    The Illinois Commerce Commission is announcing the addition of the 861 area code to counties and municipalities presently served by the 309 area code. The 861 area code will “overlay” the existing territory in order to supplement the telephone number supply. The 861 area code will be available for assignment sometime during late 2022 or early 2023, as the assignable prefixes in the 309 area code are approaching exhaust. The current forecasted exhaust for 309 is during the 4th quarter of 2023.

  • New 730 Area Code is Coming to Southern Illinois
    The Illinois Commerce Commission has announced a new area code is coming to southern Illinois. The new 730 area code will “overlay” the existing 618 area code to address the depletion of prefixes available for assignment within the region. The first prefix in the new area code will not be introduced until after July 7, 2023. The 618 area code covers all or parts of 37 counties in Illinois and includes communities such as Alton, Belleville, Cairo, Carbondale, Centralia, E. St. Louis, Edwardsville, and Marion. The 618 area code is one of the original, eighty-six area codes in the United States, assigned by Bell Laboratories in 1947. It has not undergone any substantive changes to its boundaries since then.
