This post office has no drop box anywhere outside. It has a small parking lot and even at night the parking lot was full. That made it hard to get in and out of the parking lot looking for the drop box.

I'm new to Rockford and this was the first time going to a post office in the area which is located in a lovely old civic building with an ADA compliant ramp for easy access for rollators/wheelchairs and Ms. Theresa provided me with absolutely WONDERFUL customer service!
