Evanston, IL is currently using two area codes 224 and 847. Evanston, IL utilizes an area code overlay in which
area codes 224 and 847 serve the same geographic area. The area code overlay which is in use in Evanston, IL today was established in 2002 at which time area code 224 was created as an overlay of area code
847. Area code 847 was originally established in 1996. Ten digit dialing (area code + seven digit number) is necessary in Evanston because two different homes in the same geographic area can have the same
seven digit phone number but each would have a different area code.

Grove, Carpentersville, Des Plaines, Elgin, Elk Grove Village, Glenview, Gurnee, Highland Park, Hoffman Estates, Lake Forest, Lake in the Hills, Libertyville, Morton Grove, Mount Prospect, Mundelein, Niles,
