The Trump administration has corrected tens of millions of Social Security number records in what the Social Security Administration calls the most comprehensive cleanup of the database in its 91-year history, adding 17 million missing dates of death and filling in citizenship information on about 25 million others.

The agency, which tied the work to a government-wide effort to prevent fraud, disclosed the figures in a release on Tuesday. In all, it said, it has corrected nearly 15 percent of active Social Security numbers since the start of the Trump administration in January 2025, a total Fox Business put at nearly 50 million records. The database spans about 330 million U.S. citizens and nearly 390 million records in all. The death dates came from the agency's own systems combined with State Department data, while the citizenship updates drew on data from the Department of Homeland Security's Systematic Alien Verification for Entitlements service, known as SAVE. The work is not finished. About 8.5 million records with inaccurate citizenship status are still being corrected, and the agency said it has added stronger internal controls to keep manual data entry from introducing new errors.

Commissioner Frank Bisignano called the database "our country's books and records" in the release. "The database's accuracy is essential to maintaining integrity of government services for citizens," he said. "Accurate SSN records prevent fraud across federal programs and support the proper administration of benefits." He said the agency had never attempted an effort of this scale and that the work strengthened "the foundation of identity data relied upon throughout government and the economy."

That reach is why a missing entry matters. Federal agencies and states use Social Security records to verify identities and to prevent improper payments of taxpayer money, so an error such as an absent death date can carry consequences well beyond Social Security itself. Earlier this year, the Treasury Department reported that by checking payments against the agency's Full Death Master File, it stopped roughly $99 million that had been set to go to dead people. Treasury said it would keep using that screen across federal programs before money leaves government accounts.

The cleanup is one piece of a broader administration drive against benefit fraud. Trump created a Task Force to Eliminate Fraud by executive order in March, naming Vice President JD Vance as its chairman and charging it with coordinating a national strategy to stop fraud, waste and abuse in federal benefit programs.

Newsweek reported that the announcement will not change monthly benefits for ordinary recipients, and the agency does not reassign a Social Security number after its holder dies, the New York Post noted. The agency has not said whether the corrections have changed any individual's payments or eligibility, Yahoo News reported.

Death records have drawn scrutiny before. Earlier this year, a former senior agency official alleged in a whistleblower disclosure that Homeland Security officials, with involvement from Department of Government Efficiency staff, pushed the agency to mark as many as 2.7 million people as dead without sufficient evidence. The former official said that plan was rejected but alleged that more than 6,000 people were incorrectly recorded as dead in a separate April 2025 update. The agency has denied adding the proposed 2.7 million names to its Death Master File.

Outside analysts cautioned against reading the size of the cleanup as a measure of fraud. Alex Beene, a financial literacy instructor at the University of Tennessee at Martin, told Newsweek that "millions of inaccurate records don't necessarily equate to millions of fraudulent payments, and there is currently no evidence that fraud occurs on anything approaching that scale." He called the changes positive for beneficiaries but said the government "must also ensure these changes don't mistakenly interrupt legitimate benefits."

Kevin Thompson, chief executive of 9i Capital Group, said he did not believe fraud connected to missing death records was "particularly common," because most deaths are reported through funeral homes and documented by states through death certificates. He still saw a benefit: updated records, he said, make it easier to identify numbers that belonged to people who have died, "potentially reducing opportunities for identity theft and fraudulent benefit payments." Thompson suggested the gaps went unaddressed for years because fixing them is clerical, time-consuming work, and that newer technology appears to have made the job efficient enough to justify the expense.

Improper payments, a broader category than fraud, are a long-running concern for the program. A 2024 report from the agency's inspector general found that of nearly $8.6 trillion in benefits paid from fiscal 2015 through 2022, about $71.8 billion, or 0.84 percent, was paid improperly, mostly in overpayments. Such payments often stem from beneficiaries not reporting required information or from records that are not updated on time. In September, the inspector general estimated that about $1 billion had been improperly paid to 333,800 Supplemental Security Income recipients whose earnings had not been properly reviewed or recorded.
