As of March 1, 2018, 37 states plus the District of Columbia and Guam offer online voter registration (OVR). OVR allows those eligible to complete and submit a voter registration application or update to their information entirely online, with no paper involved for the applicant and no returning the form by mail or in person. One state, North Dakota, does not require registration to vote.
The federal election dates and deadlines (XLS) presented on the site were collected from official websites and representatives of chief election offices in all states and territories. See state and local election office websites for more detailed and official information.
