Voter List Maintenance & Registration Cancellation

Voter list maintenance is a crucial function of the Maricopa County Recorder's Office, ensuring the accuracy and integrity of the county's voter rolls. Registered voters in Maricopa County have the option to update or cancel their voter registration when they move or no longer wish to be registered to vote.

Voter Registration Cancellation

The Maricopa County Recorder’s Office is required by federal and state laws to maintain accurate and up-to-date voter registration lists to ensure election integrity. 

This involves regularly removing ineligible voters, such as those who have moved or passed away, while also adding newly registered voters. Accurate voter rolls help prevent potential fraud, ensure ballots are sent to correct addresses, and maintain public confidence in the electoral process.
