Counties on the eastern shore of the San Francisco Bay covered by Numbering Plan Area 510 have a new overlay area code starting July 22, 2019. The new 341 NPA was announced about a year prior to its activation by the California Public Utilities Commission (CPUC). Telephone calls in the newly created overlay complex 510/341 are now to be dialed using 1+10 digits for both local and toll calls.
