Origin Story
Area code 650 was created on August 2, 1997, when it was split from the original 415 area code. The split was necessary due to the rapid growth of the San Francisco Bay Area and the increasing demand for telephone numbers. Initially, 650 covered most of San Mateo County and parts of Santa Clara County. Over the years, the region's explosive growth in technology and business has made 650 one of the most sought-after area codes in the United States. The area code has become synonymous with Silicon Valley innovation, housing headquarters of major tech companies and startups alike. In 2015, an overlay area code (424) was added to the 415 region, but 650 remains a standalone area code serving its original geographic area. The 650 area code continues to represent the prestigious San Francisco Peninsula and remains a symbol of business credibility and innovation.
