Denver is a really good airport if you need to mail correspondence, both pre-security or while waiting for a plane.
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
All drop boxes are on the “main” level of each terminal, near the center cores, and they are on the side of the terminal that houses the lower-number gates. Look for signs that say “US Mail”; they are silver boxes mounted in the wall.
No more Post Office!
A USPS retail location was available in the main terminal, but it’s been since closed.
