The Social Security Death Index is an interactive search engine sponsored by RootsWeb. It lists the name, birth date, death date, social security number and state of SSN issue for individuals who applied for social security in the United States and who have since died. It may list the last residence of the individual. It also includes links to a form letter to request a copy of the individual's social security application, a "Post It" feature used to leave notes about the individual and an Ancestry.com search feature. These records are updated once a month with updates from the US Social Security Department.
