949 Area Code: Irvine, California

California's 949 area code covers central and southern Orange County, with Irvine as the primary city. Irvine occupies a substantial slice of the inland Orange County corridor, organized as a master-planned community on what was once the Irvine Ranch — one of the largest Spanish land grants in California — and the city's modern shape, with its grid of villages, business parks, and the main campus of the University of California, Irvine, reflects that origin. The 949 footprint runs from Irvine south through Newport Beach, Laguna Beach, Mission Viejo, and the South County coastal cities down toward the San Diego County line.

Other California cities — Anaheim, Bakersfield, Chico, Concord, and many more — appear in the directory's records linked to 949 numbers. None of those are inside the 949 footprint. The recurrence reflects California's high number mobility through porting, prior registration, and address linkage. The directory currently tracks 501 distinct prefixes within 949 in detail, a working subset of the prefixes the code actually carries.

Irvine's most striking demographic feature is its income profile: median household income runs well above the US figure, supported by the surrounding cluster of corporate headquarters, university research, and finance employment. Home values come in close to four times the national median, among the highest in any major California city outside the immediate Bay Area. The median age skews a touch under the US reading, and the population places Irvine among the larger Orange County cities — sizable enough to anchor a substantial corporate and residential base.
