While you typically do not need to show ID simply to scan a standard theme park ticket at the turnstiles, French law technically requires all visitors to carry a valid national ID or passport at all times. For non-EU citizens, this means having your original passport on your person, as a driving license is often not considered sufficient proof of legal entry by French authorities. At Disneyland Paris specifically, ID is frequently requested for age verification (to prove a child is under 3 for free entry or under 12 for child pricing) and at City Hall when requesting birthday badges or assistance. Furthermore, if you have a "Disneyland Pass" (Annual Pass) or are using a "Priority Card" for disability access, you must present a valid government-issued photo ID every time you enter to verify that you are the registered pass holder. To avoid potential legal issues or being denied specific guest services, it is highly recommended to keep your passport or a very clear color photocopy in a secure, waterproof bag while exploring the resort.
