No, they don't.
UPS will just dump a package at the door.
USPS will just dump your package at the door.
DHL will just dump your package at the door.
FedEx is the only one that has never done that to me. I have ALWAYS had to sign FedEx packages.
Again why I like DHL, but if the delivery guy at the office has a DHL package going to my home, he'll actually bring it up to the office for me... So I don't have to screw with missed pickups... And that's all without asking.
UPS always makes me sign for packages here. They are much easier to pick up package from around here too. (Fed Ex is a block from UPS, it's their hours, their notifying via phone calls, and letting you pick something up from the side door after hours).
