Area code 209 is the California telephone area code that was split from area code 415 on October 26, 1957. It covers Stockton, Modesto, Turlock, Merced, Winton, Atwater, Livingston, Manteca, Ripon, Tracy, Lodi, Galt, Sonora, Los Banos, San Andreas, Mariposa, and Yosemite, the northern San Joaquin Valley (part of California's Central Valley), and the Sierra Foothills.
The southern half was split into area code 559 on November 14, 1998.
Central office prefixes of area code 209 are expected to be exhausted by late 2022.
Area code 209 has telephone numbers assigned for the central office code 988. 988 has been designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which creates a conflict for exchanges that permit seven-digit dialing. This area code is therefore scheduled to transition to ten-digit dialing, mandatory after October 24, 2021.
