How will I know that I can access TSA PreCheck® screening lanes?

Participating airlines display a TSA PreCheck® indicator directly on your boarding pass if you are eligible for TSA PreCheck based on your provided Known Traveler Number (KTN). Please ensure you add your KTN to your airline reservation while booking the reservation. If you do not have a valid boarding pass with a TSA PreCheck indicator on it, you cannot access the TSA PreCheck lane. If you believe you should have the TSA PreCheck indicator on your boarding pass but did not receive it, we're here to assist you.  You can reach out to us through X (Twitter @AskTSA), Facebook Messenger (http://www.fb.com/AskTSA), Apple Business Chat or by texting "Travel" to AskTSA (275-872). You can also contact the TSA Contact Center at (866) 289-9673(link is a phone number) or fill out an online form.
