Phone numbers with the 650 area code prefix originate from San Mateo County, portions of San Francisco, and the northwestern part of Santa Clara County in California. It was split from area code 415 on August 2, 1997.
No, 650 is a legitimate California area code covering most of San Mateo County and parts of Santa Clara County, including Palo Alto, Redwood City, and Mountain View. Fraudsters frequently spoof this specific prefix because it is associated with major tech hubs, which often makes recipients more likely to trust a call appearing to originate from Silicon Valley.
The concentration of global tech giants in the 650 region makes it a prime target for high-stakes account security fraud. Many residents report a sophisticated Google security scam where a caller named "Glen King" or an automated assistant claims your Gmail is compromised to trick you into approving a malicious login. Additionally, fake medical billing texts referencing Dr. Beth Moore or local COVID-19 testing sites are used to harvest credit card data through fraudulent $1.07 test charges.
