Voter registration options in every state

In addition to the traditional method of in-person registration, many states offer online registration, same-day voter registration, and automatic voter registration. Same-day voter registration allows people to vote on the same day they registered early voting periods and in many states even further election day.

About half of states offer automatic voter registration. This means that individuals are automatically registered to vote when they contact certain government agencies, such as the Department of Motor Vehicles, and receive a driver's license or ID card. Anyone who would like to unsubscribe from automatic registration can do so. The Center for Election Innovation & Research, led by Becker, offers further information on registration and deadlines for the 2024 elections.
