What to know before going to vote on Election Day
Do I need a voter ID to vote in Iowa?
Registered voters need to bring one of these documents to vote on Election Day:
- Iowa Driver's License
- Iowa Non-Operator ID
- U.S. Passport
- U.S. Military ID or Veteran ID
- Iowa Voter Identification card (must be signed)
- Tribal ID/Card document (must be signed, with photo)
What if I’m not registered to vote?
Iowans can register to vote at their polling place on Election Day.
If you don't have one of the forms of ID above, you can bring Election Day registration documents or have another registered voter in your precinct attest to your identity. Attestation will no longer be an option after July 1, when a new state law will take effect.
If you don’t have any of those with you, you can vote a provisional ballot and come back later to provide ID or necessary documents to have your ballot counted.
Iowa Voter ID cards are provided automatically to each voter who doesn't have an Iowa Driver's License or non-operator ID. You can also request one through your county auditor's office.
Early voting ends June 1
Voters can cast their ballots in person at their local county auditor's office or elections office through June 1, the day before Election Day. Every county will have its county auditor's office or county elections office open for early in-person voting through June 1.
Iowans can register to vote online, at their county auditor's office or other early voting location through June 1, or at their polling place on Election Day.
