Growing up in Illinois in the '70s that was the "time and temperature" number. It was also the fake number you gave out if people asked and you didn't want them to get your real number.
Found the person who grew up in (probably southern) California.
Bingo. I miss her along with 411 and calling my parents with the collect call name "QualcommStadiumGameOverPickMeUp"
I really miss payphones and the death of the not always connected world.
This was all over the US, but the number may have been different.
