Denver is a really good airport if you need to mail correspondence, both pre-security or while waiting for a plane.
Pre-security Post Office!
A USPS retail location is available in the main terminal (Jeppessen Terminal), 6th level, on the west side of the airport. Outgoing mail can be dropped here 24 hours a day, 7 days a week. Check the airport Web site for more details regarding operating hours.
Post-security Drop Boxes
Look for drop boxes in the following locations:
- Terminal A: in the center core, NW corner
- Terminal B: in the center core around the food court
- Terminal C: on the mezzanine level
