I remember in the small town where I went to college (in the 70's) there was what we called the "beep line" where there was a particular number you could call that returned a slow busy signal, and you could say things in between the beeps that everyone dialed in could hear. It was a way to meet girls. Sort of a early version of facebook I suppose.
Also, at some point in the late 70's or 80's the phone company decided to convert all the alpha prefixes into the numeric equivalents. So you didn't get a new number, it was just written down as all numeric.
The prefixes were very geographic, so everyone living in your neighborhood had the same prefix. If you moved to a new neighborhood in the same town, you had to get a new phone number. I think even if you moved across the street you had to get a new number. You could tell what part of town someone lived in based on their phone number prefix. This continued even when they dropped the alpha prefixes.
