The idea here is that the package goes missing in transit. Kinda like a reverse DNA. It will get scanned at the post office and maybe at the sorting facility before it becomes just a blank box.

I understand your point, but If It happens at their depot whilst already allocated to Its delivery point, It'll be Identified against the details on the carrier's manifest- weight, dimensions, consignor & consignee. A label will be generated thereafter.

Moreover, a lot of major carriers place packages/boxes on their conveyor belt and take photos of all four sides prior to allocating them to their designated area. In the event of unidentifiable packages, the photos serve as a point of reference. I'm not suggesting your method won't work, but rather stating how goods are usually handled and processed.
