Area code 650

Encyclopedia : A : AR : ARE : Area code 650

North American area code 650 is a state of California telephone area code which includes most of San Mateo County (except the northernmost portion) and the extreme northwestern portion of Santa Clara County including Palo Alto.

The 650 area was created by moving prefixes out of the 415 area code. A six month "permissive dialing" period where either area code would work began August 2, 1997. Mandatory dialing of the new area code started on January 31, 1998.
