What is the SSI fax number for the Social Security Administration?

There is no single national SSI fax number. Each local Social Security office has its own dedicated fax line. Use the SSA Office Locator at ssa.gov/locator to find your local office's fax number, or call 1-800-772-1213 to ask for it directly.

Can I fax documents to Social Security for an SSI application or appeal?

Yes. You can fax medical records, the SSA-561-U2 reconsideration form, doctor statements, and supporting evidence. The first page of every submission must include the barcode provided by the SSA — without it, the system cannot route your documents to the correct case file.

What is the fax number for an SSI hearing office (ALJ appeal)?

Each Office of Hearings Operations (OHO) location has its own fax number. Check the hearing notice the SSA sent you — the fax number appears at the top. You can also use the Hearing Office Locator at ssa.gov/appeals/ho_locator.html.

How many pages can I fax to the SSA at once?

Do not fax more than 200 pages in a single transmission. If your submission exceeds 200 pages, split it into multiple faxes and include a barcode cover sheet as the first page of each batch.

What is the fastest way to submit SSI documents without faxing?

The SSA's eSignature and Document Upload service lets you submit forms and evidence electronically through your my Social Security account — no fax, mail, or office visit required. Healthcare providers can use Electronic Records Express (ERE) at ssa.gov/ere for free secure document submission.
