The address that you use to mail a completed form will vary by the situation. Use the following guidelines to determine the proper mailing address:
If a Social Security office has mailed you a form for completion, mail it back to the requesting office. They may have provided a return envelope for this purpose.
Certain forms have specific mail boxes that receive them and these will be designated on the form.
If neither of the above are true, mail the form to your local office. To find the office address, use the Social Security Administration’s Office Locator.
Rather than mailing a form to Social Security consider completing the action online. For example, you may request direct deposit of your check by completing U.S. Treasury form SF-1199A and mailing it to your local office, or you can complete this application online.
