Anyone who registers to vote as a resident of a particular state is listed on voter data information found online. The general public is not given access to voter registration information and cannot find out who is listed on voter rolls. However, voter registration data is sold to election candidates, political campaigns and certain organizations. Voter registration lists are considered public records and are government documents managed by local voter agencies tasked with collecting registrations and managing voter lists.
Due to public records laws, voter registration information is made available on a limited basis to parties who can prove they are entitled to have valid access to this data. Data such as name, address, birth date and party affiliation is commonly distributed electronically. States such as Florida have privacy protections in place that prohibit the distribution of some voter registration information. Florida prohibits the release of Social Security and driver's license numbers, but voters can achieve additional privacy by participating in the state's Address Confidentiality Program run by the Florida Attorney General. Florida voters in high-risk professions can send written requests asking agencies not to reveal private information.
Companies such as Voterlistsonline.com sell voter registration data to third parties, but that company requires its customers to go through identity verification. This company doesn't provide online search access to individual names and addresses.
