Don't forget! Beginning October 24, 2021, callers must dial 10 digits (area code + telephone number) for all local calls. On and after this date, local calls dialed with only 7 digits may not be completed and a recording will inform you that your call cannot be completed as dialed. You must hang up and dial again using the area code and seven-digit number.
