650 was split from 415 and entered service on August 2, 1997. The part of the old 415 area just south of San Francisco took the new code, and San Francisco and Marin County kept 415.
A plan to lay a second code, 764, over 650 was approved in 1999 and suspended that December, and no second code is in service. Calls inside the area could be dialed with seven digits until October 24, 2021, when ten-digit local dialing became mandatory. Today a local call is dialed as 1 plus all ten digits.
