What is the 510 Area Code?

The 510 Area Code is one of California’s area codes belonging to the western vicinities of Alameda and Contra Costa counties in California. It includes such big cities as the busy port of Oakland, academic Berkeley, and tech-promising Fremont.

The 510 area code is under the North American Numbering Plan Administration (NANP), and it is a good instrument for any firm that would want to reach out to this vibrant population.

The area code 510 came into existence in September 1991 from a split with the 415 area code, which had once been served primarily by Pacific Bell. To meet the telecommunications industry’s need for numbers, the 341 area code was added as an overlay in 2019, serving the same geographic region as 510.
