With advances created by the Internet, The Social Security Administration (SSA) now offers a variety of online services for individuals who wish to file for social security online, including retirement benefits, disability benefits, survivors' benefits, or Supplemental Security Income (SSI) benefits. To file for social security online, visit www.ssa.gov. For assistance, consult with a qualified social security attorney. Additional tasks can be managed online once your benefits application has been completed and submitted. You can request a password which allows you to change your address or phone number, request a replacement Medicare card, ask for a proof of income letter, change your direct deposit banking information, and view your records.
