AND TO Yurchie "Only put down numbers you were issued by the SSA. "

Thank you. The reason I, and others I know are confused about the question is because of the phrase in parenthesis (include all numbers you have ever used). I never would have thought to put any number that wasn't issued by the SSA otherwise. It's specific in saying numbers used and not numbers issued. I have been thinking too much about it. At a DACA assistance workshop they said they weren't sure about that question yet that's why I wanted to know what actual applicants are doing. I think I will just leave it blank.
