The Social Security Death Index (SSDI) is a widely used collection for modern genealogical research. It is composed of information provided by the Social Security Administration (SSA) for those individuals (with Social Security numbers) who died between 1962* and the present. The SSDI often provides the following information about a deceased individual:
*some earlier dates prior to 1962 can be found
The SSA provides updates to the SSDI on a monthly basis, so it is possible to find more/less information on one database versus another. If you are looking for a recent SSDI entry you may want to search several of the free databases available online:
But Don’t Stop There!! The SSDI can lead to more information about your ancestors!!
First, It may be helpful to know that a Social Security number is made up of series of systematic numbers: the Area, Group, and Serial Numbers:
The Area Number (the first three numbers in the series) refers to a specific geographical region designated by the SSA. Those individuals who applied for their Social Security number from 1935 to 1972 received an Area Number that referred to the local Social Security office in the state in which the card was issued. For those who received their Social Security number after 1972, the Area Number corresponded to the zip code included on their application.**
**It should be noted, however, that a specific Area Number does not necessarily indicate that the individual was living in a particular State at the time of the Social Security application (both before and after 1972). Prior to 1972, individuals could have applied (in-person) for a Social Security number in a neighboring state or their state of employment. Likewise, Area Numbers that were received after 1972 (in hospitals or via mail) were affixed a number corresponding to the zip code indicated on an application. Therefore, if a family moved or had a different mailing address, the Area Number may be different from an individual’s residence at the time of birth.
The Group Number (the middle two numbers in the series) refers to an assigned number, ranging from 01 to 99, within the particular Area Number allocated to a state. The first groups of numbers were issued using odd numbers from 01 through 09 and then even numbers from 10 through 98. After all of the numbers in group 98 of a specific area were issued, the even group 02 through 08 were used, followed by odd groups 11 through 99.
The Serial Number (the final four numbers in the series) refers to the final four assigned numbers, ranging from 0001 through 9999, within each group.
Second, because the SSDI is itself an index, and not the original application, other information can be learned from the Application for a Social Security Number or the SS-5 Form.
The SS-5 application often provides additional information about an individual that was not included on the SSDI record. Additionally, because the personal information included on the application was usually provided by the individuals applying (although in some cases the information may have been provided by the employer), the facts tend to be more accurate. The SS-5 application can provide some of the following information:
To order a copy of a deceased individual’s original SS-5 application, you may do so online at: https://secure.ssa.gov/apps9/eFOIA-FEWeb/internet/main.jsp or via mail at:
Social Security Administration
OEO FOIA Workgroup
300 N. Greene Street
P.O. Box 33022
Baltimore, MD 21290-3022
However, one must be diligent about the newest SSA privacy laws. As of 2011, the SSA will not fulfill a copy request for an SS-5 application for any individual who has a birthdate within the last 120 years. The only exception to this law requires proof of death (using a death certificate, obituary, newspaper article, or tombstone). Therefore, if you are ordering an SS-5 application for a younger individual, you may want to apply in writing. Be sure to include proof of death with the application.
Moreover, this privacy restriction also applies to the names of the deceased’s parents. According to the SSA, “under our current policy, we do not release the parents’ names on an SS-5 application unless the parents are proven deceased, have a birth date more than 120 years ago, or the number holder on the SS-5 is at least 100 years of age.”[1] Therefore, if you are looking for information about the deceased’s parents (which I am sure you are), you must provide proof that the parents are deceased. Again, you will want to apply for the SS-5 application in writing, including proof of death with the application.
