This is a list of area codes in California and when they were created:

  • Note: Exchange boundaries do not follow city or county boundaries; many of the area codes include or exclude slivers of the cities or counties listed above. For example, the boundary between 562 and 714 generally follows the boundary between Los Angeles and Orange Counties, but portions of Los Angeles County are in 714 and portions of Orange County are in 562. Similarly, most of Daly City is in 650, but a small portion is in 415.
