Redress Number vs. Known Traveler Number: Understanding the Difference
Redress numbers are issued by the Department of Homeland Security Traveler Redress Inquiry Program. A Known Traveler Number (KTN) is for TSA PreCheck®.
At-A-Glance
A redress number is issued by the Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP) and is designed to help resolve travel issues that arise from mistaken identity or security concerns.1
A Known Traveler Number, or KTN, is issued to those who are approved for TSA PreCheck®, a program that allows travelers to access expedited security lines.2
A redress number and a Known Traveler Number can both assist with airport screening and security, but they are very different from each other.
What Is a Redress Number?
When passengers are screened by the Transportation Security Administration’s (TSA) Secure Flight program, there’s a chance that someone could be misidentified as high risk. A Redress Control Number, also known as a redress number is something that may be given to people who are mistakenly identified as threats to help them avoid similar security issues in the future.
The redress number is a seven-digit code that is issued by the Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP) and is used by the Transportation Security Administration’s (TSA) Secure Flight program to match a traveler with the results of their redress case.3
Why and When Do You Need a Redress Number?
The primary purpose of a Redress Number is to resolve travel-related problems that might arise due to mistaken identity or other security concerns. If you consistently face issues such as being misidentified on the No-Fly List or experiencing delays during security screenings, obtaining a Redress Number may help.
The Department of Homeland Security’s website states that DHS TRIP can assist in resolving travel-related issues, such as:
- You were unable to print a boarding pass from an airline ticketing kiosk or from the Internet;
- You were delayed or denied boarding an aircraft;
- The airline ticket agent informed you that the Federal Government was not authorizing you to travel;
- You are repeatedly referred for secondary screening when clearing U.S. Customs or were denied entry into the United States;
- You were told by CBP at a U.S. port of entry that your fingerprints need to be corrected;
- You wish to amend a traveler record because of an overstay as a result of not submitting the required I-94 when exiting the United States;
- You believe you were incorrectly denied ESTA authorization; or
- You believe your personal information was inappropriately exposed or shared by a government agent.

What Is a Known Traveler Number?
A Known Traveler Number, on the other hand, is a unique identification number assigned to those approved to participate in expedited security screening programs, such as TSA PreCheck®. TSA PreCheck allows eligible travelers to experience faster and more convenient security screening at participating airports.
What Are the Benefits of a Known Traveler Number?
Known Traveler Numbers have an array of benefits that may include:
- Expedited Security Screening: You may be able to enjoy shorter lines and faster security checks at participating airports, saving valuable time before your flight.
- Keep Shoes and Belts On: TSA PreCheck may allow you to keep your shoes and belts on during security screening, eliminating the need for time-consuming removal and reapplication.
- Leave Laptops and Liquids in Carry-On: Approved travelers can leave laptops and compliant liquids in their carry-on bags, streamlining the security process and reducing the hassle of unpacking and repacking.
- Efficient Screening Process: With a Known Traveler Number, you can experience a more efficient and less invasive screening process, contributing to an overall smoother travel experience.
How to Apply for a Known Traveler Number
To apply for a Known Traveler Number, visit the official TSA website. Navigate to the TSA PreCheck section and complete the online application form, providing accurate personal details, including your full name, date of birth, address, and citizenship information. Have a valid form of identification, such as a passport or driver’s license, ready for submission.
Following the online application, schedule an in-person appointment at one of the enrollment centers for a short interview and fingerprinting. Ensure you bring all necessary documents to the appointment, including proof of identity and citizenship.
Upon completing the application process and a satisfactory background check, you will be issued a unique Known Traveler Number. Use this alphanumeric code when booking flights to enjoy expedited security screening benefits through TSA PreCheck, making your travel experience more efficient.
Differences Between a Redress Number and a Known Traveler Number?
While both the Redress Number and Known Traveler Number aim to address travel-related issues, they are both very different and serve different purposes.
The Redress Number is designed to assist individuals facing consistent problems during security screenings, providing a means to resolve identity-related issues. On the other hand, the Known Traveler Number is linked to the TSA PreCheck program, offering a faster and more convenient security screening process for low-risk travelers.
The Takeaway
Whether you need a Redress Number to resolve previous travel issues or are considering a Known Traveler Number for a smoother airport experience, understanding the purpose and benefits of each is essential. By familiarizing yourself with these identification systems, you can make informed decisions that enhance the efficiency and comfort of your future travels.
