As an aside, I recall watching cartoons as a child where anytime they mentioned a phone number it was KL5-something ("Klondike 5"). I guess that is the equivalent to today's "555" prefix, a generic prefix that perhaps never existed in real life.
In the Seinfeld episode "The Big Salad", Elaine (Julia Louis-Dreyfus) gives her phone number as "KL5-2390" and Jerry (Jerry Seinfeld) protests that's actually his number.
