United States Social Security Death Index - FamilySearch Historical Records

Record Description
This Collection will include records from 1875 to 2012.

The index is an online searchable database. It only includes the names of deceased individuals whose deaths were reported to Social Security.

This index is a master index file of deaths reported to the Social Security Administration. It has been kept since 1962, when operations were computerized. The index includes about 50 percent of deceased persons from 1962 to 1971 and about 85 percent of the deceased persons from 1972 to 2005. It also includes a few deaths from 1937 to 1961. As of 2005, the index contained 76 million death records.

The Social Security Administration provides an extract from its file for distribution through the Department of Commerce’s National Technical Information Service. Because this extracted file deals with deceased persons, the information is considered to be public domain. Several organizations have purchased this file and posted it to their Web sites.

This index covers death events from 1962 to June 2011 and a few from 1937 to 1961. Current as of September 30, 2012.

The administration was created in 1936 and began issuing Social Security numbers to track the earnings that workers reported for retirement benefits. In 1961, the Internal Revenue Service began using Social Security numbers to identify taxpayers.

The death date, residence at time of death, Social Security number, and state of issue are usually reliable since it comes directly from the Social Security Administration’s master file. However, realize that errors may have occurred when the information was originally entered. Information listed for the name and birth date was provided by an informant and may be inaccurate.

How to Use the Record
Fill in the requested information in the initial search page. This search will return a list of possible matches.

You may need to compare the information about more than one person to find your ancestor.

Name indexes make it possible to access specific information quickly. Remember that these indexes may contain inaccuracies, such as altered spellings or misinterpretations.

When searching the index it is helpful to know the following:


 * The place where the death occurred
 * The approximate date of the death
 * The name of the deceased

Follow these steps to use the index:


 * Enter your ancestor’s first and last names in the appropriate fields. Be aware that married women are usually listed under their married names.
 * Enter a birth year or death year. For common names enter a year range.

If there are no results, try variant spellings of the names.

Follow the additional instructions on the screen for search tips and to learn how to request a copy of the person’s original application.

Compare the information in the index to what you already know about your ancestor to determine if this is the correct person. You may need to compare the information of more than one person to make this determination.

When you have located your ancestor’s record, carefully evaluate each piece of information given. These pieces of information may give you new biographical details that can lead you to other records about your ancestors. Add this new information to your records of each family.

For example:


 * Use the death date and place to obtain a death certificate. The death certificate may lead you to mortuary, funeral, or church records
 * Use the birth date or age along with the place of birth to find your ancestor’s birth records and parents' names.
 * If your ancestor was born before 1940 you can use the birth date or age along with the place of birth to find the family in census records.
 * Use the residence to locate church and land records.

Keep in mind:


 * The information in the records is usually reliable, but depends upon the reliability of the informant.
 * There is also some variation in the information given from one record to another record.
 * If you are unable to find the ancestors you are looking for, check for variant spellings of the surnames.
 * The index only includes the names of deceased individuals whose deaths were reported to Social Security.
 * Surnames longer than 12 letters are truncated to 12 characters. You may need to retry your search using only the first 12 letters of the name.

You may also want to do the following;


 * Search the index to see if other family members are also listed. These might include the father, the mother, brothers, and sisters.
 * Search the index to see if earlier or later generations are also listed. These might include aunts, uncles, grandparents, or children.

Disclaimer from the National Technical Information Service website, provider of the Social Security Death Index:

"The products advertised on this website contain the complete and official Social Security Administration (SSA) database extract, as well as updates to the full file of persons reported to SSA as being deceased. SSA authorizes the use of this database as a death verification tool, but notes that the Death Master File (DMF) may contain inaccuracies. Thus, SSA cannot guarantee the accuracy of the DMF. Therefore, the absence of a particular person on this file is not proof that the individual is alive. Further, in rare instances it is possible for the records of a person who is not deceased to be included erroneously in the DMF."
