TSA PreCheck vs Mobile Passport: Timing Is Everything
Most travelers think of these as interchangeable. In reality, TSA PreCheck is only for security screening on departure—never for immigration. Mobile Passport is only used during U.S. reentry—never for pre-flight security. Using both is possible, but the value depends on your typical journey and airport habits.
How to Optimize Your Journey Using Both Programs
Here’s how a trip looks if you want to use both TSA PreCheck and Mobile Passport.
Book Flights Linked to Your KTN
Attach your TSA PreCheck Known Traveler Number when booking for departure perks.
Airlines must receive your KTN in advance for your boarding pass to show PreCheck access.
Use TSA PreCheck at the Security Line
Follow PreCheck signs for expedited screening—no shoes or laptop removal.
PreCheck is processed before you reach the gate and only at participating domestic airports.
Download and Complete Mobile Passport on Arrival
Open the Mobile Passport app at the U.S. border and fill out your profile and declarations.
Mobile Passport is accepted at select airports and allows use of special lanes for U.S. citizens and Canadians.
Present Your Digital QR Code to CBP
Show your Mobile Passport QR and passport to the customs officer.
This happens after deplaning, separate from baggage or PreCheck lines.
