Voter ID Laws

A total of 35 states have laws requesting or requiring voters to show some form of identification at the polls. Scroll over the map below for state-by-state details.

Notes: On March 18, 2022, Act 249, which passed in 2021 and made changes to Arkansas's voter ID law, was deemed unconstitutional. On April 6, 2022, Montana SB 169, enacted in 2021, was deemed unconstitutional. Appeals in both cases are likely.

The remaining 15 states and D.C. use other methods to verify the identity of voters. Most frequently, other identifying information provided at the polling place, such as a signature, is checked against information on file. See NCSL’s Voter Verification Without ID Documents.
