Example of the super-long article enlisted them one by one, but take a shortcut to the 700's and here you find my 760 represents the California Desert and parts of the Inland Empire, Cal. and San Diego area.
California has a total of 30-32(?) telephone area codes, the most of any state.
Formerly it was 213 since the area code system started after WWII (1945) when long distance calling service was pefected, then it was part of 714 (Orange County, San Diego and Riverside) in the 1960s and 70s and 619 (for San Diego) in the mid 1980s to mid 1990s. In around 1990, the Riverside area got 909 and around 2000, it got 951 while 909 still is for the San Bernardino area.
760 is the largest area code in the contiguous US, while 907 of Alaska is the true largest and 780 for Canada covers the sparsely populated Arctic region (Yukon, Northwest Territories and Nunavut).
