I have had a manufacturer ship directly to my home when replacing (same model new actual firearm and different serial number) and the delivery guy left it sitting on my deck by my front door when I wasn't home; good thing that I live in Alaska, probably not a smart practice in a lot of places! No FFL involved on my end.
I'm not sure I'd put that info in print. It was illegal. Not sure on who's part, but a new serial number mandates a FFL participation.
