The Old Chicago Main Post Office is a nine-story Art Deco and Neoclassical office building in downtown Chicago, designed by the prominent firm Graham, Anderson, Probst & White and completed in 1921. Its structure was greatly expanded in 1932 to accommodate the city's surging postal volume, driven in part by mail-order giants Montgomery Ward and Sears. After the postal service relocated to a modern processing center in 1997, the building was sold for redevelopment in 2009 and underwent extensive restoration, subsequently housing corporate offices for companies including Ferrara Candy Company, PepsiCo, Cisco Systems, Uber, and others. It is listed on the National Register of Historic Places.
