How will I know that I have TSA PreCheck™?

Participating airlines print a TSA PreCheck™ indicator directly on your boarding pass if you are eligible for TSA PreCheck™ on that flight. In addition to the indicator, TSA PreCheck™ eligibility is embedded in the barcode of the boarding pass. Once the boarding pass is scanned at the checkpoint, the TSA officer may refer you to the TSA PreCheck™ lane. If you do not have a valid boarding pass with TSA PreCheck™ embedded in the barcode, you cannot access the TSA PreCheck™ lane.
