The Ochopee Post Office is the smallest operating post office in the United States. Measuring a mere 61 square feet, it is a tiny shed on U.S. Route 41 in Collier County near Ochopee, Florida. It is located about 3 miles (5 km) east of the intersection of US 41 and State Road 29. Its ZIP code is 34141 in Area Code 239, Exchange 695.

The building used to be a storage facility for irrigation pipes of an adjacent tomato farm. It was converted into a post office in 1953, after a fire destroyed Ochopee’s previous post office, located in the Gaunt Company Store. 

The post office is fully functional, serving a three-county area, including the surrounding populations of Miccosukee and Seminole Native Americans. Tour buses often stop at the site and the postal clerk is asked to cancel letters with Ochopee’s postmark.

The present structure has been in continuous use ever since – as both a post office and ticket station for Trailway’s bus lines – and still services residents in a three-county area, including deliveries to Seminole and Miccosukee Indians living in the region. Daily business often includes requests from tourists and stamp collectors the world over for the famed Ochopee postmark. The property was acquired by the Wooten Family in 1992.
