How to Fax Documents to Social Security

Social Security does not use one public fax number for every claim and office. The correct destination is usually the local office handling your case or the number printed on an SSA letter.

Before faxing, check whether the requested document can be uploaded through your Social Security account. The agency’s Upload Documents service can provide a clearer electronic record when it is available for your request.

Find the correct office

Use the official Social Security office locator and enter the ZIP code associated with your case. Call the office if the fax number is not shown or if you are unsure which unit should receive the document.

If an SSA notice provides a return fax number, use that number and include the notice’s barcode, reference page, or case identifier exactly as instructed. Those details help route your submission.

Do not fax original evidence

Many applications require original or certified identity, citizenship, immigration, marriage, birth, or death records. The SSA explains that original or certified documents must be mailed or taken to an office when requested. A scan sent by fax does not become an original.

Fax is better suited to forms, statements, and copies that the office has specifically agreed to accept. When in doubt, ask the office before sending sensitive documents.

Prepare a useful fax packet

1. Put the SSA letter or requested response page first when one was provided.
2. Add a brief cover sheet with your name, phone number, case reference, and total pages.
3. Avoid placing a full Social Security number on a general cover sheet unless the office requires it.
4. Arrange attachments in the order named in your cover note.
5. Scan the entire packet and confirm that stamps, signatures, and small text are readable.
6. Fax once and save the transmission report.

Do not assume a successful transmission completes the benefit request. Check your online account, mail, or the local office for confirmation and follow-up questions.

If the deadline is close

Call the number on the SSA letter. Explain that you are trying to meet a deadline and ask whether fax, upload, mail, or an in-person visit is the accepted method for your specific evidence. Record the date of the call and the instructions you received.
