A U.S. Social Security Administration update added death and citizenship details to millions of records used by federal and state agencies for identity checks and efforts to prevent improper payments.
In an Oct. 20 announcement, SSA said it added death dates to 17 million records where the information was absent. It also entered citizenship information missing from about 25 million records. Another 8.5 million records with inaccurate citizenship status remain under review and correction.
SSA described the effort as its largest review of Social Security number records in 91 years. It reported that nearly 15% of active Social Security numbers had been corrected since the start of the Trump administration, but did not give an exact total of distinct records.
Death information came from SSA systems and data supplied by the U.S. Department of State. For citizenship updates, SSA drew on the Department of Homeland Security’s Systematic Alien Verification for Entitlements (SAVE) service. SAVE gives authorized agencies immigration or citizenship verification information; it does not decide benefit eligibility.
SSA Commissioner Frank J. Bisignano said, “Accurate SSN records prevent fraud across federal programs.” The agency also said it has strengthened controls to reduce errors from manual data entry.
A missing date alone does not show that someone received benefits improperly. Former acting SSA Commissioner Lee Dudek said in February 2025 that people without death dates in agency records were “not necessarily receiving benefits.”
Treasury separately uses SSA’s Full Death Master File in payment screening. On Oct. 6, it said its fiscal 2026 screening had returned about 13,500 payments worth $175 million after identifying them as intended for deceased people. That announcement came before the SSA update, and Treasury did not attribute the results to this cleanup.
Separately, SSA reported that it later determined 12,504 of approximately 5.6 million death records posted in 2025 were erroneous, according to an Office of the Inspector General release.
