On November 28, 2022, the 209 numbering plan area was assigned a second area code, 350 , to form an overlay complex to address impending central office code exhaustion. Ten-digit dialing was already in effect for the 209 area code prior to the introduction of the 350 overlay.
Area code 209 is a general purpose code which was placed in service on January 1, 1958.
