Other carriers, such as UPS and Fed Ex, are not able to deliver packages to mailboxes in the Post Office.Every time I get greeted with the same thing: it’s been shipped. I can’t see paying extra so I can track how slow it’s taking.i've recently purchased an ebay item where the seller used the usps priority mail to ship it..kindly enough sent me the tracking information for it...so naturally i go to the site to get tracking information..a lie.The prefix is use to route the package in the USPS main plants.So you see that the IMpb barcode actually combines routing and tracking!
