For many genealogy seekers, the Social Security Death Index is the first step to accurately identifying long lost loved ones and mapping out an accurate portrait of their family ancestry.

The US Social Security Death Index (SSDI) features over 100 million SSDI records dating back to the 1930s. The SSDI is a database of people whose deaths were reported to the Social Security Administration (SSA) beginning about 1962. A small number of deaths in the SSDI files go back before 1962 as early as 1937.

Social Security death records are often a critical step in finding accurate information about one’s ancestors and family members. SSDI can help you find your ancestors’ last known residences, place of birth, death date, confirm accurate ages, get last known contacts. And in some cases, SSDIs can often provide ‘cause of death’ report, which may help reveal or confirm possible examples of hereditary medical conditions that may run in the family.

The free Social Security Death Index is an invaluable resource for many GenealogyBank users, helping make countless searches more efficient, more accurate, and more fruitful.

GenealogyBank updates the SSDI database weekly, including corrections to old death records, as well as new names of the recently deceased. If a person is missing from the index, it may be because the SS death benefit was never requested, the form requesting the benefit had an error, or an error was made when entering the information into the SSDI.
