LincMad's Area Codes of the 1970s

The period from 1/1/66 to 11/4/82 - almost 17 years - with only one area code split, was by far the longest period of stability in the history of the North American Numbering Plan. Over 40 new area codes were added during 1997 alone.


my "MYM" banking software, which i used up until i think 1996 or 1997, had a hard-coded business rule that would reject any area code with a middle digit other than "0" or "1"
