Feature Answer

What is Area Code 650?

Area code 650 is a North American telephone area code assigned to San Francisco Peninsula, covering Palo Alto, Mountain View, Redwood City. It was created in 1997 when area code 415 was split to handle growing demand. The code is local rather than toll-free, and it operates on Pacific Time.

Before 1997, San Francisco Peninsula was part of the larger 415 footprint. As the region grew, the FCC carved out 650 to serve its own community, leaving 415 to anchor a more focused area. Today 650 is the recognized code for San Francisco Peninsula, used across local businesses, institutions, and households.
