The phrase "package tracking" refers to the process of monitoring and recording the location, movement, and delivery status of a package or shipment. This is typically done using a unique tracking number or barcode, which is assigned to the package and can be used to access information about its location, transit times and expected delivery date. Package tracking is commonly used by courier services, shipping companies and online retailers to provide customers with real-time updates on the status of their shipments. This information can be accessed through various methods, including online tracking systems or by contacting the shipping company directly.
