Arizona Proposition 144 Would Require Government-Issued ID for Mail Voting Starting in 2028

By SNN Newsroom | October 15, 2026

Arizona voters will decide a proposed constitutional amendment on November 3 that would require government-issued identification for voting in each election, including voting by mail. Proposition 144 also addresses Election Day ballot counting, foreign campaign contributions and the legal standards courts would apply when reviewing election laws.

The measure originated as House Concurrent Resolution 2001, approved by the Legislature for referral to voters. The Secretary of State’s official ballot language states that a “yes” vote would add the identification requirement and make other constitutional changes, while a “no” vote would preserve the existing constitutional provisions.

What would change

Under Proposition 144, every voter would need to present valid government-issued proof of identity before casting a ballot, whether in person or by another permitted method. The Legislature would determine implementation details under subsequent law; the official measure does not establish a finalized new mail-ballot verification procedure.

The amendment would also require voters to have an option to tabulate their ballots at their voting location on Election Day. It would bar foreign nationals from making contributions or expenditures to influence Arizona elections and prohibit knowing acceptance of those funds, paralleling prohibitions already found in federal law. In addition, it would establish a different standard for reviewing election statutes under Arizona’s constitution and require state funding for implementation.

The Arizona Legislative Council’s nonpartisan analysis specifies that the new provisions would apply to elections on or after January 1, 2028. The November 3, 2026 election itself would continue under current requirements.

Arguments and uncertainties

Supporters argue that uniform identification rules and election administration provisions would improve confidence and consistency in elections. Critics warn that applying an in-person-style proof-of-identity requirement to mail voting could create new barriers or complications for voters. Implementation depends on future legislation, so claims that the measure definitively ends mail voting—or guarantees a particular new way of verifying mail ballots—go beyond the enacted text of the proposal.

Arizona voters who plan to vote in this year’s election can consult the state’s Citizens Clean Elections Commission for their current voting options. According to that resource, early voting began October 7; October 23 is the last day to request a ballot by mail; and October 30 is the final day for early in-person voting. Election Day is November 3.
