About the 820 Area Code

California's 820 area code is a recent overlay layered onto the Central Coast region long served by the 805, with Oxnard as the directory's anchor city. Oxnard sits on the wide coastal plain of southern Ventura County, organized around a port, a working downtown, and surrounding strawberry and citrus fields that extend almost to the ocean. The 820 designation, part of the North American Numbering Plan, is being filled gradually as number demand pushes new allocations into the Central Coast region.

A range of other California cities — Anaheim, Bakersfield, Chico, Concord, and others — appears in the directory's records linked to 820 numbers. None of those are inside the 820 footprint. The pattern reflects California's high number mobility through porting, prior registration, and the public-record sources that cross-link addresses across cities. As an overlay still in early circulation, 820 has only a limited prefix presence in the directory — 3 distinct prefixes documented in detail — and that figure represents our current coverage rather than the live total.

Oxnard's home values come in well above the US median, in line with the broader Central Coast housing pattern. Median household income runs above the national reading, the city's median age sits in the low thirties (under the US figure), and the population places Oxnard among the larger Ventura County cities — large enough to anchor a regional economy that combines agriculture, commercial fishing, port traffic, and a substantial commuter share into the Los Angeles area.
