**ADA is an option for a licence held for less than one year**, although I couldn’t confirm an active branch in Caen.

ADA’s official FAQ says its *Ada Jeunes* offer allows rentals **from the day you receive your full driving licence**, provided you are at least 18. You must present the actual licence; a driving-test pass certificate is insufficient. [ADA’s young-driver policy](https://faq.ada.fr/hc/fr/articles/7306016296476-Comment-louer-une-voiture-en-%C3%A9tant-jeune-conducteur).

The local complication is that the former ADA branch on Rue d’Auge is listed as **probably permanently closed**. Treat older Caen listings cautiously. [Caen branch listing](https://www.pagesjaunes.fr/pros/50223335).

Your best next step is to contact ADA through its [website](https://www.ada.fr/) and ask which operating branch nearest Caen offers *Ada Jeunes*. Give them your age, licence-issuing country, and original issue date, and get confirmation before paying. You could write:

> Je souhaite louer une voiture avec mon premier permis, obtenu le [date] en [pays]. Acceptez-vous un permis de moins d’un an dans le cadre de l’offre Ada Jeunes ?

Be careful with other companies’ “young driver” offers: **Rent A Car’s “Jeune permis” option still requires at least one year**, so it doesn’t solve your situation. [Rent A Car’s conditions](https://www.rentacar.fr/nos-dossiers/43-location-jeune-conducteur).

Thus, there is a company advertising an exception, but I haven’t verified a qualifying pickup location in Caen itself.
