I do them 6 months out. You can do the SS # plus A, but that's not always correct(retired teacher, rairoad retiree, etc.). Just write in "new" and the company will send the client a form to fill in when they get their card.
Almost every company will accept T65ers 6 months out, so they're aware that they don't have a card yet.
But he’s asking about a year from now when no one uses SS numbers anymore.
But if you can write “new” right now and it works, that should be fine in the future.
