Questions about voter registration systems and citizenship checks have drawn national attention as states face renewed scrutiny over election administration. In New Jersey, that debate narrowed sharply on July 21, 2026, when Gov. Mikie Sherrill said a software error in the Motor Vehicle Commission system had improperly added thousands of people to the voter rolls after they indicated they were not U.S. citizens. State officials have said the registrations occurred before Sherrill took office and are now under review.
New Jersey identified a software error and put a number on it
Gov. Mikie Sherrill said on July 21 that a software error in New Jersey’s Motor Vehicle Commission system registered roughly 6,600 people to vote between June 2023 and June 2024 after they indicated they were not U.S. citizens, according to the governor’s office. The administration said the error was discovered years after the affected transactions took place and that the registrations occurred under the prior administration.
The governor said she immediately ordered an investigation by her counsel and directed state officials to remove from the voter rolls residents who were added in error during that period. A state question-and-answer page later said the problem stemmed from a vendor’s software tied to MVC transactions, not from a change in voter eligibility law. The administration also said the new MVC administrator had begun replacing the vendor responsible for administering the system.
By Aug. 19, the governor’s office said about 5,100 registered individuals had been placed in deleted status because they were registered only because of the system error and had no other registration or attestation to voter eligibility in the system. Officials also said additional cases were still being reviewed to determine whether people had later completed other transactions that included voter eligibility questions. The state has framed the review as both a voter-roll correction effort and an eligibility-protection process for lawful voters.
What is confirmed is that the registrations involved New Jersey Motor Vehicle Commission transactions completed between June 2023 and June 2024 and that the affected population includes people who indicated they were not U.S. citizens, according to the governor’s office and the state’s MVC error page. New Jersey has also confirmed that it began notifying people believed to be affected and created a public information page explaining how people can check their status and request removal if they were mistakenly registered.
What is not publicly known is a county-by-county breakdown of every affected registration or a complete public list of all local jurisdictions touched by the error. The state has not released a comprehensive municipality-level accounting, and officials have said some records require individual review because later transactions may have included additional voter-related attestations. That means the final number removed from the rolls may not match the initial number flagged by the system review.
The issue is significant in New Jersey because voter registration can be linked to MVC records, and the state’s Division of Elections uses those records to validate identification and retrieve digitized signatures during registration processes. State law still requires that a voter be a U.S. citizen, at least 18 years old, and otherwise qualified to vote. The state has also emphasized that people who were registered in error can contact election officials to have their names removed.
State officials have attributed the problem to a vendor software error inside the MVC system, not to a legislative change permitting non-citizens to vote in statewide elections. Sherrill said the administration moved to replace the vendor after learning of the issue, and the state’s public guidance describes the registrations as the result of a system defect discovered after the fact. Those statements place the cause in election-adjacent administrative technology rather than in New Jersey’s voter qualification rules.
The broader context is that citizenship verification and voter registration procedures have become a national political flashpoint, even as documented cases of non-citizen voting remain rare compared with the overall number of ballots cast, according to the Associated Press. That national backdrop helped elevate the New Jersey disclosure beyond a routine database correction, particularly because the affected population was large enough to trigger a statewide review and public messaging campaign.
For New Jersey residents, the practical takeaway is that election officials are continuing to review records, remove registrations tied only to the error, and preserve the rights of eligible voters whose records may require closer examination. The state has said people affected by the MVC error are being notified and that individuals who believe they were mistakenly registered can seek removal through election officials. As of the latest update from the governor’s office, the review and cleanup process was still ongoing ahead of New Jersey’s 2026 general election cycle.
