About the 779 area code
Area code 779 reaches the Illinois cities of Rockford, Joliet, and DeKalb. Every community within its boundaries runs on Central time.
Brought into service in 2007, the code was laid over the existing 815 area as an overlay, covering precisely the same ground rather than splitting it. For anyone with a number in either code, a local call means entering all ten digits.
Dialing note: 779 is part of an overlay complex with 815, 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.
