REPORT: In Arizona Tens of Thousands of Duplicative Voter Registrations Found After 2020 Election

Published On: January 31st, 2022

(Alexandria, VA)– January 31, 2022: The Public Interest Legal Foundation (PILF) today released a research brief detailing that Arizona’s voter rolls had tens of thousands of duplicate and potentially unlawful registrations.


  • 31,641 Arizona registrants had second registrations after leaving the state.  
  • 863 Arizonians were registered twice under variations of their names.
  • 499 Arizonans claimed UPS Stores as homes. 110 cast ballots in 2020.

Arizona’s expansion of mail ballots requires increased attention to voter list maintenance. In 2020, Maricopa County led the nation with 110,000 undeliverable ballots.

The state needs to address these issues on their voter rolls before the 2022 elections.

“Arizona election officials still have some time on their side to prepare voter rolls for the midterms – no maintenance scenario is off the table under law,” said PILF President J. Christian Adams. “Recent history has shown how seemingly silly errors in the voter roll can fuel election misinformation and heighten public stress amid a close outcome. PILF looks forward to doing its part in seeing that data findings are swiftly addressed before the 2022 Elections”
