How to Track a Package Using Online Delivery Tracking Services

Package tracking

Private investigators may have to track a package as part of an investigation case, or retrace the shipping path of a package already shipped.  Most of the major shipping companies provide a tracking number that can be used on a package tracking website to obtain the delivery status of a package.

In many cases, the carrier will also provide the shipping history, so you can trace the steps along the way. Packages are usually scanned at every major point during the mail stream. For example, the package is scanned when it is accepted at the mail facility, then when it arrives at the next facility (say, via flight to Memphis hub). Then it is scanned again when it arrives at the local mail facility, and scanned again when the package is delivered. The number of transfer or check-in points along the way varies depending on the item, the carrier, the mode of transportation and the destination.
