I couldn't find a link on how to verify my account. Most sites require a photo id and a utility bill and sometimes a site specific form. Is there a link on ACR? I couldn't find any info in the FAQ
not to certify your account - the only time you need to fill out a form like what you're describing is if you decide you want to get the debit card they offer for withdrawals, then you will need to send them a scan of your SS card and you will need to fill out a basic form that they provide. But that is only if you want the debit card option (you can have them load your money onto a prepaid card instead of having them mail you checks or WU/MG transfer.)
