How to Fax to Social Security: SSA Fax Numbers and a Step-by-Step Guide
The Social Security Administration asked you to fax something. Maybe it's a disability claim, a name change form, or proof of identity. Here's exactly how to get your documents to the right SSA fax number without hunting down a fax machine.
Does Social Security Accept Faxes?
Yes, for many supporting documents and post-filing forms. Social Security field offices, hearing offices, and national processing units still accept faxed releases, representative forms, appeal paperwork, and medical evidence.
The catch: there's no single fax number for all of Social Security. Each local field office, hearing office, and processing center has its own fax number. The number you need depends on what you're sending and which office is handling your case.
Initial applications are the exception. If you are starting a brand-new claim, file it online, by phone, or with the office handling your case unless the instructions specifically tell you to fax something.
If an SSA representative gave you a fax number on a letter or during a phone call, use that number. It's the most reliable way to make sure your documents reach the right person.
How to Find Your Local SSA Fax Number
Social Security does publish some fax numbers on SSA.gov, but not as one neat, nationwide directory. The safest way to find the right destination is to start with the office already handling your case:
Check your correspondence. Any letter from the SSA about your case should include a fax number for the office handling it. Look at the letterhead or the contact section at the bottom. This is your best source.
Call the SSA directly. The main number is 1-800-772-1213 (TTY: 1-800-325-0778). Ask for the fax number of the specific office handling your claim. Representatives can look it up and give it to you on the spot.
Visit the office locator. Go to ssa.gov/locator to find your nearest field office. Many office results include the local fax, and if the result does not show it, the office phone number on that page can confirm the correct line before you send.
Check hearing and appeal notices. If your claim is already at the hearing or Appeals Council stage, the fax number is usually printed on the notice itself. Hearing offices commonly use toll-free 833 fax lines that are assigned to a specific case queue or office.

SSA does not publish one master claimant fax directory, but it does publish a mix of office-specific fax numbers, toll-free hearing routes, and national processing fax lines. The table below combines the official public numbers and lookup methods that are most useful in practice.
| Office Type | Fax Number or Route | Best Used For |
|---|---|---|
| Local field offices | ||
| Your local SSA office | Use ssa.gov/locator | General case paperwork, identity documents, and office-specific requests |
| Whittier, California field office | 1-833-950-2458 | Example of a publicly listed local office fax on an SSA regional office page |
| San Bernardino, California field office | 1-909-383-5860 | Another public local office fax published by SSA |
| San Francisco, California office | 1-510-637-4027 | Published public fax for a metro office, useful as a current-format example |
| Hearing offices and appeals | ||

| Appeals Council, HA-520 request for review | 1-833-509-0817 | Requests for review and supporting records for the Appeals Council |
| FECS, Falls Church and Crystal City branches | 1-877-310-0025 | Electronic folder and appointed representative routing for hearing-level work |

| Processing center fee payment issues | 1-877-385-0643 | Paperless Processing Center route for representative fee payment problems |

| Business entity tax information for appointed reps | 1-833-597-1429 | Form SSA-1694 and related representative tax paperwork |
Important: Verify the number before sending. SSA publishes some office fax numbers on current office pages and some in form instructions or reference manuals, so the safest rule is still to match the fax line to the exact office, branch, or form named in your notice.
What Documents Can You Fax to Social Security?
Fax is best for the supporting forms and evidence SSA still routes through local offices, Disability Determination Services, hearing offices, and specialty units. These are the documents people most often send by fax:
SSA-827
The SSA-827 is the authorization that lets Social Security and disability examiners request medical records. It is commonly faxed with disability claims, reconsiderations, and hearing-level evidence packets.
SSA-1696
The SSA-1696 appoints a representative. SSA instructions for the paper form say it can be mailed, faxed, or delivered to your local Social Security office.
Appeal forms
Appeal paperwork such as reconsideration requests, HA-501 hearing requests, HA-520 Appeals Council requests for review, and supporting briefs are often faxed to the office named on the notice.
Disability determination forms and evidence
Work history reports, function reports, treatment notes, imaging, lab results, and other medical evidence are routinely faxed to DDS or the hearing office handling the file.
If the instructions do not say fax is allowed, call first. That matters most for brand-new applications and replacement-card requests, where SSA may want you to file online or present the documents another way.

Tips for Faxing the SSA Successfully
Include your claim or case number on every page. SSA offices process thousands of faxes daily. Without a claim number, your documents could sit in a pile with no way to match them to your file.
Fax during business hours when possible. SSA fax machines are more reliable Monday through Friday, 8 AM to 5 PM local time. Unlike the IRS, SSA offices are smaller and their fax lines can fill up quickly.
Follow up by phone. After sending your fax, call the office in 2 to 3 business days to confirm they received it. Fax confirmations prove you sent it, but a quick call confirms it made it into your file.
Keep copies of everything. Save the original documents, your fax confirmation, and a note of the date and fax number you used. If anything gets lost, you can resend immediately.
