Area codes 760 and 442, Telephone area codes in Southern California, United States.
Area codes 760 and 442 apply to southeastern California and cover several counties, including Imperial, Inyo, and parts of Riverside. The territory ranges from desert regions to mountain towns, connecting remote communities with larger settlements near the Nevada and Arizona borders.
The California regulatory body introduced 760 in 1997 when the previous numbering area 619 was divided. Code 442 came later as an overlay to meet growing demand for new numbers in the same region.
The telephone codes serve diverse communities from Palm Springs to Bishop, connecting desert settlements, mountain towns, and coastal neighborhoods.
Anyone dialing within these code areas must always use all ten digits, meaning the code followed by the seven-digit number. This applies even when calling neighbors in the same town, since both codes cover the same geographic space.
These codes serve the largest numbering territory by area in California, spanning landscapes from low basin floors to high mountain ranges. A single calling zone thus connects places with extreme elevation differences and entirely different climates.
