Code Consistency

The Friday File: Original area codes had either a one or a zero for the second digit. States with one area code had a zero, states with more than one area code had a one. Codes were also designed for rotary phones. The bigger the city, the lower the non-middle numbers, resulting in faster dialing. NYC received 212, Chicago 312, LA 213, and Detroit 313. By contrast, Anchorage got 907.
