postal service track a package is a process that allows customers to follow the progress of their shipment through the postal system. To track a USPS package, you can use the tracking number provided at the time of shipment. By entering this number on the USPS website or through their mobile app, you can see detailed information about the package’s journey, including departure and arrival scans, estimated delivery date, and any issues or delays. USPS tracking services also offer email notifications, allowing you to stay informed about your package’s status as it moves through the delivery process.
