California Area Codes

Which California Area Code Covers Where

14 of California's area codes share territory with another. Codes in the same row serve the same places, so either can reach a number there — and ten-digit dialling is required throughout.

How California Got Its Area Codes

California went from 3 area codes in 1947 to 41 today. A split carves territory off its parent; an overlay sits on top of it, which is why newer codes need ten-digit dialling.

California Numbering Structure

Recent Overlays — Ten-Digit Dialing

California has had 29 area codes activated as an overlay since 2021, sharing territory with an existing code rather than carving out new geography. Local calls in an overlaid region must be dialed with all ten digits. Earlier overlays are not listed here.
