District or Precinct
Voter data files may be requested by a specific jurisdiction (district) or precinct. Depending upon the format requested and your available technology, a countywide voter file may require that it be generated by legislative or commissioner district.
Upon request, voter files can include voting history for all elections (Special, Primary and General) from 2000 - present. Specific elections can also be requested. Each voter's record will include a list of requested elections and an indicator that notes if that particular voter voted in an election.
A matchback file is a list of voters in the current election who have returned a ballot.
Upon request, a matchback file can include only voters who have not yet voted in the current election, or it can include both voted and not voted in the same file.
Your request must specify the dates on which you wish to receive the data.
The same public information as the list of registered voters is available for matchbacks.
To request a statewide voter list, please contact the Secretary of State's Office.
