Seriously?
Those stickers are placed there by movers, who are moving 18-wheelers of things across the country. Every box, every item gets a sticker. Then when you arrive at your new place, the movers come, unload everything, and give you a list to check off every individual item as it gets put into your new place.
I had my employer pay for my stuff to be moved; I have so few things that they can fit in my car (a sedan) but it was easier to have non-fragile items moved instead of drive them nine thousand miles. Despite that, my list of things to check off was still 30 or so long.
