Social Security Administration announces its 'most comprehensive' records cleanup ever. Here's what it means.

The U.S. Social Security Administration (SSA) said Tuesday that it has corrected millions of records associated with nearly 15% of active Social Security numbers (SSN), which it said was part of an effort to prevent fraud.

The agency called it the "most comprehensive SSN record clean-up" in its 91-year history, and said it had added 17 million missing dates of death to its records and updated citizenship information for about 25 million records.

It is also working to correct another 8.5 million records with inaccurate citizenship status and has introduced stronger internal controls to prevent future data-entry errors.

"This is the first time SSA has undertaken an effort of this scale, and I am proud of the work we have done to strengthen the foundation of identity data relied upon throughout government and the economy," Commissioner Frank J. Bisignano said in a statement outlining the work the agency had carried out.

The SSA said the changes are intended to improve the accuracy of records used by federal and state agencies to verify identities, prevent fraud and ensure government benefits are paid correctly.

Here's what we know about the cleanup so far — and what it could mean for your account.

The SSA cleanup focuses on the Social Security number (SSN) database, which government agencies use to verify identities and help administer benefits.

According to the SSA , millions of records were missing a date of death or citizenship information.

To address those gaps, the agency used information from its own systems and the State Department to add missing dates of death. It also used data from the Department of Homeland Security to update citizenship records.

The SSA said the corrections are intended to improve the accuracy of its records, prevent fraud and reduce improper payments across government programs.

The agency has also introduced stronger internal controls designed to prevent future errors caused by manual data entry.

Could the cleanup affect your benefits or records?

Accurate death and citizenship records help determine who is eligible for Social Security benefits and prevent incorrect payments.

Death records are particularly important for survivor benefits, which provide financial support to eligible family members after someone receiving or eligible for Social Security dies.

However, the SSA has not said whether its latest corrections have changed anyone's benefit payments or eligibility, or whether anyone has had problems with their records.

The accuracy of death records has drawn scrutiny before.

Earlier this year, a former senior SSA 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 the plan was rejected but alleged that more than 6,000 people were incorrectly recorded as dead in a separate April 2025 update. The SSA has denied adding the proposed 2.7 million names to its Death Master File.

The SSA has not announced any new requirements for people to check or update their Social Security information after the cleanup.

However, people can review some of their information through their online my Social Security account , including their earnings history and, for those receiving benefits, payment details.

Anyone who notices an error in their records or experiences an unexpected interruption to their benefits can contact Social Security directly to ask about the issue and how to resolve it.

The agency has not said that the latest cleanup requires beneficiaries to submit new documents or take any other action.
