Candilib, RDV Permis, Candibot: behind these names are tools with very different functions, which do not offer the same results depending on the candidate’s profile. Comparing their mechanisms allows for better arbitration between classic registration and free application, and especially to reduce the time between the end of training and the practical exam.
Candilib, RDV Permis, and Candibot: what each tool actually does
The confusion between these three names often arises. Candilib is the historical government platform for booking exam slots for free candidates. RDV Permis is the service that has gradually replaced or supplemented it depending on the departments, still managed by the Road Safety authority. Candibot, on the other hand, is not an official service: it is an automated robot (bot) that monitors available slots on the platform and alerts the candidate as soon as a spot becomes available.
| Tool | Nature | Access | Main function |
|---|---|---|---|
| Candilib | Official platform (State) | Free candidates with validated NEPH | Direct booking of an exam slot |
| RDV Permis | Official platform (State) | Free candidates and driving schools depending on the department | Slot booking, extension of Candilib |
| Candibot | Unofficial third-party service | Any candidate registered on Candilib/RDV Permis | Automatic detection of released slots |
The table highlights a point often overlooked: Candibot does not replace registration on Candilib. It complements it. Without an active NEPH number and a validated account on the official platform, the bot is useless.
To learn everything about Candilib and Candibot registration, the complete process deserves to be detailed step by step, as it is the administrative phase that blocks most free candidates well before the issue of the slot.

ANTS registration and NEPH acquisition delay: the real bottleneck
Even before thinking about booking an exam date, the free candidate must obtain their NEPH number (Harmonized Prefectural Registration Number) via the ANTS website. This process, entirely digital, constitutes the first filter.
- Create an account on the ANTS website and fill out the driving license application form (category B)
- Provide a valid ID, a compliant digital photo (e-photo format or approved photo booth), proof of residence, and for those under 25, the certificate of participation in the JDC
- Wait for the validation of the file, the time frame of which varies greatly depending on the departments, from a few days to several weeks
The NEPH remains valid for six years from its issuance. A candidate who exceeds this timeframe without taking the exam will have to restart the procedure from the beginning.
Once the NEPH is obtained, the candidate must also have a valid highway code. The result of the general theoretical test (ETG) expires after five years or after five attempts at the practical test, whichever comes first.
Candilib slots saturated: what Candibot changes (and does not change)
The main complaint against Candilib concerns the availability of slots. In the most densely populated departments (Île-de-France, Rhône, Bouches-du-Rhône), spots disappear within seconds after being posted online. This is precisely the problem that gave rise to Candibot and other similar alert services.
How Candibot works
Candibot scans the slots at regular intervals and sends a notification (SMS, email, or via an app) as soon as a cancellation frees up a spot. The candidate must then manually log in to Candilib to confirm the booking. The bot does not reserve on behalf of the candidate.
However, the real advantage of Candibot is limited to last-minute cancellations. When the slots are initially posted by the prefecture, all candidates are competing at the same time, bot or not. The tool becomes particularly useful in the days leading up to an exam when candidates free up their spots.
Limitations to know before subscribing
Some services like Candibot are free, while others charge a monthly subscription. None guarantee the acquisition of a slot. In departments where the number of free candidates remains low, the official platform is sufficient without resorting to a bot.

Driving hours and taking the exam as a free candidate: the gap between legal minimum and reality
The legal minimum for B license training is set at 20 hours of driving in a manual transmission (13 hours in an automatic), according to the decree of December 22, 2009, still in effect. This threshold is rarely sufficient for a candidate training without a traditional driving school.
The national average observed far exceeds this floor. Free candidates, who organize their own lessons with a companion or an independent instructor, must anticipate a higher volume of hours, especially in urban areas where traffic conditions complicate learning.
A regulatory point deserves attention for candidates retaking the license after cancellation or invalidation: the new title issued adopts the credit card format, valid for 15 years. All old cardboard licenses must be replaced before January 19, 2033, which involves a process on the ANTS or at a Maison France Services.
Access to Candilib or RDV Permis does not exempt any of these obligations. The platform verifies that the candidate has a valid NEPH and a current code before opening the booking. The obtained slot remains cancellable without penalty up to a few days before the date, according to the conditions displayed on the platform at the time of booking.
Whether the candidate goes through Candilib alone or with the help of a bot, the determining factor remains the preparation beforehand: NEPH obtained early, code validated, realistic volume of driving hours. The exam slot is just the last piece of an administrative journey that begins well before the date displayed on the summons.
