Area Code 217 History:
Area code 217 was officially put into service on 01/01/1947. In 1957 area code 217 was split, along with a portion of area code 815, to form part of area code 309.
Area code 447 was put into service as an all services overlay of area code 217 on 03/27/2021. Ten digit dialing (area code + seven digit number) became necessary in the 217/447 overlay effective February 27, 2021 because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
