A package tracker is a digital tool or system used to monitor the shipping progress, real-time location, and delivery status of a mail parcel. How It Works
Tracking ID: The carrier automatically generates a unique tracking number containing letters and numbers when a package is shipped.
Checkpoint Scans: The package barcode is scanned every time it reaches a new facility, such as a sorting center, customs checkpoint, or delivery hub.
Status Updates: The barcode scan instantly updates the tracking database, allowing the sender and receiver to see transit progress online. Types of Package Trackers USPS Tracking® – The Basics
