I'm not the expert on this, so maybe Rick McQuillan will weigh in, but...
when using USPS, the number we all refer to as a "tracking number" is usually a "delivery confirmation number".
The difference being that USPS does NOT scan it into their system every step of the way. They scan it at receipt and at delivery. It's not designed to show you where the package is while it's intransit. It's designed to show the shipper that it has been delivered. It can also function to show the buyer that it has been shipped.
I'd wait another week before panic sets in.
