Area code 805, Telephone prefix in California, United States
Area code 805 serves phone lines in Santa Barbara, Ventura, and San Luis Obispo counties across central California. This zone runs along the Pacific coast and reaches inland toward the foothills.
California's telephone authority introduced this code in 1957 to handle the rising number of subscribers. It split off from the original 213 code that covered the greater Los Angeles area.
The telephone prefix connects multiple communities across central California, from university towns to agricultural centers and coastal settlements.
Callers within the region dial ten digits for local calls because of overlapping codes. Callers outside these three counties place a 1 before the full number.
One number under this code connects callers to a military post on Kwajalein Atoll in the Pacific. This link runs through a Paso Robles exchange for satellite communications.
