A redress number is a unique seven-digit identifier issued by the Transportation Security Administrations (TSA) Secure Flight program to match travelers with the results of their redress case through the DHS TRIP program. It is a case number issued by the Department of Homeland Security (DHS) to individuals who were falsely identified as posing threats to transportation security or public safety when flying. The redress number is used by the TSAs Secure Flight program to simplify the watchlist matching process and can prevent future false matches of people who have been misidentified as matching a watchlist in the past.
Not everyone needs a redress number, but if youve frequently been stopped for additional security during travel or have been denied travel for security reasons, you may consider applying for one to avoid this in the future. To obtain a redress number, you need to apply for the Department of Homeland Securitys Traveler Redress Inquiry Program (TRIP) . The redress number is different from a Known Traveler Number (KTN), which identifies your membership in Trusted Traveler programs like TSA PreCheck and Global Entry.
