States that allow same-day voter registration

Twenty-three states and Washington D.C. permit same-day voter registration, allowing individuals to register and vote on Election Day, November 4, 2025. This option is available in states like Alaska and Rhode Island, though some have restrictions, such as only applying to presidential elections or being limited to early voting periods. Voters in New York City, New Jersey, Virginia, and California are among those participating in elections where same-day registration may be an option.
