A voter registration campaign or voter registration drive is an effort by a government authority, political party or other entity to register to vote persons otherwise entitled to vote. In some countries, voter registration is automatic, and is carried out by the government, so there is no need for organized efforts to register voters. In many many jurisdictions, the functions of electoral authorities includes endeavours to get as many people to register to vote as possible. In most jurisdictions, registration is a prerequisite to a person being able to vote at an election.
