Who can vote in U.S. elections? Generally, if you’re a U.S. citizen and at least 18 years old, you can vote. But each state can impose its own requirements and restrictions on voting. In most states, people incarcerated for felony crimes cannot vote. And most states require people to register their names and addresses in advance of an election, with deadlines spanning from three to 30 days ahead of time. Three-fourths of states ask for some form of identification at the polls, including 21 that require a photo ID.
