650 Area Code in California, United States

Description

Area code 650 serves the San Francisco Peninsula, including cities such as Palo Alto, San Mateo, Redwood City, and Mountain View. It was created in 1997 as a split from area code 415 to accommodate the growing tech industry in Silicon Valley. The 650 region is home to Stanford University and the headquarters of major tech companies like Google and Meta (formerly Facebook). This area code is strongly associated with innovation, entrepreneurship, and high-tech culture. Despite increasing demand, 650 has remained a standalone code without an overlay, although ten-digit dialing may eventually be required. It’s frequently referenced in tech industry culture and is a point of regional pride. The 650 area is among the most affluent and connected in the country, making the area code a symbol of global technological leadership.
