If you have NEXUS, you almost certainly do not need a NEXUS redress number, because no such thing is issued. Two different identifiers get confused here. NEXUS members receive a nine-digit CBP PASS ID, which goes in the Known Traveler Number field when booking a flight and unlocks TSA PreCheck. A redress number is a separate seven-digit number issued by the DHS Traveler Redress Inquiry Program (DHS TRIP) only to travelers who keep getting flagged or misidentified during screening. Most NEXUS members never need one.
The Number NEXUS Members Actually Use
When booking a flight, a NEXUS member enters their CBP PASS ID in the airline’s Known Traveler Number (KTN) field. The PASS ID is nine digits and typically starts with 10, 13, 14, 15, 16, 50, 70, 80, 95, 98, or 99.1TSA. What Is a Known Traveler Number You can find it on the back of your NEXUS card in the upper-left corner (the nine digits before “SC”), or by logging into the Trusted Traveler Programs site at ttp.cbp.dhs.gov.2U.S. Customs and Border Protection.

Carrying the physical NEXUS card is not enough. The PASS ID has to be in the reservation itself for the TSA PreCheck indicator to print on your boarding pass.3TSA. Can I Access TSA PreCheck by Showing My NEXUS Card Most airlines let you save the number in your frequent-flyer profile so it copies onto every booking automatically. If you add it after checking in, you’ll usually need to reprint the boarding pass for the indicator to show.4American Airlines. TSA PreCheck
U.S. citizens, U.S. lawful permanent residents, and Canadian citizens enrolled in NEXUS are eligible for TSA PreCheck when flying from participating U.S. airports.2U.S. Customs and Border Protection. NEXUS PASSID and Known Traveler Number
What a Redress Number Is For
A Redress Control Number is a seven-digit number issued by DHS TRIP. Its job is different from a KTN: it helps the Secure Flight screening system tell you apart from someone with a similar name or biographical profile who may appear on a watchlist.5DHS TRIP. DHS TRIP Frequently Asked Questions
You may want to apply for one if you have repeatedly experienced:
- Referrals to secondary screening at airports
- Denied or delayed boarding
- Denied or delayed entry at a U.S. port of entry or border crossing
- Inability to print a boarding pass6TSA. Travel Redress Program
The pattern that matters is persistent, unexplained trouble suggesting you’re being confused with someone flagged in a government database. Travelers whose problems come from a criminal record or from excessive intoxication are generally not eligible.7Chase. Redress Number vs Known Traveler Number
If a booking form has a redress number field and you don’t have a redress number, leave it blank.8DHS. Redress Control Numbers It is not a standard part of the travel process.
Can You Use Both Numbers Together
Yes. The KTN field and the redress number field are separate, and they do different things. The KTN field takes the nine-digit PASS ID from a trusted traveler program like NEXUS, Global Entry, SENTRI, or TSA PreCheck. The redress number field takes the seven-digit DHS TRIP number. DHS specifically warns travelers not to put one number in the other’s field.5DHS TRIP. DHS TRIP Frequently Asked Questions
If you happen to hold both, enter both on every reservation.9American Airlines. TSA PreCheck Information The KTN gets you expedited screening; the redress number helps prevent misidentification. They work independently.
The collection isn’t optional on the airline’s side. Under 49 CFR § 1560.101, covered aircraft operators must request your full name, sex, date of birth, and redress number, and transmit that data to TSA before departure as part of Secure Flight.10eCFR. 49 CFR Part 1560, Subpart B
How To Apply If You Do Need One
Applications go through the DHS TRIP portal at trip.dhs.gov. Each traveler files individually; family or group applications are not accepted. You’ll need to describe the travel difficulty, sign a Privacy Act statement, and upload a legible copy of the biographical page of an unexpired passport. If you don’t have a passport, at least one unexpired government-issued photo ID such as a driver’s license is required.5DHS TRIP. DHS TRIP Frequently Asked Questions
Once a complete application is in, the system assigns a Redress Control Number. Processing times vary; one source estimates up to 50 business days.7Chase. Redress Number vs Known Traveler Number If something is missing, the portal shows an “Info Needed” status, and you have 30 days to respond before the case closes automatically.5DHS TRIP. DHS TRIP Frequently Asked Questions
When the case closes, your Redress Control Number appears in your DHS TRIP profile and in the final determination letter, which downloads from the “My Cases” section. If you lose the number later, you can retrieve it by emailing TRIP@tsa.dhs.gov with your full name, date of birth, gender, and city and state of residence.8DHS. Redress Control Numbers
The number doesn’t expire. Use it on every future reservation. If your legal name changes or you get a new passport, contact DHS TRIP to update the existing record rather than filing again.5DHS TRIP. DHS TRIP Frequently Asked Questions
One caveat: DHS TRIP does not guarantee delay-free travel. The program states that additional screening may still occur for reasons outside the redress process.5DHS TRIP. DHS TRIP Frequently Asked Questions The DHS TRIP website has also carried a notice since February 17, 2026, that it is not being actively managed during a lapse in federal funding, so new inquiries and status checks may be disrupted while any lapse continues.11DHS.
