What is KTN and Redress Number
Whether you’re a frequent flyer or planning your next international trip, you’ve likely come across terms like Known Traveler Number (KTN) and Redress Number during flight bookings or airport check-ins. While U.S. government agencies issue both, they serve very different purposes, and understanding the difference can save you time, frustration, and even unwanted delays. In this guide, we break down everything you need to know about KTNs and Redress Numbers — who needs them, how to get them, and how they help make your journey smoother. What Is a Known Traveler Number (KTN)? A Known Traveler Number (KTN) is a unique identification number assigned to travelers who have been approved for TSA PreCheck® or other Trusted Traveler Programs like Global Entry, NEXUS, or SENTRI. Why It’s Useful: Your KTN allows you to access expedited security screening lanes at U.S. airports. With TSA PreCheck®, you can breeze through security without removing your shoes, belt, or jacket — and keep your laptop and liquids in your bag. It’s a game-changer for frequent travelers. Who Issues It: TSA for TSA PreCheck® CBP (U.S. Customs and Border Protection) for Global Entry, NEXUS, and SENTRIIn these programs, your KTN is often labeled as your PASSID. How to Use It: Simply enter your KTN when booking your flight — there’s usually a field labeled “Known Traveler Number” during the booking or check-in process. Make sure the name on your ticket matches exactly with the name in your Trusted Traveler account to avoid any issues. Where to Find It: On the back of your Global Entry, NEXUS, or SENTRI membership card In your Trusted Traveler Program account on ttp.dhs.gov Or use the official TSA KTN Lookup Tool Tip: Include your KTN in your frequent flyer profile with each airline so it’s automatically applied every time you book a flight. What Is a Redress Number? A Redress Number is a unique identifier assigned to travelers who have experienced repeated travel disruptions or delays due to being mistakenly flagged by airport security systems, often because their name is similar to someone on a federal watchlist. Why It’s Important: If you’ve ever faced: Frequent secondary screenings Unexplained delays during check-in Boarding denials or travel restrictions A Redress Number can help resolve these issues and clear your name in the system. Who Issues It: The Department of Homeland Security (DHS) via the Traveler Redress Inquiry Program (DHS TRIP). How to Get It: File a case on the DHS TRIP website Once your application is reviewed and approved, you’ll be issued a Redress Number How to Use It: Include it in your flight booking (under “Redress Number”) Provide it to airline staff if you’re facing check-in issues It helps airlines and TSA identify you as someone who has been cleared of previous misidentifications Note: A Redress Number does not grant access to expedited security screening — it is only used to resolve identity mismatches.
