How to fax documents to your Social Security office
Social Security still asks for a lot of paperwork by fax — pay stubs, award letters, forms for a disability claim. The catch: there's no national SSA fax number. Every field office has its own, and your fax needs to land at the office handling your case.
Finding the right fax number
In order of reliability:
- Check the letter SSA sent you If Social Security requested documents, the letter almost always prints the exact fax number (and sometimes a barcode cover sheet) for your case. Use that number — it routes into your file.
- Use the SSA office locator Enter your ZIP code at ssa.gov/locator to find the field office that serves your address, with its contact details. Local office fax numbers typically start with 833 or 844.
- Call and ask Call the office directly, or SSA's national line at 1-800-772-1213, and ask for the fax number to use for your specific matter — disability paperwork sometimes goes to a state DDS office rather than the field office.
What to put on the fax
- Cover page: your full name, phone number, the last four of your SSN or your claim number (use whatever identifier your SSA letter shows), what you're sending, and the page count.
- Every page: write your claim number or name in a corner, so pages that get separated still reach your file.
- Copies only: keep your originals unless SSA explicitly requires them.
Sending it without a fax machine
SSA fax lines receive faxes from online services just like machine-sent ones. Upload your documents as a PDF at faxer.me, enter the office's fax number, and pay for that single fax — $1 for the first page and 25¢ per additional page, with no subscription — then save the delivery confirmation. If your documents are still on paper, scan them with your phone first (see how to fax a PDF).
After you send
Give the office two or three business days, then call to confirm the fax reached your file. Faxes to a busy field office occasionally need a resend, and confirming beats discovering a gap in your file at decision time. Keep your transmission confirmation until the matter is resolved.

What is the fax number for Social Security?
There isn't a single national one for the public — each SSA field office has its own fax number, usually starting with 833 or 844. Get the number from the letter SSA sent you, from the office locator at ssa.gov/locator, or by calling the office or 1-800-772-1213. Faxing the office that actually handles your case matters, because that's where your file lives.
Is it safe to fax documents with my Social Security number?
Faxing to a number provided by SSA is a routine, accepted channel — the fax arrives on SSA's receiving systems, not a shared machine in a lobby. The main risk is a misdialed number, so double-check the digits, use a cover page, and put your claim number rather than your full SSN on individual pages when your SSA letter allows it.
Can I fax my birth certificate to Social Security?
Usually not. For applications that prove identity, age, or citizenship — like a Social Security card — SSA requires original documents or copies certified by the issuing agency, and faxes or photocopies aren't accepted. For most other paperwork (pay stubs, forms, medical evidence for disability claims), fax is fine. When in doubt, call the office and ask before sending.
How do I know my fax reached Social Security?
Your fax service's confirmation proves the office's fax system accepted every page — save it. Then call the office after two or three business days and ask them to confirm the documents are in your file. SSA doesn't send automatic receipts for faxes, so that follow-up call is the only positive confirmation.
