I think my TSA PreCheck membership was suspended or revoked, but I'm not sure why, what do I do?

First, check that your membership has not expired by looking up your KTN (Known Traveler Number) here. You can also confirm your airline participates in the TSA PreCheck® program, by clicking here.

If your KTN is still active, confirm with your airline that your KTN, name, and date of birth are accurate.

If you still do not have a TSA PreCheck® indicator, or if you have questions concerning your TSA PreCheck® status, call the TSA Contact Center at (866) 289-9673, submit an online form, or contact us at @AskTSA on Twitter and Facebook Messenger.  If you received a notice of violation, please contact your case agent.
