I entered my Known Traveler Number (KTN) in my reservation, but there's no TSA PreCheck® indicator on my boarding pass. What should I do?

First, check that your membership has not expired by looking up your account here.  

If still active, confirm with your airline that your Known Traveler Number, name, and date of birth are accurate and that your airline participates in TSA PreCheck®.  If you still do not have a TSA PreCheck indicator on your boarding pass, please call the TSA Contact Center at (866) 289-9673, submit an online form, or contact us at @AskTSA on Twitter and Facebook Messenger.  

If possible, please contact  TSA within 72 hours of experiencing problems with your TSA PreCheck benefits to allow TSA the ability to trouble shoot the issue.
