Q: Does The service track packages in real time? → A: Yes, Delivery tracking provides free real-time tracking for all Priority Mail, Priority Mail Express, and USPS Ground Advantage packages, including delivery date, time, and recipient signature capture.

How Does USPS Delivery Confirmation Work in 2026?
This feature operates through the Intelligent Mail Package Barcode (IMpb) system, which creates a unique tracking identifier for each package. This barcode captures scanning events at every stage of the delivery process, from initial acceptance to final delivery.
When you ship with qualifying USPS services, your package receives automatic tracking at no additional cost. The system records each scan point: acceptance at origin facility, departure from local facility, arrival at destination facility, out for delivery, and final delivery confirmation.
The tracking information includes delivery date, time (usually within a 2-hour window), and delivery location. For packages requiring signatures, the system also captures the recipient’s name or “COVID protocols followed” notation when contactless delivery is used.
