In this case, the 217 code has been Overlayed with the 447 area code. New phone numbers in the Mount Olive area will be assigned with one of these codes: 217 or 447. As a result, placing a call in the Mount Olive area will require 10-digit dialing (where you enter both the area code and then the phone number).
