Ten-digit and seven-digit dialing in 838
According to NANPA's dialing-plan data, local calls within 838 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.
