Social Security fax number

There is no single Social Security fax number. Your case is handled by one office, and that office prints its fax number on the notice it sent you, so your letter is the first place to look. If you do not have it, pick your state below for the numbers Social Security published for its offices.

ProntoFax is an independent fax service. We are not affiliated with, endorsed by, or connected to the Social Security Administration.

How we verify fax numbers

Every number on this page was published by the agency itself. The two columns beside it say when that number was last confirmed, and what confirmed it.

The Verified by column says which of these it was:

Agency website the agency publishes this number. The date is the day we read it from their page or their published file.

ProntoFax user a fax sent through ProntoFax reached this number and the receiving machine confirmed it. The date is the most recent delivery.

ProntoFax automation we called the number and heard a fax tone answer. Nothing is sent and the call ends as soon as the line answers.

Needs verification recent attempts to this number did not go through. It stays listed because the agency still publishes it, but check it against your own letter before you send.

The date is colored by how long ago it was:

Within 90 days 91 to 270 days Over 270 days

We never add a number because someone faxed it. A number appears here only if the agency published it. A delivered fax can confirm a number, but it can never create one.

What Social Security accepts by fax

Social Security asks you to send documents to the office handling your case, and your letter says where. These are the kinds of paperwork people commonly fax:

Forms the agency asked you to complete and return
Proof of identity, age, or citizenship when a notice requests it
Medical and school records for a disability claim
Wage, income, or resource documents for a review of your case
Appeal forms, sent by the date printed on your notice

Before you send

Put a cover sheet on the front so the office can match your fax to your case. Include:

Your full name as it appears on your Social Security record
The last four digits of your Social Security number
The claim or notice number printed on your letter
A daytime phone number
The number of pages, including the cover sheet

If Social Security sent you a barcoded cover page, put that page first instead. The barcode files your fax against the right case automatically, which a handwritten cover sheet cannot do.

Keep your delivery confirmation. If the agency has no record of your paperwork, that confirmation is the only proof you have of what you sent and when.

Confirm the number on the letter you received before you send. Offices change fax numbers, and a number that worked before may not be the one holding your case now.

Questions about faxing Social Security

What is the Social Security fax number?

There is no single national number. Social Security handles your case at one office, and that office prints its fax number on the notice it sent you. Use the number on your own letter rather than one from a directory site.

What if I do not have the letter?

Start from the official contact page linked above and ask which office is handling your case and where to send your documents. Sending paperwork with your Social Security number on it to an unverified number is not worth the risk.

Can I fax medical records for a disability claim?

Yes, when the agency has asked for them. Send the request letter as the first page of your fax. It carries a barcode that files the records against your claim automatically.

How do I prove I sent it?

ProntoFax emails you a receipt once the receiving machine confirms delivery, showing the date, the destination, and a copy of exactly what was sent.

How much does it cost?

$2.99 for one fax of up to 25 pages. No subscription and no account. Your card is held and only charged once delivery is confirmed.
