Is there anything else to Creating an FSA ID? What happens when I use my FSA ID to access my FAFSA form?
When using your FSA ID for this purpose, information such as your name, Social Security number and date of birth will be automatically loaded into your application. This prevents any errors occurring when your verified FSA ID doesn't match the information on your FAFSA form
