So only UPS uses the same label to returns?
I saw that method but I still don’t get it how it works.

Its not like returning, you reroute. When you like forgot to pick up the packet its reroute back to warehouse. And they would just see like oh its probably rerouted beacause some issues on carrier.

Ok but you pick up the package anyway, so that information goes to their system. After that, should I go with that box which has delivered status,  to send it back, changing only address?

Im not sure, but its the ups label handling probably overrides old information. And edit the label that was on package.
