Room labels do most of the unloading work in a move. The best ones are obvious from a distance, repeatable across the whole house, and plain enough to survive a home printer.
Use the room first and the box detail second. A label that says KITCHEN - BAKING is easier to unload than one that only says MIXER or GLASSES.
Apartments, townhouses, and multi-floor homes get the biggest benefit because helpers can sort boxes before the rooms are fully set up. That saves repeated lifting later.
