The first three numbers in brackets of a 10-digit phone number represent the area code for California.

The State of California is given authority by the FCC to decide whether to add new area codes or overlap current area codes in the state. New area codes created by the NANPA are to be announced to state citizens by the California Public Utility Commission (CPUC).
