tracking numbers
A tracking number is a unique code assigned to a package or shipment, allowing both the sender and recipient to monitor its progress during transit. This number is typically provided by shipping companies like UPS, FedEx, or USPS and can be used on their websites or apps to see where the package is at any given time.
When a package is shipped, the tracking number is generated and linked to the shipment's details. As the package moves through various locations, updates are recorded and can be accessed online. This helps ensure that the package arrives safely and on time.
