# California Area Code 916
The 916 area code serves the Sacramento metropolitan area and surrounding regions of Northern California, covering the state capital and its suburbs. This area code was established in 1957 as part of the original North American Numbering Plan (NANP) implementation and has remained one of California's most significant regional designations. The 916 area encompasses Sacramento County and portions of neighboring counties, serving a population of over 2 million residents. Major cities within this region include Sacramento, Folsom, Elk Grove, and Roseville, making it a hub for government, technology, and business activities in Northern California.
The North American Numbering Plan is a standardized telephone numbering system that assigns unique three-digit area codes to geographic regions across North America, including the United States, Canada, and other territories. This system was designed to facilitate efficient telephone routing and identify calling regions for billing and regulatory purposes. Area codes are allocated by the North American Numbering Plan Administrator (NANPA), a neutral third party that manages the assignment of codes to telecommunications carriers and service providers. The system uses a hierarchical structure where the first digit indicates the geographic region, and subsequent digits identify specific service areas, allowing millions of telephone calls to be properly routed across the continent daily.
