Voter privacy encompasses two distinct but related protections: the secrecy of the ballot itself, and the privacy of voter registration data. Secret ballot protections, codified in state law in every U.S. state, ensure that no one — including government officials or employers — can determine how an individual voted. Voter registration data privacy governs what personal information states must collect to register voters (name, address, date of birth, and often partial Social Security numbers) and who may access that information.
Federal and state laws create a patchwork of voter data protections. The National Voter Registration Act of 1993 requires states to maintain voter rolls and share certain data with federal agencies for verification. The Help America Vote Act of 2002 required states to match voter registration data against SSA and DMV records. However, neither law was designed to give the executive branch ongoing access to voter registration data for partisan purposes. State-level voter privacy laws vary widely: some states sell voter files commercially, while others restrict access to registered political parties and candidates only.
The tension between election integrity and voter privacy intensifies when federal agencies seek mass access to state voter rolls. When the DOJ''s Civil Rights Division sued 30 states for voter registration data including partial Social Security numbers in 2026, election administrators argued the request went beyond statutory authority and created privacy risks. Critics of the March 2026 mail ballot executive order argued that routing voter eligibility determinations through DHS and SSA databases would expose sensitive citizenship data to political control.
Your voter registration includes your name, address, date of birth, and sometimes your Social Security number. Who can access that data — and for what purpose — determines whether registering to vote creates exposure to government surveillance or political targeting. Voter privacy protections exist because compelled disclosure of voting information has historically been used to suppress turnout.
People often think their vote is entirely private. While ballot choices are secret, voter registration data — including your name, address, and party affiliation — is often public record in many states. What's protected is how you voted; your registration itself may be widely accessible.
