What are the first 3 digits of an on-campus (resident) phone number?
If you are calling from off-campus, the first three digits of an on-campus resident phone number are 612. For a non-resident on-campus number, it is 568. Remember, if you are dialing from a campus phone, you only need to dial the last four digits of the phone number, preceded by a “2” for on-campus student numbers, or an “8” for offices on campus.
