Social Security Administration Death Master File

Does SSA make its Death Master File available online for the purposes of genealogical research? -- "Although the Death Master File is not available online from SSA, the United States Department of Commerce's National Technical Information Service (NTIS) offers a subscription service for online queries of the Death Master File through their website....Please note that other parties have purchased SSA's Death Master File Extract through NTIS and then posted it on their own websites. Although these private parties call/refer to their own websites as SSA's "death index" or SSA's Death Master File, these are not endorsed by SSA, nor can SSA confirm that these private websites are kept up-to-date or accurate with SSA's death data in any way."

RootsWeb's Guide to Tracing Family Trees: Social Security Death Index provides guidance on research using social security numbers.
