My Enterprise number for Konawa, Oklahoma, was Enterprise 287, as I recall. It terminated on my business number, 234. Yes, 234 was a local number in a dial exchange. Terminal-per-line. Party lines had four digit numbers in the 4xxx series, the last digit denoting the party ringing.
Three- and four-digit Enterprise numbers were not unusual in those days.
