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
    
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.
Prior to October 2021, area code 530 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 permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.[1]
