The fastest and cheapest way to find a deceased parent’s Social Security number is to search their personal paperwork, because the number appears on old tax returns, W-2s, bank records, and insurance policies. If those records aren’t available, the Social Security Administration can disclose the number to family members who provide proof of death, and a formal FOIA request will produce it for a fee when nothing else works.
Start With Your Parent’s Own Records
Before you contact any agency, go through the paperwork your parent left behind. Tax documents are the best place to look. Any federal Form 1040, W-2, or 1099 shows the full SSN near the top of the first page.1Internal Revenue Service. Instructions for Form 1040 and 1040-SR – Section: Social Security Number (SSN) A single year’s return is enough. Filing cabinets, desk drawers, storage boxes, and any spot where your parent kept financial papers are worth checking.
Beyond tax returns, the SSN commonly turns up on:
- Bank and investment account opening paperwork, and some older monthly statements.
- Life, health, and auto insurance policies, which frequently list the policyholder’s SSN.
- Pay stubs from employers that used the SSN as an employee number.
- Pension and retirement account statements and enrollment forms.
- Older military discharge papers. DD-214 forms used to print the full SSN; forms issued after early 2025 use a Department of Defense identification number instead.2MyNavy HR. DD Form 214 Updates
Skip the Medicare card. Medicare stopped printing SSNs and switched to a separate Medicare Beneficiary Identifier.3CMS. We’re Using Medicare Beneficiary Identifiers (MBIs) An older card from before the change might still show it, but don’t build a plan around finding one.
Check the Death Certificate
A certified death certificate sometimes includes the full SSN, but this varies by state. Some states print it in full, some redact it, and others leave it off copies available to the general public. States that do include it often limit those copies to immediate family, executors, or people with a legal interest in the estate. If you already have a certified copy, look in the personal information section near the top. If the number is missing or redacted there, ordering another copy from the same state won’t change what’s on it.
If you don’t have a death certificate yet, ordering one from the state vital records office runs roughly $5 to $30. You’ll need at least one certified copy anyway to settle the estate, claim life insurance, or close accounts, so the cost isn’t unique to your SSN search.
Ask Social Security Directly
Most people don’t realize this: SSA policy allows the agency to release a deceased person’s SSN to anyone who provides acceptable proof of death. Privacy protections end at death under both the Freedom of Information Act and the Privacy Act, and SSA’s internal guidelines state that the agency “may disclose any non tax return information from our records about a deceased individual to any party,” including the SSN.4Social Security Administration. POMS GN 03315.010 – Disclosing a Deceased Individual’s Information – Section: Disclosure of Non Tax Return Information
One exception matters. If SSA learned of the death only through state death records shared under Section 205(r) of the Social Security Act, the agency cannot confirm or disclose that information. When proof of death comes from a death certificate, a funeral director’s statement, or a federal source like the VA, disclosure is allowed.4Social Security Administration. POMS GN 03315.010 – Disclosing a Deceased Individual’s Information – Section: Disclosure of Non Tax Return Information
In practice, that means calling SSA at 1-800-772-1213 or walking into a local office with a certified death certificate can produce the SSN at no cost. Results aren’t guaranteed. Some offices will still route you to the formal FOIA process, but the underlying policy is on your side. Bringing a death certificate along with proof of your own identity puts you in the strongest position. If you’re already applying for survivor benefits, the SSA representative handling that claim can look up the SSN as part of the process.
Documents to Have Ready
Whichever route you take, gather the following before you start:
- Your parent’s full legal name, date of birth, date of death, place of death, and parents’ names if you know them.
- A certified death certificate. Required for almost every formal request and strongly recommended even for a walk-in visit to an SSA office.
- Your own valid driver’s license or state-issued ID.
- Proof of relationship, such as your birth certificate showing your parent’s name.
- If you’re the executor or administrator, the certified letters testamentary or letters of administration from the probate court.
Bring originals or copies certified by the issuing agency. Government offices photocopy what they need and return your originals.5Social Security Administration. Form SSA-721 – Statement of Death By Funeral Director – Section: How to Apply for Benefits
The Paid FOIA Route Through SSA
If the free approaches don’t work, you can request a copy of your parent’s original Social Security card application (Form SS-5) or a Numident record through SSA’s FOIA process. Both contain the full SSN. The SS-5 is a photocopy of the paper application your parent filled out; the Numident is a computer extract of the same information. This method works even when you don’t already know the number.
You can file online through SSA’s FOIAXpress Public Access Link at foia.ssa.gov, or print Form SSA-711 and mail it with a check or money order to SSA’s FOIA Workgroup in Baltimore.6Social Security Administration. Make a FOIA Request Paying by credit card also requires Form SSA-714.7Social Security Administration. Can You Provide a Copy of a Deceased Person’s Social Security Number Application for Genealogical Research?
Current fees:
- SS-5 photocopy: $27
- Numident record: $26
- Certification of either record: $10 additional per record
SSA will not process the request without payment.8Social Security Administration. SSA PAL Application – Requests and Fees The Numident is a dollar cheaper and contains the same identifying information, so unless you specifically want the original handwritten application, ask for the Numident.
SSA is required to process standard FOIA requests within 20 working days, though the clock can pause if the agency needs more information from you or has to resolve a fee question. If SSA expects your request to take more than 10 working days, it will send you an acknowledgment.9eCFR. How Does SSA Process FOIA Requests? Plan on roughly four to six weeks from submission to receiving the record by mail.
Why the Social Security Death Index Won’t Help
You may have read that the Social Security Death Index, also called the Death Master File, lists SSNs of deceased individuals. That was true once, and it was freely searchable. Under the Bipartisan Budget Act of 2013, the full Death Master File is now shared only with certain federal and state agencies. The public version, the Limited Access Death Master File, is sold through the National Technical Information Service only to organizations that complete a certification process showing a legitimate fraud prevention or business purpose.10Social Security Administration. Requesting SSA’s Death Information Individual family members cannot access it.
Some genealogy sites, such as FamilySearch, host older SSDI snapshots with records through early 2014. If your parent died before that cutoff, searching those databases is free and worth a try. The records are incomplete, not every entry has an SSN, and nothing has been added in over a decade. Treat it as a long shot.
Protect the Number Once You Have It
Identity thieves target deceased people because the fraud often goes undetected for months. File your parent’s final tax return when it’s due, send a copy of the death certificate to all three credit bureaus to place a deceased alert on the credit report, and watch those reports for unusual activity. If you find that someone has already misused the SSN for tax purposes, you can file Form 14039 (Identity Theft Affidavit) with the IRS on behalf of the deceased.11Internal Revenue Service. Identity Theft Guide for Individuals Shred any documents with the full SSN you no longer need, and keep the rest somewhere secure.
