Voter files are digital databases of information about registered voters that the federal government requires each state to maintain. States can legally sell voter file information to individuals or groups, and each state has developed its own guidelines regarding these sales. Prices range from $0 to $37,000. Additionally, the data included for sale and the individuals and groups allowed to purchase voter files varies from state to state.
In a 2016 report, the U.S. Election Assistance Commission classified the availability of voter file information in each state as either open, mixed, or restricted, based on the type of individuals or group that were allowed to purchase the data.
As of August 2022, voter file data is available for purchase in every U.S. state and Washington, D.C. Thirty-one states have open availability, meaning they have no restrictions on the types of individuals and groups that can purchase their voter file data. Sixteen states have mixed availability, meaning certain types of individuals or groups can purchase information from voter file data that is unavailable to others. Four states have restricted availability, meaning only certain types of individuals or groups are allowed to purchase their voter file data.
