Using Social Security Death Index (SSDI) in Your Reseach

ancestryseekingWhat is  the Social Security Death Index (SSDI)?

The Social Security Death Index (SSDI) is a database of people whose deaths were reported to the Social Security Administration (SSA) and are listed in the SSD Master File.

What Information will I find in a SSDI?

SSDI will usually show you when the person first applied for their social security card. Their date of birth and death and where their last residence.

In March 2014, Social Security information became restricted and new entries  into the Social Security Death Index are now not available for three years beginning on the  individual’s date of death.

Social Security  payments first started around 1940, so you will not find any information about a person before then. The SSDI list  has very few entries for people who died from 1940-1961. You may find state listings for death indexes before 1962.  Only those who had a social security card would be listed.
