Millions of voter registration submissions have failed to match federal records through the Social Security Administration's HAVV system, raising questions about election verification processes. Federal data reveals that since 2011, 28.8% of checks—approximately 28.1 million submissions—returned a "No Match" result. The HAVV system serves as a last-resort verification for individuals registering to vote without a driver's license, relying on their name, date of birth, and the last four digits of their Social Security number.
Established under the 2002 Help America Vote Act (HAVA), the system provides one of four responses from the SSA: deceased, alive, matching records, or "No Match Found." A "No Match" indicates that the provided information does not align with SSA records. In 2025 alone, 13% of submissions, totaling 318,217 out of 2.37 million, failed to match, highlighting ongoing discrepancies in the verification process.
A notable spike occurred in Arizona in 2021, coinciding with a forensic audit of the 2020 election in Maricopa County. Weekly HAVV transactions surged from 500 to 70,000, and 58% of 673,000 submissions resulted in "No Match" responses. Maricopa County officials, who opposed the audit, submitted hundreds of thousands of verification requests during this period.
Seven states—Kentucky, New Mexico, Oklahoma, North Dakota, South Carolina, Tennessee, and Virginia—have opted out entirely of the federal HAVV system, relying instead on their own verification methods. Additionally, in 2025, four states processed not a single applicant through the system, creating variations in how voter eligibility is confirmed nationwide.
Efforts by the Department of Justice to examine state voter rolls have faced blocks from judges in Michigan, Oregon, and California. These developments come amid calls for stronger safeguards, including the SAVE Act, which would mandate proof of citizenship and photo ID for voter registration to address unverified submissions.
The accumulation of 28.1 million "No Match" results over 15 years underscores persistent challenges in voter roll accuracy, with federal data pointing to a system strained by high volumes of unconfirmed registrations.
