The Social Security Administration does not publish a single national fax number for the public

The Social Security Administration (SSA) handles fax requests through local field offices, not a centralized fax line. If you need to send documents to SSA — such as proof of income, medical records, or corrected information — you will fax to the specific office that handles your case, not to a national number.

The office that handles your case depends on where you live or where you filed your claim. Finding the right fax number requires identifying your local SSA field office first, then calling that office to ask for their fax number and the correct department to receive your documents.

Key Takeaways

  • SSA does not have a published national fax number; you fax to your local field office instead.
  • You can find your local field office address and phone number through the SSA office locator at ssa.gov or by calling 1-800-772-1213.
  • Before faxing, call your local office to confirm they accept faxes for your type of request and get the correct fax number and department name.
  • Include your Social Security number, name, date of birth, and a cover sheet explaining what you are sending and why.
  • Keep a copy of everything you fax and note the date and time you sent it in case you need to follow up.

How to find your local SSA field office fax number

Start by locating your local Social Security field office. Visit ssa.gov/locator and enter your zip code, or call 1-800-772-1213 (TTY 1-800-325-0778) and ask for the office nearest you. The representative will give you the office address and phone number.

Once you have the phone number, call that office directly and ask for the fax number. Do not assume all offices have fax capability or that they accept faxes for all types of requests. Some offices may ask you to mail documents instead, or they may direct you to submit information through your online my Social Security account.

When you call, also ask which department or person should receive your fax. This ensures your documents reach the right person and do not sit in a general inbox.

What documents SSA typically accepts by fax

Social Security offices generally accept faxes for supporting documents related to an active claim or case. Common examples include birth certificates, marriage licenses, divorce decrees, medical records, pay stubs, tax returns, and letters from employers or doctors.

Some offices may fax back confirmation that they received your documents. Others may not. After you fax, call the office within a few days to confirm receipt and ask how long it will take them to review what you sent.

What to include on your fax cover sheet

Always use a cover sheet. Write your full name, Social Security number, date of birth, and phone number at the top. State clearly what documents you are sending and why — for example, "Medical records for disability claim" or "Updated income verification for SSI review."

Include the date and time you are sending the fax. At the bottom, write the name and phone number of the SSA office you are faxing to, so the recipient knows where it came from if there is a routing problem. Keep a copy of the cover sheet and all pages you fax.

When faxing may not be the best option

If you have a my Social Security account, uploading documents through that account is often faster and creates a permanent record in your file. You can create a free account at ssa.gov/myaccount.

For urgent matters — such as a missed deadline or a case that needs immediate attention — calling your local office is better than faxing. A phone call creates a record of the conversation and gives you a chance to explain the situation directly to someone who can take action.

If you do not have access to a fax machine, you can mail documents to your local office or ask the office whether they accept scanned documents sent by email.

Tracking what you send and following up

After you fax, write down the date, time, fax number, number of pages, and the name of the person you spoke with (if you called first). Keep this record for at least one year.

Call the office three to five business days after you fax to confirm they received it and ask when they expect to process it. If they cannot find your fax, you have a record of when you sent it and can resend it or mail it instead.

Frequently Asked Questions

Can I fax to SSA without calling first?

You can try, but calling first is safer. Not all offices accept unsolicited faxes, and your documents may get lost or routed to the wrong department. A five-minute call to confirm the fax number and department name prevents delays.

What if I do not know which SSA office handles my case?

Call 1-800-772-1213 and tell the representative your situation — for example, that you filed for disability or that you receive SSI. They will tell you which office handles your case and give you that office's phone number so you can ask for their fax number.

How long does it take SSA to process a faxed document?

Processing time varies by office and by document type. Most offices scan faxes into your file within one to three business days, but they may take longer to review the contents. Ask your local office for their typical timeline when you call to confirm the fax number.

What if SSA says they did not receive my fax?

Ask the office to check their fax log for the date and time you sent it. If they still cannot find it, mail the documents instead and include a letter explaining that you already faxed them on a specific date. Keep copies of everything you mail.

Can I fax to SSA after hours?

Most fax machines accept incoming faxes 24 hours a day, but no one will process your fax until the office reopens. Call during business hours to confirm the fax number and let them know you are sending something, so they know to look for it.
