usps tracking by scan

usps tracking by scan allows users to track the progress of a package using the barcode scan associated with the shipment. This feature is especially useful for packages that have been shipped using USPS services such as Priority Mail or First-Class Mail. When a package is scanned at various points during its journey, the tracking information is updated online, allowing the sender and recipient to monitor the package’s location and estimated delivery time. USPS tracking by scan provides transparency and helps ensure that packages reach their destination on time.
