Area Code 805 History:
Area code 805 was officially put into service. Area code 805 was created from a split of area code 213. In 1999 area code 805 was split to form area code 661.
On June 30, 2018 area code 820 was officially put into service as an all services overlay of area code 805. Effective 06/02/2018 ten digit dialing (area code + seven digit number) became necessary in the 805/820 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.
