Yes, Disneyland Resort (both Disneyland Park and Disney California Adventure) maintains an extremely strict ID policy for the purchase of alcoholic beverages. Every guest, regardless of their apparent age, is required to present a valid form of identification if they wish to buy alcohol. For United States residents, acceptable IDs include a valid original State Driver's License, a Government-issued ID card with a photo and birth date, or a valid U.S. Passport. For international guests, the rules are even tighter: an original valid Passport is the only accepted form of ID; foreign driver's licenses or ID cards are not accepted on their own. Temporary licenses and paper copies of IDs are also strictly prohibited. Disney bartenders and servers are trained to be uncompromising with these rules, and they will refuse service to anyone who cannot produce the required physical documentation, even if they are clearly over the age of 21.
