Area code 530 is a telephone area code in the North American Numbering Plan (NANP) in northeastern and Northern California. It was created in 1997 in an area code split of 916.

Contents

The numbering plan area (NPA) includes the Sacramento Valley (including some outer suburbs of Sacramento), Shasta Cascade, and the northern Sierra Nevada. It comprises all or sections of the following counties: Alpine, Butte, Colusa, El Dorado, Glenn, Humboldt, Lassen, Modoc, Mono, Nevada, Placer, Plumas, Shasta, Sierra, Siskiyou, Sutter, Tehama, Trinity, Yolo, and Yuba.

History

Area code 530 was created in a split of numbering plan area 916 on November 1, 1997. Simultaneously, the Dixon exchange was reassigned from area code 916 to area code 707, and from the Sacramento Local access and transport area (LATA) to the San Francisco LATA.

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]

On June 8, 2023, the California Public Utilities Commission assigned Area code 837 as the overlay area code for 530, effective January 31, 2025. [2] 837 will serve as California's 40th area code. As ten-digit dialing is already in effect, no permissive dialing period will be necessary. [3]

Service area

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

The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California. The river's main stem is about 73 miles (117 km) long. Its length to its most distant headwater tributary is just over 210 miles (340 km). The main stem Feather River begins in Lake Oroville, where its four long tributary forks join—the South Fork, Middle Fork, North Fork, and West Branch Feather Rivers. These and other tributaries drain part of the northern Sierra Nevada, and the extreme southern Cascades, as well as a small portion of the Sacramento Valley. The total drainage basin is about 6,200 square miles (16,000 km2), with approximately 3,604 square miles (9,330 km2) above Lake Oroville.

<span class="mw-page-title-main">California State Route 89</span> Highway in California

State Route 89 is a state highway in the U.S. state of California that travels in the north–south direction, serving as a major thoroughfare for many mountain communities in the Sierra Nevada and the Cascade Range. It starts from U.S. Route 395 near Topaz Lake, winding its way up to the 8,314-foot (2,534 m) Monitor Pass, down to the Carson River, and up again over the 7,740-foot (2,359 m) Luther Pass. From that point on, the route generally loses elevation on its way past Lake Tahoe, through Tahoe and Plumas National Forests until Lake Almanor. For roughly nine miles the route is then a part of State Route 36. The route then ascends to the 5,753-foot (1,754 m) Morgan Summit. After it enters Lassen Volcanic National Park it continues to gain elevation until it reaches its highest point in an unnamed pass in the middle of Lassen Peak and Bumpass Mountain. The road then descends and heads northwest, finally terminating at Interstate 5 at the foot of Mount Shasta at around 3,600 feet (1,100 m).

<span class="mw-page-title-main">North Fork Feather River</span> River in California, United States

The North Fork Feather River is a watercourse of the northern Sierra Nevada and southern Cascades in the U.S. state of California. It flows generally southwards from its headwaters near Lassen Peak to Lake Oroville, a reservoir formed by Oroville Dam in the foothills of the Sierra, where it runs into the Feather River. The river drains about 2,100 square miles (5,400 km2) of the western slope of the Sierras. By discharge, it is the largest tributary of the Feather.

<span class="mw-page-title-main">Feather Headwaters</span>

The Feather Headwaters is the watershed of the Feather River above Lake Oroville, totaling 3,450 sq mi (8,900 km2). Subdivided into 3 watersheds, the North Fork Feather Watershed is 1,090 sq mi (2,800 km2)—including the West Branch drainage of about 282.5 sq mi (732 km2), the East Branch North Fork Feather Watershed is 1,010 sq mi (2,600 km2), and the Middle Fork Feather Watershed is 1,350 sq mi (3,500 km2)—including the South Fork drainage of about 132 sq mi (340 km2). Headwaters drainage is impaired by the Palermo Canal at Oroville Dam, the Hendricks Canal at the West Branch Feather River, and the Miners Ranch Canal at the South Fork's Ponderosa Reservoir. Additionally, the Pacific Gas and Electric Company releases Upper Feather water into the Hyatt Generating-Pumping Plant for hydroelectric generation during daily peak demand.
