510 Area Code in California, United States

Description

Area code 510 covers the East Bay region of the San Francisco Bay Area in California, including cities such as Oakland, Berkeley, Fremont, and Hayward. Created in 1991 as a split from area code 415, 510 serves a diverse urban and suburban population. This area is known for its cultural vibrancy, progressive politics, and major academic institutions like the University of California, Berkeley. In 2019, area code 341 was introduced as an overlay, requiring ten-digit dialing throughout the region. The 510 area code has long been associated with activism, innovation, and a rich mix of cultures. Despite the overlay, 510 remains a strong regional identifier and is often referenced in music, sports, and local branding. It captures the spirit of the East Bay’s historic and evolving identity.
