Iowa primaries are classified as closed, but voters declare or choose a party at the polls on primary day. You vote in only one party’s primary.

Voter ID

Iowa requires an ID to vote in person, and some non-photo IDs are accepted. If you don’t have acceptable ID, you can vote a provisional ballot, but you must take extra steps after Election Day for it to count.

Early voting

Starts: Twenty days before election (in-person absentee). Ends: 5 p.m., day before election. Locations and hours are set locally.

Voting by mail

Any Iowa voter can request an absentee/mail ballot. No excuse is needed.
