All ticketed United Airlines passengers flying in and out of Denver International can now enroll in TSA PreCheck with no need for an appointment.

This TSA PreCheck enrollment option is available to all United passengers who are coming into, connecting through and leaving Denver.

The TSA PreCheck enrollment last for five years and currently costs USD 78.

How to enrol at Denver

Passengers can use the enrollment centre in Concourse B, between Gates B18 and B20.

Enrollment is available Monday through Friday, from 8 a.m. until 12 p.m. and 1 p.m. until 5 p.m. local time.

Passengers need to show a government-issued photo ID and proof of citizenship (e.g., passport, birth certificate) or lawful permanent residency.

What is TSA PreCheck?

TSA PreCheck is a program where a passenger gives personal details before travel and, if approved, they get a Known Traveler Number (KTN).

That KTN means they can use dedicated security lines, keep their shoes on and leave their 3-1-1 (100ml bottles in 1 bag per person) liquids and laptops in their bags at hundreds of U.S. airports.

Passengers add their Known Traveler Number to their flight booking and receive a “TSA PreCheck” designation on their boarding pass. That allows them to use the dedicated security lines.


The TSA PreCheck system at Denver is operated by French company IDEMIA.

IDEMIA has been providing enrollment services to the TSA PreCheck pre-screening program since 2013.

The TSA has been using IDEMIA’s Credential Authentication Technology (CAT) at airport security checkpoints in 120+ airports around the United States since 2019.
