United States Election Assistance Commission (EAC)
One of EAC’s primary mandates under the Help America Vote Act is to serve as a central resource for information about elections. Through EAC’s national clearinghouse, the public will find information about topics such as registering to vote and serving as a poll worker along with studies on how, where and when we vote.
EAC is also responsible for maintaining the National Mail Voter Registration form (formulario nacional de inscripción de votantes), which can be used in any state to register to vote in a federal election. EAC also provides information about registering to vote and contact information for each state election office.
