llinois Death Records and Death Index
It may surprise you to learn how often genealogists face this particular set of circumstances. They are aware of when their ancestor was born, when they may have married, when their children were born but they just can’t find out when they died.
There are a fair few instances where the only information missing is the death date which can be very frustrating. This is why knowing what death records may be available to you can be vital in your research.
It is important to note that one of the biggest issues in finding a death record can be looking in the wrong place. You may be surprised how often people miss records because they are looking in the wrong county and sometimes even the wrong state.
In this post we will be looking at Illinois state death records and indexes to try and help you find those elusive ancestors. So if you are confident that your ancestor likely died in the state of Illinois then read on and hopefully we can help you out.
Europeans first arrived in the area we know today as Illinois in 1673 as part of an expedition by Louis Jolliet and Jacques Marquette. During the French and Indian War however the region was ceded to the British.
As a result of the American Revolution Illinois ultimately became part of the United States. It was on December 3rd 1818 that Illinois achieved Statehood becoming the 21st state to do so.
Social Security Death Index 1935 – 2014
All American citizens, naturalized immigrants and resident aliens require a Social Security number for proof of identification and authorization to work. This number follows us throughout our life and when we die this nine digit code is very important.
The Social Security Death Index (SSDI) is a database of death records that was compiled from the United States Social Security Administration Death Master File. This was until 2014 when the rules changed and public access to the Death Master File had to take place through a certification program.
Those researching the deaths of ancestors in Illinois will likely find that most people who have died between 1936 and 2014 can be found on the Social Security Death Index. This does however only hold true if the person had a Social Security number when they died.
It is estimated that since 1973 the SSDI recorded 93% to 96% of the deaths of individuals aged 65 or over. The index was updated frequently and by June of 2011 there were 89,835,920 records available.
The index can be found on websites such as FamilySearch and Ancestry.com and offers details such as:
- Given name and surname (middle initial since the 1990s)
- Date of birth
- Month and year of death (Full date of death for accounts active after 2000)
- Social Security number
- State or territory Social Security number was issued
- Last place of residence when alive including ZIP code

U.S. Social Security Applications and Claims Index, 1936-2007
This is more or less an extension of the information you can find from the Social Security Death Index. It has been extracted from the SSDI records but features more details. It does not include all of the names found in the SSDI however but there are at least 49 million names included.
In this record you may find additional information such as:
- Date and place of birth
- Parents' names who, if deceased, would be over 75 when you are viewing the records (may be redacted if under 75)
- Citizenship status
- Sometimes race or ethnic group

Illinois Death Records Index 1916 – 1950
This index can be located at the Office of Illinois Secretary of State and provides a listing of all the filed death certificates between 1916 – 1950. These are the certificates that would have been filed with the Illinois Department of Public Health during this time frame.
Legislation from 1989 allows the department to make available death certificates that were filed 50 or more years ago although this index only lists up to 1950. This online source is an extension of their Reference Room services. Those seeking more recent death records should contact the Illinois State Archives.
This is only an index of the certificates and as such will not show you digital copies. If you know the full name, birth date and the rough area in which a person died you may be able to locate the death certificate number and order a copy of the record.
