With new telephone numbers in southern Illinois in high demand, the Illinois Commerce Commission approved the implementation of the new 730 area code to overlay the existing 618 area code region. The current 618 area code serves all or part of 37 counties, including communities like Alton, Belleville, Cairo, Carbondale, Centralia, Collinsville, East St. Louis, Edwardsville, Effingham, Granite City and Marion, among many others.
Starting on July 7, customers in the 618 area code overlay region may be assigned a number in the new 730 area code when they request new service or an additional line. The 730 area code will co-exist everywhere in this region.
