County of Kent recently issued the following announcement.
Beginning Oct. 24, 2021, all consumers with numbers in the 616, 810, 906 and 989 area codes must dial 10 digits for all local calls. Beginning that day, local calls dialed with only 7 digits may not be completed, and a recording may inform you that your call cannot be completed as dialed. If you get this recording, you must hang up and dial again using the area code with the 7-digit telephone number.
