How to Apply for Voter Registration Data

California Election Code requires an application to receive voter registration information which can only be used for elections, scholarly, or governmental purposes.

What Information is Available in a Voter File?

Voter registration information is available to any candidate for federal, state, or local office, to any committee for or against any initiative or referendum measure for which legal publication is made, and to any person for election, scholarly, journalistic, or political purposes, or for governmental purposes, as determined by the Secretary of State. To receive this voter information, you must fill out a Voter Information Data Request Form with a copy of your driver's license or state-issued identification card and pay the associated fees for voter files. A voter file may contain some or all of the following information:

  • First name / last name
  • Birthdate and birthplace
  • Permanent Vote by Mail voter status
  • Date last voted
  • Residence and mailing address
  • Political Party
  • Precinct number /group
  • Date of registration
  • Voting history for countywide elections from the last 5 statewide elections
  • Email address (if provided by the voter)
  • Telephone number (if provided by the voter)

Election-specific Vote-by-Mail Data

California Elections Code requires county election officials to mail a ballot to all active registered voters eligible to vote in each election. The status of each voter's vote-by-mail ballot is tracked by the Yolo County Elections Office and is available to purchase for the specific uses described above - political, election, journalistic, scholarly, and governmental. The information is confidential and cannot be used for commercial purposes. A requestor must use the Voter Information Data Request Form to receive vote-by-mail data about specific voters.

Non-Confidential Data (Maps and Reports)

Some data sets available at the Yolo County Elections Office are not confidential and are available to the public. Most of that data is available on our website but you must contact us for maps, shapefiles, precinct-district relationship files, home precinct-to-consolidated precinct reports, and other dynamic, non-confidential files.  If you wish to receive such public data, please complete the Non-Confidential Data Request Form. A copy of your driver's license or state-issued identification card is not required; however, applicable fees must be paid when submitting the request.
