Ten-digit and seven-digit dialing in 971

According to NANPA's dialing-plan data, local calls within 971 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number.
