When you register to vote, your local election official will send you a notification letter or voter ID card that will indicate the location of your polling place. Since polling place locations can change before the election, it is always a good idea to double check with your local elections office. In most states you can do this online.
Go to the Election Official Directory. Choose your State and Region to find the link to your Local Elections Website.
If your region does not have a website, you will have to contact your local election official. This information can also be found on the Election Official Directory.
