Register to vote online at gottavote.org.
Once your voter registration goes through, you should receive what’s called a “sample ballot” in the mail that will tell you your polling place, which is where you have to go to vote.
If you don’t get your sample ballot within about a month of registering, check canivote.org to see if your registration went through. Even if you never receive your sample ballot, go to your polling place on election day with your ID and ask to vote. If they don’t have you registered, you should be able to fill out a separate type of ballot.
Voting from abroad? There’s a site for that.
Moved recently (for college or otherwise) or moving before the election? There’s a site for that. Specifically, there’s a form you have to fill out to update your registration. Even if you moved somewhere within the same district or ZIP code, you need to re-register!!!
