Area code 773 covers the city of Chicago outside the central Loop area, which uses 312. The code serves most of Chicago's diverse neighborhoods from Rogers Park on the far north to Beverly on the far south, including the South Side communities, Wicker Park, and Hyde Park (home of the University of Chicago). The code was split from 312 in 1996.
Across Illinois, the 773 area code serves roughly 2 million residents in 4 communities — including Chicago, Wicker Park, Hyde Park, among others.

773 was first introduced in 1996 under the North American Numbering Plan. It remains an active geographic code today.
