Post Office 51401 (Carroll, Iowa)

The 21,000-square-feet Carroll Post Office opened its doors with little fanfare on Monday, July 13, 1970. Built at an estimated cost of $239,000, the air-conditioned facility offered four times the space as the previous building including rooms for record storage, mechanical equipment, mail bags and postal equipment. Customers benefited from the location move with a larger lobby, more post office boxes, and standalone mailboxes in the parking lot to allow letters to be deposited without leaving the car. The previous post office served the Carroll community for 46 years.
