How calls are dialed in 845

According to NANPA's dialing-plan data, local calls within 845 are dialed as ten digits (area code plus number) and toll calls as ten digits (area code plus number). Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "1+10 digit permissible at service provider discretion."
