Area code 618
From Wikipedia, the free encyclopedia
Area code 618 is the telephone area code serving the southern part of Illinois. It covers Belleville, Carbondale, Alton, Centralia, Mount Vernon and Southern Illinois. From time to time proposals have been made for another area code in Southern Illinois. Some of these proposals involve overlays and others involve splitting the current area.
