Numbering plan areas in California (blue) and border states. Area code 209 is shown in red.

Area code 209 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of California. Its service area includes 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 the Central Valley), and the Sierra Foothills.

The area code was created in an area code split from area code 415 on October 26, 1957.

The southern half of the original numbering plan area was split off and integrated into area code 559 on November 14, 1998.

The area code is set to be overlaid by new area code 350 in late 2022 as central office prefixes of area code 209 are expected to be exhausted by the fourth quarter of the calendar year.[1] [2]

On October 24, 2021, area code 209 was transitioned to ten-digit dialing, despite not being part of an overlay numbering plan, in which multiple area codes are assigned to a numbering plan area. The area code had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that still permitted seven-digit dialing.[3]
