Voters in six states decided ballot measures related to voter identification requirements on Nov. 3. Here are the results and what they mean.

Voters approved three measures and defeated three. All six proposed establishing or expanding voter ID requirements in state constitutions; none proposed reducing or eliminating existing requirements.

Earlier this year, Oklahoma voters approved State Question 846 on Aug. 25, amending the state constitution to require proof of identity for in-person or mail-in voting.

Measures addressing identification for in-person and mail-in voting:

• Arizona Proposition 144: Defeated. Voters defeated a constitutional amendment to require government-issued identification when voting in person or by mail. The measure also addressed citizenship requirements, foreign campaign contributions, and ballot tabulation.
• California Proposition 39: Defeated. Voters defeated a constitutional amendment to require government-issued identification for in-person voting and the last four digits of a designated identification number for mail voting. It also sought to require citizenship-verification efforts, compliance audits, and free identification for eligible voters.
• Nevada Question 7: Approved. Voters approved a constitutional amendment to require photo identification for in-person voting and identity verification for mail voting using the last four digits of a driver’s license or Social Security number, or a number provided by the county clerk.
• North Carolina voter identification amendment: Approved. Voters approved a constitutional amendment to require photo identification when voting in person or by mail.
• Ohio Issue 3: Approved. Voters approved a constitutional amendment to require photo identification for in-person voting and either photo identification or, if authorized by law, a signature and at least one other unique identifier for voting by mail or another method.

Measure addressing identification for mail-in voting:

• Colorado Amendment 84: Defeated. Voters defeated a constitutional amendment to require mail-in voters to provide a signature and either a state identification number meeting federal REAL ID requirements or a Social Security number.

How this year compares: Including Oklahoma, voters decided seven voter ID measures in 2026—the most in a single year. The previous high was three in 2022. From 2004 through 2025, voters approved 10 of 13 related measures and defeated three.
