Until recently, few people had heard of Social Security’s Death Master File (DMF). But since the revelations about Elon Musk’s DOGE plan to weaponize the DMF, the database has become notorious.
How does the Death Master File work?
When someone dies, an “informant” (usually but not always next of kin) give a funeral director personal information about the decedent. That includes the person’s Social Security number (SSN).
The funeral director reports the death to the Social Security Administration (SSA). The SSA then enters the reported date of death in its records, including the DMF.
The SSA shares the full DMF—all information including address—with certain government agencies (e.g. U.S. Treasury, IRS). Certain non-government agencies (banks, credit agencies), once certified, can subscribe to a limited form of the DMF. Both the full and limited DMFs include the decedent’s SSN.
[Please note: you do not need a SSN to be declared dead, buried, cremated, or expatriated.]
What can go wrong with the Death Master File?
Errors
Because the SSA receives around 3 million death reports a year, mistakes happen. Mistakes like typos, data entry errors, or name mix-ups. One consumer legal site notes that “Even a tiny error rate (under 0.3%) means thousands of erroneous death entries. In fact, various audits and estimates suggest that the SSA mistakenly lists roughly 9,000–12,000 Americans dead every year when they are very much alive.
In its surprisingly frank 2019 description of the DMF, the SSA admits “it has been unable to guarantee accuracy in the deaths that it records.” The statement adds “Congress should shift responsibility for collection and dissemination of death data from SSA to Treasury’s DNP (Do Not Pay) portal.” So far that hasn’t happened.
Needless to say, the consequences of being falsely declared dead are devastating. Credit card companies cancel your cards, banks freeze your accounts, and pension plans terminate payments.
No one sends you a letter warning you you’re going to be declared dead next week. Instead you’ll find yourself in a surreal nightmare, your debit card suddenly not working or your retirement account frozen. If the financial system thinks you are dead, you no longer have access to that system.
If this happens to you (and you are still able access the internet or a phone), here’s a resource on what to do.

Sabotage
According to former SSA executive turned whistleblower Jeremiah Schofield, (gift link) Elon Musk’s DOGE people planned to move 2.7 million live people to the DMF. The outrageous plan was intended to promote Trump’s deportation efforts.
DOGE operatives planned to erase lives through a simple database maneuver: entering a false date of death in Social Security records. Thanks in part to Schofield and other conscientious public servants, DOGE’s monstrous plan to “financially murder” 2.7 million people never happened.
But in April 2025, the SSA did put more than 6,000 living persons—mostly Latino immigrants—on the DMF by entering false dates of death for them. SSA, under control of DOGE, just declared them dead.
The origins of the Death Master File
The SSA created the Death Master File in response to a 1980 Freedom of Information Act (FOIA) court-mandated settlement. The court required the SSA to make the surname, Social Security Number (SSN), and date of death of deceased SSN holders available to the public.
From there, the database took on a life of its own. Untrammeled access to Social Security information, not surprisingly, led to criminal activity, especially identity theft. In response, Congress periodically held hearings. Over time, new legislation changed the content and accessibility of the DMF.
How mass fatality events have shaped the Death Master File
The covalent bond between death and politics is nowhere more apparent than in the various Congressional hearings and legislation involving Social Security’s death data collection over the past few decades.
Mass fatality events, in particular, have spurred changes in the administration of the DMF.
The 9-11 attacks
In November 2001, Congress held hearings on identity theft. Some of the 9-11 hijackers had used “phony” SS numbers, and a pilot who’d helped train some of the hijackers had been using the SSN of a dead New Jersey woman for ten years. Rep. Sue W. Kelly (R, NY) blamed Social Security’s slow (“snail mail”) distribution of the Death Master File.
This House hearing led to faster transmittal of DMF information to the financial services industry for the purposes of preventing the crime of identity theft.
Limiting Use of the Death Master File
In 2012, Congress held another hearing on the SSA’s DMF. Their effort to balance privacy with legitimate uses of the database resulted in new legislation.
The COVID-19 pandemic
Remember the March 2020 CARES act? In a desperate effort to save the American economy from tanking as the pandemic took hold, Congress and then-President Trump allocated 2.2 trillion dollars for the Coronavirus Aid, Relief, and Economic Security Act.
In June 2020, the Government Accounting Office (GAO) reviewed how the money was being spent. One finding? “IRS and Treasury made…payments to more than a million deceased individuals.”
Conversely, the GAO also found that some eligible people (e.g. homeless, non-tax-filers) never received payments. Also, about half of the payments to decedents were returned, presumably by honest Americans. Nevertheless, the idea of dollars going to the dead didn’t go over well with Congress.
In December 2020, Congress passed and then-President Trump signed into law the 2.3 trillion dollar Consolidated Appropriations Act of 2021. Tucked into “the longest bill ever passed by Congress” was a provision requiring the SSA to share the full DMF with Treasury’s Do Not Pay working system. This was intended to prevent the deceased (or those using their SSNs) from getting more of the relief funds.
The Death Master File now
Who has access?
Certified (approved) non-governmental users such as banks, credit companies, insurers, and pension plans subscribe to updates of a limited version of the DMF (the limited access DMF or LADMF). It includes first, middle, and last name, Social Security Number, date of death, and date of birth. When someone (or their SSN) shows up in the LADMF, the financial institutions assume the person is dead and may cut off credit or freeze accounts.
Financial institutions don’t get the LADMF directly from the SSA. Instead, Social Security relies on The National Technical Information Service (NTIS) to distribute the subscription file. When certified users enter a username and password on the NTIS website, they can download records in the database. Currently that’s about 85 million records.
Reliability of the Death Master File in question
The SSA has stated that its database is not complete. It does not include every decedent in the United States. There are many reasons for this, including lack of reporting or inability to verify data.
As reports emerged in early 2025 that DOGE was adding living people to the DMF, financial services firms questioned the reliability of the database. As the accuracy of the limited access DMF declined and its integrity became doubtful, some firms began offering auditing and validation of DMF files for clients. “The (limited access) DMF now reflects only 16 percent of actual decedents – a sharp decline over the past 14 years,” claims The Berwyn Group, one of several firms that offers proprietary “death audits.”
Take-Homes for Individuals
When someone dies, the funeral director usually reports the death to the SSA. To deter identity theft and to ensure survivor benefits (if applicable), next of kin should confirm with Social Security that this has been done. Unless you’re able to do this by phone, you may need to make a trip to your local SSA office.
Should you be falsely listed as deceased in the Death Master File, definitely begin with an in-person visit to a SSA office. Again, if this happens to you, here’s a resource on what to do.
