Area Code 530

Area Code 530 History:

11/01/1997
Area code 530 was officially put into service. Area code 530 was created from a split of area code 916.

The California Public Utilities Commission on August 08, 2023 approved area code 837 as an all services overlay of area code 530 with an implementation date of 01/31/2025. Area code 837 will only become available to subscribers when all assignable central office codes in area code 530 are assigned. Ten digit dialing (area code + seven digit number) will be necessary in the 530/837 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.
