Area code 530 is a California telephone area code in northeastern and Northern California.

Regions within it include the Sacramento Valley (including some outer suburbs of Sacramento), Shasta Cascade, and the northern Sierra Nevada. Area code 530 covers all or sections of: Alpine County, Butte County, Colusa County, El Dorado County, Glenn County, Humboldt County, Lassen County, Modoc County, Nevada County, Placer County, Plumas County, Shasta County, Sierra County, Siskiyou County, Sutter County, Tehama County, Trinity County, Yolo County, and Yuba County.

History[edit]

It was split from Area code 916 on November 1, 1997. On the same day the Dixon exchange was moved from Sacramento LATA to San Francisco LATA, and from Area code 916 to Area code 707.

Area code 530 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.[1]

Cities in the 530 area code[edit]

Major cities within the 530 include: Auburn, Chico, Colfax, Davis, Grass Valley, Corning, Marysville, Oroville, Paradise, Placerville, Redding, Red Bluff, Susanville, Truckee, Woodland, Yuba City, and South Lake Tahoe.
