Social Security fax number (find your office’s fax)

Checked against ssa.gov on November 11, 2026

There’s no national Social Security fax number. Each field office has its own, listed in SSA’s office locator: search your ZIP code at ssa.gov/locator, open your office’s information, and look under “Contact numbers” for “Fax”. If an SSA letter or employee gave you a number, use that.

Find your office’s fax number

  1. Go to ssa.gov/locator and search by your address, city or ZIP code.
  2. Click Office information for your office.
  3. Under Contact numbers, copy the Fax number.

How to fax it

  1. Find your office’s fax number as above, or use the one on your SSA letter.
  2. Add a cover page saying what the documents are for, with your name and Social Security number.
  3. Send it from dimefax.com/send.
  4. Keep the delivered confirmation. Dimefax shows the date and time it went through.

Tips

Dimefax costs 10¢ a page and you’re only charged if the fax goes through. On the web, page credits come in packs of 50 for $4.99, 100 for $9.99 or 200 for $19.99; the Dimefax iPhone app also sells 10 for $0.99. Credits you don’t use stay in your account and last as long as you fax once a year.

Where these numbers come from

Dimefax isn’t part of, or endorsed by, the Social Security Administration. We copied these numbers from ssa.gov on November 11, 2026. Agencies change their numbers: if your letter, notice or form gives a different one, use that.
