Yes, you should always carry a government-issued photo ID when visiting Universal Studios Hollywood in 2026, as it is required for several key stages of entry and experience. While a child does not typically need ID for entry, adults must present ID to pick up "Will Call" tickets or to activate multi-day passes and Annual Passes. Universal uses a biometric (fingerprint) scan or facial recognition system for pass holders to prevent ticket fraud, but this is always validated against your physical ID during the initial registration. Furthermore, a valid ID is mandatory for the purchase of any alcoholic beverages within the park (California law is strictly "ID everyone") and for the use of "Express Passes" if a staff member requests verification. If you are a resident of California or a neighboring state using a regional discount, you must show proof of residency via your driver's license at the turnstiles. The "gold standard" is to keep your ID in a secure lanyard or a zipped pocket, as it is also necessary if you need to access "Lost and Found" or resolve any technical issues with your digital tickets in the Universal Studios Hollywood app.
