> Accepted ID types: For our US customers, you must submit one state-issued driver's license or ID card.

Not sure about GC, but it's quite common to have either a driver license or a non-driver license state ID. It might even accept Real ID which is something you can get through DMV. If you live in the U.S. I highly recommend have a state-issued ID (Real ID would be a wise one at this point for future domestic traveling).
