My grandparents lived in a small east Texas town. To call some one you would dial 5 numbers. My grandfather would not spend more than 2 minutes on the phone because “central was listening”. He lived from 1903 to 1981.

Grandpa B was 927J2.
Grandpa W was 903R1.
You didn’t dial — no dials. You just picked up the receiver and told Mabel.
