Quote from: JohnGalt on November 25, 2012, 12:26 amIf you use the wrong +4 but the right ZIP for the ZIP+4 what do you think would happen? Currently awaiting an order that I accidentally did this, hope nothing too bad will happen :-\It'll just get more attention because it'll initially get routed to the wrong route within the zip code area, I think. So long as there's nothing else suspicious about it, I expect it would show up a little later than otherwise once it's corrected by the guys at the post office.The problem, of course, is that this means the thing has to be checked by human eyes that do more than glance at it on a conveyor belt or something. I don't remember where I read that's how it works, but I have a vague memory of reading it somewhere reliable.Thanks for the answers, all. I guess the vendor who didn't use it even though I gave it to him just didn't know what it was or was so used to buyers giving wrong addresses he just cut it off to be safe.
