You can find your local polling place by contacting your local or state board of elections. Many states have easy-to-use polling place locators built into their websites, but you can also get polling place information over the phone.
The U.S. Election Assistance Commission website links to all state board of elections websites. On some state websites, you can enter your name and address and quickly receive your polling place information. Each individual state or territory's website also includes office contact information so you can speak directly with a local board of elections staff member about finding your polling place. Many states require voters to register to vote in advance of an election. If you're not yet registered, find more information about completing the registration process via your local board of elections website or by contacting the office directly.
