According to a recent report from the National Council of State Legislatures only 24 states currently require voters to provide identification prior to voting. Seven of those states specify that voters must show a photo ID; the other seventeen states accept additional forms of identification that do not include a photo. (See table below.) However, all these states have some sort of recourse for voters without identification to cast a vote. In Georgia and Indiana, voters without identification can cast a provisional ballot, but must return to election officials within a few days and show a photo ID in order for their ballots to be counted.

Note: The federal Help America Vote Act mandates that all states require identification from first-time voters who registered to vote by mail and did not provide verification of their identification with their mail-in voter registration.
