How parcels can be redirected to another address

Question

Recently had to get a parcel redirected and I’ve been wondering how that even works, can someone explain how they’d do it?

Answer 1

Essentially, each parcel has a code on it which when scanned, tells people where to take it (starting point, 1st stop, 2nd stop, …, Delivery point). When you redirect it the route is changed, so the code tells them to take it somewhere else!
