Over a million people are on Obamacare with no Social Security Number.

Multiple independent sources from late June 2026 consistently report that more than one million individuals enrolled in the Affordable Care Act (ACA), commonly known as Obamacare, do not have Social Security numbers on file. This figure has been publicly highlighted by government officials such as Robert F. Kennedy Jr., Secretary of Health and Human Services, and Dr. Mehmet Oz, Administrator of the Centers for Medicare and Medicaid Services. These reports frame the issue as a significant integrity problem, suggesting that some enrollments may involve fraudulent or phantom applicants.

One source referencing earlier data from the Trump administration estimated 2.6 million improper or phantom enrollments remaining in ACA rolls, including over one million without Social Security numbers, indicating this issue has persisted over multiple years. The recent statements emphasize the scale of the problem but do not provide detailed breakdowns of how many of these cases are due to fraud versus administrative or procedural anomalies.

While the core fact about the number of enrollees lacking Social Security numbers is well-supported, the interpretation that all such cases represent fraud or stolen identities is more contentious and less definitively established in the available sources. Some reports use strong language about fraud and call for shutting down these enrollments, but official investigations or audits detailing the exact nature and causes of these missing Social Security numbers are not fully documented in the sources provided.

Therefore, the claim is accurate regarding the number of enrollees without Social Security numbers but should be understood within a broader context where some cases may be due to errors or other factors beyond outright fraud.
