You may register to vote by appearing in-person at a voter service and polling center through Election Day.
You may change or withdraw your party affiliation no later than 29 days before the election.

Registered voters are required to present one of the following forms of identification at their polling places.

Are You Still Registered?

You are registered if you voted in the last general elections and have not moved, or if you have registered since that date. If you have moved, you are required to change your address with the County Clerk. If you did not vote in the last two general elections, you may be declared "inactive" and may need to re-register or reactivate your voting status. Verify your status with the County Clerk at least 29 days prior to Election Day or online (see above).
