TSA PreCheck Acceptable Identification refers to the valid forms of ID required to use the TSA PreCheck expedited security screening lanes at airports. To enjoy the benefits of TSA PreCheck, travelers must present acceptable identification, including a valid U.S. passport, state-issued driver’s license, state-issued ID card, Permanent Resident Card (Green Card), or a military ID. Canadian and Mexican NEXUS cardholders also qualify. It’s crucial that these IDs are current and match the information in your TSA PreCheck account to avoid delays and ensure a smooth airport experience. Always verify and update your identification before traveling.
