Telephone area code in
Florida. At the inception of the
North American Numbering Plan in 1947, 305 covered the entire state from
Pensacola to
Miami. 305 was divided into three area codes in the 1960's: the new 305 covered
South Florida and the
Space Coast, while
904 covered northern Florida and
813 covered southwest Florida.
There are now seventeen area codes in Florida. As they were created, 305 progressively shrank, first to the size of South Florida, and then to the size of Miami-Dade and Monroe counties. Now those areas are overlaid by the 786 area code, which is not that common, yet, but grows at an incredible pace.
305 is in many ways a testament to the population explosion in Florida following World War II.
