Acceptance: The process begins when a package is dropped off at a post office, handed to a carrier, or placed in a collection box.
Initial Processing: Packages are scanned and logged into the USPS tracking system. Data like origin, destination, and dimensions are recorded.
Sorting: Packages are transported to a regional processing and distribution center (P&DC). Here, they undergo initial sorting using automated machinery and manual sorting, where packages are separated by destination ZIP code. This stage determines the routing.
Transportation: Packages are transported between P&DCs using various methods: trucks, airplanes, and trains. The mode of transport is selected based on the distance and speed of delivery. Long-distance transport frequently uses airplanes for speed.
Regional Processing: Packages arrive at a P&DC near their destination. They are sorted again to ensure they are directed to the correct local post offices. More detailed sorting takes place here, down to carrier routes.
Local Delivery: Packages are transported from local post offices to delivery routes. Carriers sort packages based on delivery order and deliver them to individual addresses.
Delivery Confirmation: The delivery is recorded using a handheld scanner, providing delivery confirmation and real-time tracking updates. If the package cannot be delivered, the carrier will leave a notice or return the package.

Examples & Use Cases

E-commerce Shipments: Online retailers rely on USPS to ship products to customers. The efficiency of the network directly impacts the customer experience and the business's success.
Personal Mail: Individuals use USPS for sending gifts, documents, and personal items. Tracking allows senders and recipients to monitor the package's progress.
Business Mail: Businesses send invoices, marketing materials, and other critical documents through USPS, which supports commercial operations.
Subscription Services: Services that deliver products regularly, such as meal kits or beauty boxes, often use USPS for efficient, recurring deliveries.
Returns: Customers return items to retailers using USPS, relying on the tracking to confirm the return's receipt.
