The Social Security Death Index (SSDI) is a searchable database created from the U.S. Social Security Administration’s Death Master File, which contains the name and social security number of deceased persons reported to the Social Security Administration since roughly 1962. In addition to being used by genealogists, the Death Master File and SSDI are used by financial firms and government agencies for various reasons such as preventing identity fraud.
