If you have TSA PreCheck, you don't have to take off your shoes or coat when you go through the security line.

Not every airline offers the service, so check your boarding pass beforehand.

There are two 9 digits numbers on the back of my Global Entry card, which is the correct number? The one under the PASSID word or the one to the right?

Your PASSID on your Global Entry card is the one you'll use as a KTN to gain access to TSA PreCheck lanes.

Question

I have renewed my TSA PreCheck and paid the $70. Is that all I need now? I have a paper that shows good thru 03/02/2027.

Staff Answer

In that case, you should be good to go! As long as you renewed before your previous membership expired (or within one year of expiration), you'll still have the same KTN. If you renewed before it expired, the renewal membership kicks in immediately after the old one expires.

Question

I have TSA PreCheck but keep not getting TSA PreCheck lane access on my flights. Why?

wikiHow Staff Editor
Staff Answer

wikiHow Staff Editor

Staff Answer

You have to provide your KTN to the airline when you book your flight. Then, you'll have a TSA PreCheck indicator on your boarding pass that allows you access to the TSA PreCheck lanes. Without that indicator on your boarding pass, TSA won't let you use the PreCheck lanes—even if you have an active membership.

Staff Answer

TSA sends notices periodically when it's about to expire. You can also find out the expiration date by entering your information on the TSA Enrollment website. Just look for the link for existing TSA PreCheck members and enter your KTN and any other information when prompted.
