1144 Fifteenth Street, Suite 2600, sits in downtown Denver, Colorado, a short trip from the rest of the metro area including Aurora, Lakewood, and the northern Denver suburbs. This address was used by U.S. Customs and Border Protection for a temporary, one-off Global Entry enrollment event rather than a permanent walk-in enrollment center, so confirm on the Trusted Traveler Programs site whether it still shows as a scheduling option before planning around it. Denver-area travelers who need an ongoing (not one-time) local option should also check the Denver International Airport enrollment center, which operates on a continuing basis.

Whether you're targeting this Denver address or another enrollment center entirely, cancellations open up constantly as other applicants reschedule. Rather than refreshing the Trusted Traveler Programs site by hand, savvy travelers set up Snapslot to send a real-time text the moment a matching slot appears, so they can grab it before anyone else does.
Knowing the Global Entry Application Process
- Submit Your Application: Create a Trusted Traveler Programs account and submit the Global Entry application with the fee.
- Await Conditional Approval: CBP reviews your background before clearing you to schedule an interview.
- Schedule Your Interview: Denver-area interview slots can be limited. If nothing convenient is open, Snapslot can alert you the moment a cancellation appears.
- Attend Your Interview: A CBP officer reviews your documents and travel history in person.
- Await Final Approval: Most applicants hear back shortly after the interview.
Preparing for your interview
Bring your valid passport book and a second form of ID. If the address on your driver's license is not current, bring separate proof of residency such as a bank statement, utility bill, or mortgage statement. U.S. lawful permanent residents should bring their permanent resident card. Be ready to speak plainly to every country you've visited in the last five years; the interview is largely an honesty check confirming your in-person answers line up with your application. Dress professionally, as you would for any appointment with a federal officer.
Getting to your appointment
The address sits in Denver's downtown business district, alongside other office towers, so treat it like any downtown appointment: confirm the exact suite and building entrance on Google Maps ahead of time, and budget extra time for downtown parking and traffic. Given the CBD location, rideshare or downtown parking garages are typically more predictable than trying to find street parking near your appointment time.
No available appointments?
If you're flying internationally into a participating airport, Enrollment on Arrival can let you complete your Global Entry interview right when you land instead of booking a separate appointment. Otherwise, check the Trusted Traveler Programs site directly for openings, or let Snapslot watch it for you.
Skip the manual refreshing: Snapslot texts you the moment a Denver-area cancellation opens up.
