Denver is a really good airport if you need to mail correspondence, both pre-security or while waiting for a plane.
Official Information
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
User-Submitted Information
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.
