Last updated · Written for someone holding an SSA notice and a stack of paper. We are not affiliated with the Social Security Administration and this page is not legal or benefits advice.
The Social Security Administration does not publish one national fax number. Faxing goes to the specific office handling your case — a field office, a state disability determination services (DDS) office, or a processing centre — and each has its own local number. Take it from the notice SSA sent you, or find the office in SSA’s Office Locator and call to ask. Any site quoting a single “SSA fax number” is guessing.
Does SSA actually accept documents by fax?
Yes, and we can show it from SSA’s own staff manual rather than from hearsay. The Program Operations Manual System (POMS) is the agency’s published internal policy, and it says several useful things:
- When a disability determination services office receives medical records by email, the examiner must tell the sender that email is not secure and “advise the sender to mail or fax copies of the records, or use the ERE website” (DI 81020.060). Fax is one of the three routes SSA itself names.
- SSA staff fax paper into the Certified Electronic Folder using barcode cover sheets that index each document to the right case and the right section of the file (DI 81010.090).
- Field offices may fax medical evidence of 15 pages or less straight into the electronic folder for expedited case types — terminal illness, presumptive disability, quick disability determination, compassionate allowance — and must verify afterwards that every page is legible(DI 81010.125).
What none of that gives you is a number to dial. The barcoded fax routes are internal, and the public-facing fax numbers are office by office.
How do I find the right SSA fax number?
In this order:
- The notice in your hand. SSA letters name the office handling the matter and frequently print a direct fax number for returning the enclosed forms. That number beats anything you will find by searching.
- SSA’s Office Locator. Enter your ZIP code at
ssa.gov/locatorto get the field office that serves you, with its address and phone number. - Call and ask. Ask for the fax number for the specific document — offices sometimes use different numbers for claims paperwork and for medical evidence, and a receptionist will tell you which.
We deliberately do not list SSA field office fax numbers on this page. They are per-office rather than published centrally, they change, and a wrong fax number is worse than no fax number: your documents go somewhere, and you believe they arrived.
Fax, online account, mail or Electronic Records Express?
Being honest about this is the point of the page. For several SSA tasks the online route is genuinely better, and we would rather you finish the errand than buy a fax.
| Channel | Best for | Watch out for |
|---|---|---|
| Your my Social Security account | Tasks that have an online form. A continuing disability review can often be filed as the i454 report instead of posting back the paper SSA-454 (POMS DI 13005.037). | Only available for some cases — adults without a representative payee, and only when SSA has opened the review. |
| Electronic Records Express (ERE) | Medical providers and appointed representatives sending evidence into an existing case folder. | Not a general public upload portal; it needs the case identifiers and the correct indexing. |
| Fax | Returning forms and evidence to a named office against a deadline, and sending from outside the US where mail takes weeks. | You must have the right office’s number, and the pages must be legible after scanning. |
| Originals, very large packets, and anything SSA enclosed a return envelope for. | Transit time, and no proof of arrival unless you pay for tracking. | |
| Nothing. SSA’s manual instructs staff to tell senders that email is not secure. | Do not send medical records or a Social Security number by email. |
What do people actually fax to Social Security?
From SSA’s own forms list for these processes, the recurring items are:
- SSA-454-BK, the Continuing Disability Review Report — the long form SSA sends when it reviews whether a disability still qualifies. We have a page on faxing that one.
- SSA-455, the Disability Update Report — the short mailer version of the same review (POMS DI 28001.003).
- SSA-827, Authorization to Disclose Information to the Social Security Administration. It travels with almost everything medical.
- SSA-3368-BK, the Disability Report — Adult, and the work activity reports SSA-820 and SSA-821, which SSA lists as supporting documents in a review package (POMS DI 13005.037).
- Medical evidence — clinic notes, imaging reports, hospital summaries. See faxing disability claim documents for what SSA says should and should not go by fax.
We are not going to tell you which of these applies to you, what to write on them, or what SSA will decide. That is between you, SSA and, if you have one, your representative. What we can do is get the pages there and give you a receipt.
How to fax documents to an SSA office, step by step
- Find the office that actually has your case. Read the notice SSA sent you. It names the office handling the matter, and often prints its direct fax number. If you have no notice, use SSA's Office Locator at ssa.gov/locator to find the field office for your ZIP code, then call it and ask for the fax number for the document you are sending.
- Check whether there is an online route first. Some tasks have one and it is faster. An adult beneficiary without a representative payee can often complete a continuing disability review online as the i454 report inside a my Social Security account instead of returning the paper SSA-454. If an online channel exists for your form, use it and skip the fax.
- Assemble the pages in the order SSA asked for. Put the signed form first, then the authorisation (usually the SSA-827), then the supporting evidence grouped by source. Do not interleave sources. Number the pages by hand if the originals are not numbered, so a missing page is obvious to whoever indexes them.
- Make the pages legible before you send. Incoming paper is scanned or faxed into an electronic case folder and SSA staff are instructed to verify that every page is legible. Scan or photograph in good light, straighten the page, and prefer grayscale over heavy black-and-white thresholding, which can erase faint handwriting and pale lab print.
- Add a cover sheet with the identifiers. Claimant name, the Social Security number or last four digits if the office asked for it, the form or claim the pages belong to, the office and department, your callback number, and the total page count including the cover sheet.
- Send it, then keep the transmission result. Upload the file to an online fax service, enter the office's fax number, and send. When the call finishes you get a result showing the number dialled, the page count and the time. Keep it — that record, not the fax itself, is what proves a specific document reached a specific number on a specific day.
Why the number you send from matters
This is the part most people discover late. A fax reply goes back to the number the original fax came from — there is no “reply-to” field to override. If an office is going to fax you something back, or if you want your number on the correspondence trail, you need your own fax number, not a shared sending number that hundreds of other people also send from. The clearest example is business-side paperwork: agencies that return a document by fax return it to the sending line. It applies to SSA correspondence too.
If you genuinely only need to push one packet out and never hear back by fax, you do not need a subscription at all — Pay Per Fax is $2.99 for up to 10 pages. If a reply might come, start with a number of your own. See how receiving works, or why there is no such thing as a permanently free fax number.
