Overview

Voter ID laws have been a central issue in election and voting policy for over two decades and continue to be a focus for policymakers today. These laws require that voters present specific forms of identification when casting their ballot in person.

Voter ID requirements differ significantly across states, ranging from strict photo ID mandates to more flexible alternatives which allow voters to prove their identities in a variety of ways and provide fail-safes for those who may not possess the necessary documents.
