I honestly do not see how a box can be identified and forwarded towards the exact, correct address

Put simply, It's Identified when scanned at the collection point, as well as the description documented on the carrier's manifest. When cross-checked, both records will pinpoint the package In question.

Moreover, a lot of major carriers place packages on conveyor belts at their depot, whereby weights, dimensions and photos (of very angle) are taken prior to placing them at their designated section awaiting delivery. This barely scratches the surface of how goods are handled- but gives you a general Idea of how It works.

This Is based on 30+ years of personal experience In the shipping/freight sector, and not just something I've Googled.
