The 650 area code was created in 1997 as a split from the original 415 that once covered all of the San Francisco Peninsula. Today, 650 is exclusively tied to San Mateo County, located on the San Francisco Peninsula. It covers iconic neighborhoods like:
Palo Alto – home to Stanford University and vibrant tech companies
Redwood City – known for its diverse dining and entertainment options
Menlo Park – a hub for innovation and technology
For generations, 650 has represented pride in the region, offering the best of Silicon Valley with fast access to all local resources.
The 650 area code operates in the Pacific Time Zone (PT)–the same time zone as San Mateo 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 650 number means you’re aligned with Pacific Standard Time (PST) in winter and Pacific Daylight Time (PDT) in summer.
The 650 area code covers all of San Mateo County, including:
Palo Alto
Redwood City
Menlo Park
and many more.
Getting a 650 number gives your calls a familiar, local presence in one of California’s busiest urban regions. It’s perfect for real estate agents, freelancers, remote workers, and anyone who wants to appear local while staying flexible.
