Social Security Death Index (SSDI): Records, Searches, and SS-5 Requests

The Social Security Death Index is a public, searchable version of the Social Security Administration’s Death Master File, listing deaths reported to the SSA going back to the mid-1930s. It’s the tool most people use to confirm a death, pin down a date, or trace an ancestor. You won’t find it on the SSA’s own website; you search it through third-party genealogy platforms, and by federal law, deaths from the past three calendar years are held back from public access.1Office of the Law Revision Counsel. 42 USC 1306c – Restriction on Access to the Death Master File

The SSA itself notes that its records “are not a comprehensive record of all deaths in the country.”2Social Security Administration. Requesting SSA’s Death Information A missing entry doesn’t prove someone is alive; it may just mean the death was never reported to the agency.

What Each Record Contains

A single entry can include the deceased person’s first name, middle name, surname, date of birth, and date of death.2Social Security Administration. Requesting SSA’s Death Information Many records also show the state where the Social Security number was issued and a last known zip code or residence. That last-known-residence field often reflects where the final benefit check was mailed, not necessarily where the person died. Treat it as a clue.

Older archived entries on some genealogy sites still display full nine-digit Social Security numbers, because the SSA distributed them openly in the public file before November 2011. The Bipartisan Budget Act of 2013 then created a separate Limited Access DMF and tightened what leaves the agency.3eCFR. 15 CFR Part 1110 – Certification Program for Access to the Death Master File Newer entries on most platforms redact the SSN or show only a partial number.

Why Recent Deaths Don’t Show Up

Section 203 of the Bipartisan Budget Act of 2013, now codified at 42 U.S.C. § 1306c, tells the Secretary of Commerce not to release Death Master File information about a deceased person during the three calendar years following the date of death, except to certified users like banks and fraud-prevention agencies.1Office of the Law Revision Counsel. 42 USC 1306c – Restriction on Access to the Death Master File

In plain terms: someone who died in March 2024 generally won’t appear on a public search until 2027. If you’re searching for a recent death and coming up empty, this is usually why. Individual family members can’t apply around it; the certification program is designed for institutions handling large volumes of records.4National Technical Information Service.

Where to Search

The SSA does not run a public search page. You go through a genealogy platform that has licensed or archived the data.

FamilySearch (Free)

FamilySearch.org, operated by The Church of Jesus Christ of Latter-day Saints, hosts a free searchable copy. Sign in, click Search, then Records, and type “United States Social Security Death Index” in the collection title search box. The same collection is available through the FamilySearch mobile app. For most people, this is the right first stop because the underlying data is the same as the paid options.

Ancestry (Subscription)

Ancestry.com hosts an SSDI collection covering 1935 through 2014 with over 90 million entries. Access generally requires a paid subscription, though Ancestry sometimes opens specific collections for free. Check whether the SSDI is behind the paywall before you subscribe just for this.

Other Platforms

GenealogyBank and other genealogy sites also offer SSDI searches. The core data comes from the same source, but the date ranges and search interfaces vary, and some platforms archived snapshots before the 2011 and 2013 restrictions took effect. If a search fails on one, try another.

Running an Effective Search

Results depend on what you type in. Before you start, pull together:

  • The full legal name as it would have appeared on government documents. Middle names matter for common surnames.
  • An approximate birth year and death year. If you’re unsure, enter a range instead of guessing a single year.
  • Geographic information — the state where the person lived, worked, or first applied for their Social Security number.
  • Name variations: maiden names, alternate spellings, and likely phonetic errors. Original applications were handwritten and transcribed by clerks decades ago, so misspellings are common.

Too many results? Filter by state or last known zip code. Too few or none? Broaden the name field. Drop the middle name, try a first initial only, or use wildcards if the platform supports them.

When you find a possible match, compare every visible field to what you already know. Confirm birth date, death date, and geography all line up. Picking the wrong person with a similar name is one of the easiest mistakes to make in a database this large.

Why Someone You’re Looking For May Not Appear

Absence from the index isn’t proof of anything on its own. Common reasons for a missing record:

  • The person never had a Social Security number. The SSA has been issuing numbers since 1936, so anyone who died before that system existed, or who never applied, won’t be in the file.2Social Security Administration. Requesting SSA’s Death Information
  • The death was never reported to the SSA. The agency depends on funeral homes, family members, financial institutions, postal authorities, and other government offices to notify it.2Social Security Administration. Requesting SSA’s Death Information
  • The death falls within the three-year restricted window.1Office of the Law Revision Counsel. 42 USC 1306c – Restriction on Access to the Death Master File
  • The death was reported only through a state vital records office. Since November 2011, the SSA has excluded state-reported death records from the public version of the Death Master File.

Coverage gaps grow larger for deaths before the 1960s, when reporting was less systematic. For older research, a missing entry is inconclusive rather than informative.

Getting More Detail: The SS-5 Application

The SSDI entry is a summary. The original application for a Social Security number, Form SS-5, holds information the index does not: the applicant’s parents’ full names, the mother’s maiden name, the place of birth, and sometimes the signature.

You request a copy by filing Form SSA-711 with the Social Security Administration. A photocopy of the original SS-5 is $27. A computer-generated extract, which may not include parental names or birthplace, is $26. A certified copy costs an additional $10.5Social Security Administration. Request for Deceased Individual’s Social Security Record (Form SSA-711) Pay by credit card using Form SSA-714, or by check or money order. The SSA does not accept cash.

Mail the completed form to SSA OEIO DEBS FOIA, PO Box 33022, Baltimore, MD 21290-3022, or send it by express mail to 6100 Wabash Ave., Baltimore, MD 21215. Processing runs four to six weeks.5Social Security Administration. Request for Deceased Individual’s Social Security Record (Form SSA-711) Two limits worth knowing: the SSA can’t process requests for people who died before November 1936 or who were born before 1865 unless you supply the Social Security number. And if the person died within the past 100 years, you’ll need to include proof of death, such as an obituary or death record, or the SSA will redact the parents’ names.

If You’ve Been Listed as Deceased by Mistake

Occasionally a living person turns up in the SSA’s death records by error. The agency reports that fewer than one-third of one percent of the death reports it receives are wrong, but with millions processed each year the affected population is real.6Social Security Administration. Social Security Provides Update About Its Death Record Benefits stop, bank accounts freeze, insurance claims stall, and credit applications get denied.

If it happens to you, go to your local Social Security office in person as soon as you can. Bring an original proof of identity such as a passport, driver’s license, or military ID. The SSA won’t accept photocopies, notarized copies, or receipts. Documents must be originals or copies certified by the issuing agency.7Social Security Administration. What Should I Do If I Am Incorrectly Listed as Deceased in Social Security’s Records?

Once the record is corrected, the SSA will issue a letter titled “Erroneous Death Case – Third Party Contact” that you can hand to your bank, insurance carrier, doctors’ offices, and anyone else still treating you as deceased. Keep copies. Untangling the downstream effects across different institutions often takes months.
