Idaho: Do you need an ID to vote?
Idaho asks voters for a photo ID, but a voter without one can sign an affidavit at the polls and vote a regular ballot.
Accepted IDs are an Idaho driver's license or ID card, a U.S. passport or other federal photo ID, a tribal photo ID, or an Idaho concealed weapons license. Student IDs are not on the current list. Since July 1, 2026, the affidavit must include the voter's name, address, and either date of birth or Idaho license or ID number, and poll workers check that information against registration records before handing out a ballot. Knowingly giving false information on the affidavit is a felony.
Conditions
- Affidavit must list name, address, and date of birth or Idaho license/ID number
