Voter Information

To update your record or register for the first time, voter registration is open all year except for the 27 days preceding an election, and it reopens the second day following an election. After voter registration closes, Grace Period Registration begins 27 days before any election, and you are required to vote at the time of your registration. You must register with the Election Officials at polling places during the Grace Registration Period.

While voter registration is open, you can register in-person, online, or by mail. See updated voting by mail instructions below.
