Whether you need to bring ID to the polls depends on if you need to register at the polling place or not.
If your voter registration is current and active, you do not need to bring identification. This means you were successfully registered at least 21 days before Election Day and you have not moved or changed names since then.
If you need to register or update your registration, or you have not voted in four years or more, you will need to show proof of residence before you vote.
