About the 618 area code
Phone numbers that start with 618 come from Illinois, where the code reaches Belleville, Alton, Granite City, East St. Louis, and Edwardsville. Central time prevails across the territory.
618 counts among the area codes first assigned in 1947. Its boundaries have never been split, though the code no longer stands alone; 730 covers the identical territory as an overlay partner, and the pairing means every local call is dialed with ten digits.
Dialing note: 618 is part of an overlay complex with 730, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
