Overview
USPS, the United States Postal Service, is a major postal operator that handles domestic mail and parcel delivery across the United States and also participates in international delivery networks. Many online orders, personal shipments, returns, and marketplace parcels may travel fully or partly through USPS.

How to track a USPS parcel
You can track a shipment using the tracking number provided by the sender, retailer, or marketplace. USPS tracking is commonly available on the official USPS website, through the store where you placed the order, or on a universal tracking page when the parcel is handed between carriers.
If a shipment involves more than one carrier, the tracking history may show updates from the original shipper, a consolidator, customs processing, and USPS for final delivery. In those cases, the latest scan may appear on the seller's order page before it appears elsewhere, or the reverse.
Common tracking updates
Tracking messages vary by service and route, but users often see updates such as:
- Label created or pre-shipment — shipment information was submitted, but USPS may not have the parcel yet.
- Accepted or USPS in possession of item — USPS has received the package.
- Arrived at USPS facility or departed USPS facility — the parcel is moving through the network.
- In transit or moving through network — the item is traveling between processing points.
- Out for delivery — the shipment is with the local carrier for delivery.
- Delivered — USPS recorded the parcel as delivered.
- Available for pickup or similar — the item is being held for collection.
- Delivery attempted or notice left — delivery was not completed on that attempt.
Some scans can appear out of sequence, and it is normal for tracking to pause briefly while a parcel is moving between facilities or awaiting the next physical scan.
Delivery expectations
Delivery time depends on the mail class, destination, weather, seasonal volume, address accuracy, and whether the parcel is moving only within the United States or through an international route. Nearby domestic shipments may update quickly, while cross-country or cross-border deliveries can take longer and may show fewer detailed scans between major checkpoints.
For international shipments, USPS may handle only part of the journey. Another postal operator or delivery company may perform the first mile or final mile, which can affect how often tracking updates appear.
When to check the official website or contact the seller
Check the official USPS website for the most current scan details, delivery-related updates, or notices related to attempted delivery or pickup. If the tracking number does not show activity yet, the sender may have created the label before the parcel entered the mailstream.
You should contact the seller or sender when:
- The tracking number appears invalid on the day it was first shared and no later update follows.
- The parcel remains in a pre-shipment or label-created state for an extended period.
- The delivery address may be incomplete or incorrect.
- The shipment is part of an order that may be split into multiple packages.
- The parcel shows delivered but you have not received the item and need order-specific help.
If a package is delayed, it is often best to allow a little time for the next scan to appear, then compare the tracking on USPS with the seller's order page for the clearest picture of where the shipment is in the process.
