The Ins and Outs Of Voter Registration

Requirements under Title III of HAVA set national standards for what the types of identification voters (especially first-time voters and those who do not include some form of ID when registering by mail) need to bring to the polls. HAVA mandates that states require first-time voters who registered by mail to show one of a number of forms of ID when they vote at the polls, if they did not include verification when registering. HAVA ID requirements also extend to those that have not previously voted in election for federal office in the state or in the jurisdiction.
Acceptable forms of ID include:
current and valid photo identification (government issued photo ID) or
a copy of a current utility bill, bank statement, government check, paycheck, or other government document that shows the name and address of the voter.

Different states will have different requirements.
