We did growing up... it was exhausting calling someone with a lot of 7s, 8s or 9s in their phone number! I remember reading that the cities with the most call volume got the lowest digit area codes... that explains the 212 where I live and the 703 where I grew up.

Did you have a rotary phone growing up? Growing up, did your home phone number have any 7s, 8s or 9s?
