Yup. If the person has a Stamps.com account or whatever the hell it is called they can generate a tracking number...and then forget about it. Keep in mind that the USPS tracking system, when we were still at the USPS, was damn near worthless. It's real purpose is to track the USPS employees themselves, in particular the carrier. The management clowns at the USPS realized that they could use it for tracking packages as a secondary function. The carrier has (had) to scan several different spots on their routes daily to show where they were at any given point during the day. This is how management was able to keep adding to the carriers routes, eventually doing away with some individual routes...which in turn led to a reduction in carriers...
