The 510 area code was created in 1998 as a split from the original 510 that once covered all of Alameda County. Today, 510 is exclusively tied to Alameda County, located in the heart of the San Francisco Bay Area. It covers iconic neighborhoods like:
Oakland – the vibrant heart of the county
Fremont – a diverse and growing city
Hayward – known for its rich culture and history
For generations, 510 has represented local pride, offering the best of community life with fast access to all nearby areas.
The 510 area code operates in the Pacific Time Zone (PT)–the same time zone as Alameda County. This is important for businesses and professionals who need to stay in sync with local clients, suppliers, and partners. Whether you’re scheduling calls, running local ads, or managing customer support, having a 510 number means you’re aligned with Pacific Standard Time (PST) in winter and Pacific Daylight Time (PDT) in summer.
The 510 area code covers all of Alameda County, including:
Oakland
Fremont
Hayward
and many more.
Getting a 510 number gives your calls a familiar, local presence in one of Alameda County’s busiest urban regions. It’s perfect for real estate agents, freelancers, remote workers, and anyone who wants to appear local while staying flexible.
