Yes, I understand about drop trailers, but those trailers aren't picked up and moved by linehaul, they first go back to the origin sic to be loaded out to the proper fac's, correct? It's a simple matter for the originating sic to pro the freight before it leaves their barn. Just how many man-hours are wasted everyday by not having the pro numbers on the freight to scan or punch in by hand? When the freight gets separated from the BOL, or gets put onto a trailer that it is not t-conned onto, it can sometimes take hours or days of research to get the freight to the right customer.
