Redress Number vs Known Traveler Number: Which Box Is Yours?
The short answer on redress number vs known traveler: a Known Traveler Number (KTN) puts the TSA PreCheck indicator on your boarding pass, and a redress number is a 7-digit DHS TRIP case number for travelers who keep getting misidentified or sent to extra screening. They go in separate boxes on the booking form, and neither can stand in for the other.
If you are waiting on Global Entry, NEXUS or SENTRI, your KTN is the 9-digit CBP PASSID on your card. A redress number does nothing to speed that up. The rest of this page shows what each number is, then walks through a dated timeline for when your PASSID can realistically exist.
Redress number vs known traveler: which box do you fill in?
Most travelers have neither number, and a blank field is fine. Fill in a box only if you have that number.
| Known Traveler Number (KTN) | Redress number | |
|---|---|---|
| What it does | Prints the PreCheck indicator on your boarding pass | Links your booking to your DHS TRIP case so you stop being mistaken for someone else |
| Length | 9 digits for Global Entry, NEXUS and SENTRI (the CBP PASSID); 9 or 10 characters, letters allowed, for TSA PreCheck Application Program members | 7 digits |
| What it looks like | PASSID usually starts with 10, 13, 14, 15, 16, 50, 70, 80, 95, 98 or 99; PreCheck Application Program numbers start with TT, TE or AC | Digits only |
| Cost | Global Entry, NEXUS or SENTRI: $120 for 5 years. TSA PreCheck: $78 to $85 for 5 years, depending on the enrollment provider | Free |
| How you get it | Apply, get conditional approval, then complete an in-person interview | Submit the DHS TRIP Traveler Inquiry Form online |
| When you can use it | After you have the card or PASSID | After DHS finishes your inquiry and sends a final determination letter |
On a Global Entry, NEXUS or SENTRI card, the PASSID is printed in the upper-left of the back. The card itself does not get you into PreCheck lanes. You have to type the PASSID into the KTN field so the PreCheck indicator prints on your boarding pass. If you entered it correctly, you will see the PreCheck logo on the pass.

Who actually needs a redress number
The redress route exists for people who have been denied or delayed boarding, denied or delayed entry or exit at a port of entry, or repeatedly sent to secondary screening. Signs include:
- You cannot check in online.
- "SSSS" shows up on your boarding passes often.
- Someone tells you your name matches a watch list.
You apply through DHS TRIP, and a redress number is assigned the moment you submit the form. You can only use it on bookings once the inquiry is complete and you have the final determination letter. Third-party guides disagree on how long that takes: one says up to two months, another says usually a few weeks. Plan on weeks, and do not count on a date. Travelers with security issues tied to a criminal record or excessive intoxication may not be eligible.
You do not need to be in Global Entry or any trusted traveler program to apply for redress. A redress number is never printed on a Global Entry card. If you have one, you can add it to the "Redress Number" field in your Trusted Traveler Programs profile, and it can flow through to bookings along with your KTN.
Does a redress number speed up Global Entry, NEXUS or SENTRI?
No. They are separate systems. A redress number does nothing for PreCheck and nothing for your interview wait. Applying for one will not move you up any line.
TSA PreCheck members also cannot upgrade to Global Entry. Global Entry is a brand-new application with its own $120 fee, review and interview.
Worked example: from application to a PASSID in the KTN box
The numbers below are made up so the arithmetic is easy to follow. Swap in the dates from the live pages.
- Day 0: you apply and pay the $120 CBP fee (the fee since October 1, 2024; each membership lasts 5 years).
- About day 14: CBP says 80% of applications get a decision within about 2 weeks. Some take 12 months or longer. Conditional approval is what lets you schedule an interview.
- Interview date: this is the long wait. Open /global-entry-appointment-availability, find your center, and read its next bookable date. For NEXUS or SENTRI, use /nexus-wait-times or /sentri-wait-times.
- After the interview: the card, with the PASSID on the back, follows. That gap is covered in our turnaround-time guide.
Suppose you are approved on day 14 and your center's next bookable date is 95 days away. The interview lands around day 109, and the earliest realistic day for a PASSID is on or after that. Until then, the KTN box stays blank.

How much does the center you pick move that date?
Take three centers in the same region. These example gaps are invented to show the arithmetic, not current data:
| Center | Next bookable date (example) | Interview day if approved on day 14 |
|---|---|---|
| Center A | 20 days out | Day 34 |
| Center B | 95 days out | Day 109 |
| Center C | 160 days out | Day 174 |
In this example, the same traveler waits 140 days longer at Center C than at Center A. Check two or three centers on the availability page. The site also has live wait-time pages for Global Entry centers, linked from Global Entry wait times. A farther center with an earlier date can get you a PASSID months sooner, if the trip is workable.

One caution: the availability page shows each center's next bookable date, not whether a slot is open right now. Cancellations never show up on a page, so treat the date as an estimate for planning.
Can you have both a KTN and a redress number?
Yes, you can have both, and they go in separate fields on a booking form. If you have a redress number, add it to the Redress Number field in your Trusted Traveler Programs profile so it can flow through to bookings along with your KTN.
Where to enter each number
Enter them on the airline's passenger-details page, or save them once in your frequent-flyer profile so they fill in automatically. If you forget, an airport agent can add either number at check-in.
Getting an earlier interview slot
If your center's next bookable date is months out, you can keep refreshing the availability page by hand. GlobalEntryTexts is built to do that watching for you: monitoring runs 24/7, and it texts you when a Global Entry, NEXUS or SENTRI interview appointment opens at the enrollment centers you choose. You can watch up to 3 centers for the same price, texts are unlimited during the 30 days, and no account or login is needed to get alerts.
The limits are plain. It costs $25, paid once, for 30 days of monitoring; it is not a subscription. It is a website with no app to install, and alerts are SMS texts only. You book the appointment yourself on ttp.dhs.gov, because it never books for you. A text is not a booking, and nobody can promise you an appointment.

Yes. They go in separate fields. You can also add your redress number to the Redress Number field in your Trusted Traveler Programs profile so it can flow through to bookings with your KTN.
