Freeport, Illinois is currently assigned two area codes 779 and 815. Freeport, IL utilizes an area code overlay in which
area codes 779 and 815 serve the same geographic area. The area code overlay which is in use in Freeport, IL today was put into service on March 17, 2007 when area code 779 was created as an overlay of area
code 815. Area code 815 was put into service in 1947 and was one of the four original area codes assigned to Illinois. Ten digit dialing (area code + seven digit number) is necessary in Freeport, IL because
two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
In addition to Freeport, IL area codes 779 and 815 serve the
major communities of Belvidere, Crystal Lake, DeKalb, Joliet, Kankakee, Loves Park, Machesney Park, McHenry, Rockford, Romeoville and Woodstock, along with many smaller towns and communities in northern
Illinois. |
