History of 279 Area Code
Area code 279 was created in March 2018 as an overlay to area code 916, which was one of the original three area codes established in California in October 1947. Area code 916 originally covered most of Northern California but was split several times over the years to reduce its coverage to the greater Sacramento area.
Due to the high demand for telephone numbers in this region, area code 279 was introduced to provide more options for customers. The new area code required ten-digit dialing for all calls within and between the two area codes.
