If TSA discovers a fake ID in 2026, the consequences are severe and multifaceted. First, TSA officers are trained to detect fraudulent documents using advanced technology like Credential Authentication Technology (CAT-2), which scans for security features and cross-references government databases. If an ID is flagged as fake, the TSA will immediately notify local law enforcement. Depending on the state and the intent (e.g., an underage person using a fake ID to fly versus someone using a stolen identity), you can be arrested on the spot and charged with a felony or misdemeanor for possession of a forged instrument. Additionally, beginning February 1, 2026, travelers without a valid Real ID or passport must undergo an enhanced ConfirmID process, which costs $45 and involves a biometric scan and deep database check. However, if you are caught intentionally presenting a fake ID, the TSA may permanently revoke your TSA PreCheck or Global Entry status and place you on a "secondary screening" list for all future travel. It is a federal offense to provide false information to a federal officer, which can lead to thousands of dollars in fines.
