Q.

What is Voter ID?

A.

Starting in 2019, voters must provide an ID when going to vote. Pre-Registered voters who do not have an acceptable form of ID will be allowed to cast a provisional ballot. Election Day registrants who do not have an acceptable form of ID will be allowed to either cast a provisional ballot or have another registered voter from your precinct may attest to their identification. Learn more about provisional ballots and attesting on our Voter ID page.

There are 6 approved types of identification that may be used:

  • an Iowa Driver’s License or Non-Operator ID
  • a Voter ID issued by the Secretary of State or the Auditor’s Office
  • a current US Passport
  • a US Military ID
  • a US Veteran’s ID
  • a Tribal ID
