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.
