Generally, Disney does not check IDs for children for the purpose of age verification at the gate. Disney World requires a child's ticket for those aged 3 to 9, while those under 3 are admitted for free. Cast members at the entrance typically take a parent's word for it, though they may occasionally ask a child directly how old they are. Because the policy is based on "let your conscience be your guide," it is very rare for a guest to be asked for a birth certificate or passport. However, if your child is tall for their age and appears significantly older than 2, some cautious parents bring a digital photo of a birth certificate or a passport on their phone just in case there is a dispute. For children aged 10 and up, who are charged adult prices, no ID is required either, as the ticket itself is the verification. The only time ID is strictly required for "minors" is if they are utilizing a specific Florida Resident discount or if they are teenagers traveling without an adult who need to prove their identity for a hotel check-in.
