Preregistration is a policy that allows eligible people as young as 16 to sign up to be registered to vote once they turn 18. Most states that allow preregistration will add applicants to voter lists under a pending status, which is then updated to active when the voter turns 18. Preregistration increases turnout and engagement for young voters, who are historically the least likely to exercise their right to vote.
