Booking a slot for the practical driving test as a private candidate relies on a precise administrative chain: obtaining the NEPH, validating the file, and then accessing the booking schedule. Each link can block the next, and the timelines vary depending on the departments and the time of year. Understanding where the friction points are between Candilib, Candibot, and the RdvPermis system allows for anticipating blockages rather than suffering them.
Candilib, Candibot, and RdvPermis: what distinguishes them concretely
Private candidates often confuse these three names. They do not serve the same function and do not cover the same territories.

| Tool | Main function | Managed by | Current status |
|---|---|---|---|
| Candilib | Booking practical exam slots | Road safety (State) | Replaced by RdvPermis in most departments since May 2023 |
| Candibot | Automated bot for monitoring available slots | Third-party developers | Active, but depends on the availability of slots on the official platform |
| RdvPermis | National booking platform (successor to Candilib) | Road safety (State) | Deployed nationwide |
Candilib was the first government platform allowing private candidates to book their own exam dates. Candibot, on the other hand, is not an official service: it is a third-party tool that automatically scans for available slots and alerts the candidate as soon as a spot opens up.
Since the national deployment of RdvPermis, registration on Candilib and Candibot effectively redirects to the same government booking system, but the name Candilib remains entrenched in candidates’ searches.

NEPH and ANTS file: common blockages before booking
Before even accessing a booking schedule, the candidate must have a valid and active NEPH number. This number, contained in the AIPC (Certificate of Registration for the Driving License), is obtained through the ANTS portal, either via FranceConnect or by directly creating an account.
The first friction point is at the level of the supporting documents. The list varies depending on the candidate’s profile:
- Valid identity document and digital photo-signature (specific ANTS format, often rejected if framing standards are not met)
- Proof of residence less than six months old, or accommodation certificate accompanied by the host’s identity document
- ASSR2 or ASR for candidates born after 1987, JDC (Defense and Citizenship Day) certificate for French candidates over sixteen, or medical notice if a health issue is declared
An incomplete file or one with a non-compliant photo leads to a silent rejection: the status remains pending without clear notification. Regularly checking the status of the file on the ANTS portal helps avoid losing several weeks.
The case of former candidates: retrieving an existing NEPH
Candidates who have registered in the past (through a driving school or a previous attempt as a private candidate) often have a NEPH without knowing it. Creating a new file when a NEPH already exists causes a duplicate that blocks the booking. The procedure is to log in to the ANTS portal, under “driving license,” to find the old file and reactivate it.
When online booking finds no available slots
Obtaining the NEPH does not guarantee quick access to the exam. Booking the practical slot constitutes the second bottleneck, and this is where candidates’ frustration is most acute.
Slots are released in waves, often at the beginning of the week or on fixed dates according to the prefectures. A candidate checking the schedule mid-week may see no available spots, while slots were accessible just a few days earlier. This is precisely the problem that Candibot aims to solve by automating monitoring.
What Candibot can and cannot do
Candibot monitors the official schedule and sends an alert when a slot appears (usually a cancellation by another candidate). However, the tool does not create a slot: if no spots are released in your department, Candibot remains silent.
Another concrete limitation is reactivity. Between the alert and the candidate’s login, the slot may already have been taken by someone else. In high-demand departments, the window of availability for a canceled slot can sometimes be measured in minutes.
- Check the official schedule manually at least twice a day, in the early morning and late afternoon
- Activate Candibot notifications in parallel, without relying exclusively on them
- Broaden the geographical search area to neighboring departments, where the pressure on slots may be lower

File expiration and loss of slot: administrative pitfalls
An ANTS file has a validity period. If the candidate does not take the exam within the allotted time after obtaining the NEPH, the file may expire and require complete re-registration. This situation particularly affects candidates who have not found a slot in time.
Cancelling a reserved slot is possible, but under certain conditions. A late cancellation (too close to the exam date) can result in a penalty period before being able to book a new slot. The candidate then finds themselves at the back of the queue.
What to do when everything seems blocked
When the schedule remains empty for several weeks and the file approaches its deadline, two concrete options exist. The first is to directly contact the driving license office of the prefecture to report the urgency and ask if additional sessions are planned. The second is to temporarily enroll in an online driving school that has its own exam slots, bypassing the queue of private candidates.
The path of the private candidate remains free in terms of registration, but it requires constant administrative vigilance. An active NEPH, a complete file from the start, and a booking strategy combining manual checks and tools like Candibot significantly reduce the risk of ending up without an exam date.
