Willis Tower, the iconic 110-story skyscraper in Chicago's Loop, operates under dedicated ZIP code 60684. Designed by Skidmore, Owings & Merrill and completed in 1973 as the Sears Tower, the 1,451-foot building held the title of world's tallest for nearly 25 years. Today it remains the third-tallest building in the Western Hemisphere. The Willis Tower alias was added to postal records in December 2017, though postal records still show both the Sears Tower and Willis Tower names.
More than 1.7 million visitors annually come to the Skydeck, the highest observation deck in the United States. Following a $500 million redevelopment completed in recent years, the tower has been reimagined for modern office use while preserving its landmark status. With only 3 delivery codes on file, this ZIP handles building management correspondence rather than tenant mail. The designation predates 2004, and Chicago remains the valid mailing city.
