Package tracking

Package tracking or package logging is the process of localizing shipping containers, mail and parcel post at different points of time during sorting, warehousing, and package delivery to verify their provenance and to predict and aid delivery.

Package tracking developed historically because it provided customers information about the route of a package and the anticipated date and time of delivery. This was important because mail delivery often included multiple carriers in varying environmental circumstances, which made it possible for a mail to get lost.
