About the 510 area code
Oakland, Berkeley, Richmond, Fremont, and Hayward share California's area code 510, whose territory lies in the Pacific time zone.
Numbering here dates back to 1991, when 510 was created on ground formerly tied to area code 415. Area code 925 was later split out of the territory, and 341 now functions as an overlay across what remains, which keeps local dialing at the full ten digits.
Dialing note: 510 is part of an overlay complex with 341, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 10/08/2026.
