associated with the vehicle.
Check Document Consistency Before Any Process
Before initiating an online procedure, we observe that the majority of rejections stem from inconsistencies between the registration certificate and the technical inspection report: incorrectly entered registration number, inconsistent mileage, or different vehicle type (VP instead of CTTE, for example). A cross-check of the two documents takes a few minutes and avoids a blockage of several days.
Online Car Insurance: What the Contract Must Cover to Validate Your Processes
The insurance certificate is the third documentary pillar. It is required for circulation, for the technical inspection, and, in some cases, to finalize a registration on the ANTS portal. The car insurance contract taken out online generates an immediate provisional certificate, but this provisional certificate is not always accepted by technical inspection centers.
Some centers require the definitive green card or, since the gradual dematerialization of the insurance certificate, verification via the Fichier des Véhicules Assurés (FVA). The registration delay with the FVA after online subscription varies by insurer. A driver who subscribes to a contract in the morning and presents for inspection in the afternoon may be denied access.
Coverage and Certificate: Two Distinct Levels
The contract can include all desired coverages (liability, theft, glass breakage, assistance), but only the mention of mandatory liability appears on the certificate sent to the SIV. Additional coverages have no impact on the administrative validity of the vehicle. A third-party contract is sufficient to register, sell, or have a vehicle inspected.
We recommend checking effective registration with the FVA before making an appointment for a technical inspection or initiating a registration process. Most online insurers now display the FVA status in the client area.
Simplimmat and Authorized Platforms: Choosing the Right Channel According to the Situation
Simplimmat covers a specific scope: the transfer between individuals of vehicles registered in the SIV format (AA-123-AA) and certain types (VP, CTTE, MTL, MTT1, MTT2, among others). Vehicles still in the FNI format (old departmental number) or transactions involving a professional are not covered by the application.
For these cases, the ANTS portal or an authorized professional remains the only channel. The distinction is technical but has direct consequences: a buyer attempting to use Simplimmat for an FNI vehicle will waste time before being redirected.
- Simplimmat: transfer between individuals, SIV vehicle, provisional registration certificate issued immediately.
- ANTS Portal (France Titres): all procedures (change of address, duplicate, new registration, FNI vehicle), variable processing time.
- Authorized Professional: useful in case of ANTS outage, for complex files (imported vehicle, inheritance) or when the applicant does not have FranceConnect.
The definitive registration certificate arrives by mail within one to two weeks under normal circumstances. During peak periods or after a technical incident like the 2026 cyberattack, this delay can double. Retaining the CPI and regularly checking the online file status remains the only safeguard.
The reflex to adopt before any online procedure, whether it concerns insurance, registration certificate, or technical inspection: physically gather the three documents (insurance certificate, registration certificate, technical inspection report), check their mutual consistency, and only then open the portal or application. This preliminary step eliminates the vast majority of file rejections.
