History of 805 California

The 805 area code was established in 1957 after splitting from 213. At the time, it covered a much larger portion of Southern California outside Los Angeles.

As population growth increased demand for phone numbers, new splits occurred:

Today, 805 and 820 serve the same geographic area, meaning new numbers may be assigned either code. Because of the overlay, 10-digit dialing (area code + number) is mandatory for local calls.
