Iowa has both caucuses and primaries. Caucuses are run by political parties and are used primarily to select delegates from the local to the national level who then represent voters’ preferences in terms of presidential candidates and party issues. Primaries are run by the state, where voters cast secret ballots in order to elect officials in all races excluding presidential.

Iowa has closed caucuses. Voters must be registered with a party in order to attend that party’s caucus.

Iowa has closed primaries. Voters registered with a particular party may only vote in that party's primary. Primaries are run by the state, where voters cast secret ballots in order to elect officials in all races excluding presidential. 17-year-olds can vote in the primary election if they will be 18 by the corresponding general election.

Any registered voter who does not have a valid driver's license or non-operator's ID issued by the Iowa Department of Transportation will be issued a Voter ID Card for free, automatically, in the mail. This also applies to anyone who registers to vote in the future. Upon receipt of the Voter ID Card, it should be immediately signed.

If you go to your polling place without an approved form of ID, another registered voter in the precinct may attest to your identity. You can also register on Election Day without the required ID if another registered voter in the precinct attests to your identity. Voters without the necessary ID or an attester will be offered a provisional ballot and can provide ID up until the time of the county canvass of votes (Monday after election day for Primary and General Elections).
