Area Code 209 History:
Area code 209 was officially put into service on 01/01/1958. Area code 209 was created from a split of area code 916. In 1998 area code 209 was split to form area code 559.
Area code 350 was put into service as an all services overlay of area code 209 on November 28, 2022. Ten digit dialing (area code + seven digit number) is necessary in the 209/350 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
