224 Area Code in Illinois, United States

Description

Area code 224 is an overlay for area code 847, covering the northern suburbs of Chicago, including cities such as Evanston, Waukegan, Des Plaines, and Arlington Heights. It was introduced in 2002 to provide additional numbering capacity in this densely populated and economically active region. The 224/847 area includes a diverse mix of residential communities, corporate campuses, and retail hubs. Ten-digit dialing is required throughout the region. While 847 carries more historical recognition, 224 is commonly seen on new phone numbers, especially mobile and business lines. Together, they represent one of the most vibrant suburban regions in the state.
