To register, a person must have his or her name on the official voter's list. This is usually easy to do. In many states, people can register at libraries, stores, schools and other public places. In some places, people can register by mail. Although registration is a little bit different in some states, in most places it just means that a potential voter needs to show proof of his or her identity and residence and sign a paper.
Registration puts each voter's name on a list.
Each area also has a special place set up for voting. People may vote only at the particular place near where they live. When they go to that place to vote, someone will check off their name on the list and make sure each person votes just once.
