Notes: The Social Security Administration Death Master File contains information on millions of deceased individuals with United States social security numbers whose deaths were reported to the Social Security Administration. Birth years for the individuals listed range from 1875 to last year. Information in these records includes name, birth date, death date, and last known residence. The Social Security Administration has a microfilmed copy of every individual's original Social Security application (known as the SS-5), as well as claims files. These documents contain additional information not available in the index such as birthplace, maiden name, and parents' names and can be requested for a fee for the SSA.
