A ballot box is a temporarily sealed container, usually a square box though sometimes a tamper resistant bag, with a narrow slot in the top sufficient to accept a ballot paper in an election but which prevents anyone from accessing the votes cast until the close of the voting period. A ballot drop box allows voters who have received a ballot by mail to submit it for counting in a self-service fashion. In the United States, ballot boxes are usually sealed after the end of polling, and transported to vote-counting centers.
