I entered my 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 KTN, 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 the TSA Contact Center three days before or after travel to improve TSA's ability to trouble shoot the issue.
