What is KTN/TSA Pre-Check and Redress Numbers
While these numbers are all entered in the same section of your profile, they serve entirely different purposes. Here is a quick breakdown to help you identify which number you have:
1. KTN (Known Traveler Number) / TSA PreCheck
What it is: A unique 9 or 10-character ID issued by the U.S. government (TSA or Department of Homeland Security) to approved travelers.
What it does: It grants you access to expedited security lanes at U.S. airports, allowing you to keep your shoes, belts, and light jackets on, and leave laptops in your bag.
Where to find it: If you applied directly for TSA Pre-Check, your KTN typically starts with
TT,TE, orAC. If you have Global Entry, your KTN is the 9-digit PASS ID located on the back of your physical Global Entry card.Note: This is entirely separate from airline frequent flyer or loyalty rewards numbers.
2. Redress Number
What it is: A unique 7-digit numeric code issued by the Department of Homeland Security (DHS) TRIP program.
What it does: This is not a rewards or expedited security program. It is exclusively for travelers who regularly face extra, mistaken screening delays at the airport; usually because their legal name matches someone on a government watch list. The Redress number solves this misidentification.
Where to find it: This will be explicitly labeled as a "Redress Control Number" on official correspondence from the DHS if you filed a case with them. If you have never had issues with mistaken identity at airport security, you likely do not have or need a Redress number.
Adding Your KTN/TSA PreCheck Number
You can add your KTN or TSA PreCheck number using one of these methods:
- Through Your Traveler Profile: The most permanent way to add your KTN/TSA PreCheck number is directly within your ITILITE traveler profile settings. Once you navigate to your profile, look for the membership or loyalty details section, where you can input and save your number. This ensures it's stored for all future bookings.


- On the Flight Confirmation Page: When you're in the process of booking a flight, the confirmation page provides an opportunity to add or edit your KTN/TSA PreCheck number before you finalize your booking.
Once your KTN/TSA PreCheck number is successfully saved in your profile, ITILITE will automatically populate it on the flight confirmation page for all your subsequent flight bookings. This means you won't have to manually enter it each time you travel, making your booking process even faster and more efficient.
