How to fax your local Social Security office

There is no single Social Security fax number. Social Security has field offices all over the country, and each one has its own fax number. Your forms and documents go to your own office, so the number you need is that office’s number. Our Social Security fax numbers by state list every office’s number with the date we read it.

Where the fax number comes from

Social Security publishes a file of its field offices, with each office’s address, phone number, fax number and hours. That file is where the numbers on our state pages come from, and each page shows the date we read it.

Social Security’s own office locator shows the same thing for one office. Its contact numbers can include a fax line. If your office shows no fax number, call the office and ask for it. A number from a forum or an old post can be out of date, and a fax sent to the wrong office does not reach yours.

How to find your office

1. Search Social Security’s office locator. It takes an address, a city, a state or a ZIP code. Open your office’s details to see its contact numbers.
2. Check it against our state page. Pick your state on our Social Security fax numbers by state page. For example, the Wisconsin page lists every Wisconsin office with its fax number.
3. Read the number digit by digit before you send.

What the office takes by fax

Social Security’s forms page says you can fax or mail any paper form to your local office, unless the form tells you otherwise. Its page on submitting forms and documents says the same for your paperwork: gather your documents, including any forms you filled out, then find your local office and send them by fax, by mail or through the office’s drop box. Many forms and documents can also be uploaded online through your my Social Security account.

Read the form’s own instructions first. If it names a different place to send it, follow the form.

Some things need a visit. The office locator says you must visit a Card Center if you only need a new or replacement Social Security card, need to update your personal information, or your employer asked you to visit a Social Security office. If an office asks you to come in, make an appointment first.

If your documents go to a different agency, such as your state Medicaid agency or the IRS, our page on faxing a government agency covers where those go.

What to put on the cover sheet

A plain cover sheet helps the office match your pages to your record. Put on it:

• Your full name, as it appears on your Social Security record
• The last four digits of your Social Security number
• The claim number or notice reference, if your letter has one
• What the documents are for, such as “Form SSA-44 and proof of income”, or the date of the letter that asked for them
• A phone number where the office can reach you
• The number of pages, including the cover sheet

How to send it from your phone

You do not need a fax machine. You need your phone and the pages.

1. Lay each page flat in good light. Photograph one page at a time, straight down, with the whole page in the frame.
2. Or upload a PDF. If you filled out the form on a computer, upload that instead.
3. Add a cover page. You can type one in the app, or photograph your own cover sheet as the first page.
4. Check every page in the preview. Retake any page that is blurry, dark or cut off.
5. Enter your office’s fax number. We check that the line can receive a fax before you pay.
6. Pay $2.99 and send. It is one flat price for up to 25 pages. Your card is held, not charged, until the receiving machine confirms delivery.

You get an email receipt with the delivery time, the page count and the number it went to. Keep it, and keep your originals. A delivered fax means the pages reached the office’s machine. It does not mean the office has processed them, so call the office if you hear nothing.

If you are worried about how a photographed page will look on the other end, a test fax sends your own pages to a ProntoFax test line and shows you what came through.
