Find any 707- phone number in California
The 707 area code is an area code that is used throughout parts of California. It is part of the North American Numbering Plan (NANP) and covers most of the North Coast region of the state, as well as portions of the capital, Sacramento.
The NANP is an integrated public number plan in North America that allows telephone users to dial 10-digit local telephone numbers to make calls from one area code to another. It also uses three-digit area codes to define the geographic boundaries of the telephone networks in specific regions, which is how the 707 area code was formed. The 707 area code serves most of the population in California’s North Coast region, including parts of the capital Sacramento. It also covers certain portions of the state's Pacific Northwest and Central Valley regions.
