    TIPS for Ease of Voting on Election Day

    • If you come in person, be sure to remember your District Number as recorded on your sample ballot.  This will help ensure that social distancing requirements are met and a quicker voting process.

    • It is always a good idea to bring identification and proof of address with you when you go to vote, especially if you are voting for the first time. If you registered by mail, you may need to bring a photo ID, utility bill, paycheck, or other document showing your name and address.

    • The process will be slightly different if you use Early Voting from voting on Election Day. Please note in the descriptions above.
