Before 1951, all long distance phone calls required an operator’s assistance. Once operators were cut out of the equation, the phone system’s infrastructure was in need of an organized routing system. Since everyone used rotary phones, area codes were given out with dialing speed in mind. The bigger the city, the less time you have to wait for the numbers to loop around. New York’s 212 took only 5 clicks to register while Nova Scotia’s 902 took a whole 21.
Until recently, all area codes had either a 1 or a 0 in the middle number so local calls could still be dialed without the area code. (The central computer was programmed to know that a second digit of 0 or 1 meant an area code, so it would wait to receive all ten digits before making the call.) However, the addition of cell phones and countless new phone numbers made this an impossible standard to keep up.
