whoa fella, i don't know, but this might me news to you, it was to me. we get our address information from the USPS. UPS pays money for the USPS address management database. how is that for an explantion to our address woes. then you get into the zips that are postal in nature only. those zips are for the post office boxes and the post offices themselves. those zipcodes don't relate to actual physical addresses and won't come up on any USPS zipcode boundries map. some "corporate" zipcodes are the exception. large companines and some colleges have their own zipcodes, which may or may not be on the map. UPS has the ability to create an "alais" address in the new system, it's just a matter of getting mgmt. and the driver together to input that info.
as far as address correcting the package on area, i'd rather get it delivered first off, then bill the shipper to get their attention, because the next driver on that delivery might not know where it really needs to go, so we loose at least a day, if not a week if it has to be postcarded. Then it still ends up with an address correction.
If the shipper wants to dispute the billing charge, that's fine but i hope they update their address book also.
