Of course they can. How can they not see it? If you simply go online to att.com and look in your account it even shows a picture of the note 7 under "your devices". Mine showed up in less than an hour (the time it took me to get home from Target) after the original Target purchase. If it didn't show up how can they bill you? Or know your monthly payments? Or have your IMEI? Or setup your voice mail? Target has nothing to do with that. In fact, mine was unlocked within 24hrs after purchase at Target so it was pretty obvious ATT had it in their system. I purchased it on the payment plan to get my gift card and paid for it in full when I got home an hour later. You guys are getting BS'd by ATT stores who just don't want to deal with it because just maybe it might take an extra step or 2 but obviously it can be done. I can't be the only one in the world who got a Target device swapped TWICE at 2 different ATT corp stores one of them 1000 and the other 1300 miles from my home and I didn't even have the receipt, boxes or anything other than the phone and the charger (which I kept anyway).
