USPS Tracking: Track Packages, Mail & International Deliveries
CARRIAGE TRACKING – All-in-One Courier Tracking Service
USPS Tracking
For USPS tracking, enter your tracking number in the tracker above or on usps.com. Most domestic numbers are 22 digits starting with 92, 93, 94 or 95. International numbers are 13 characters ending in “US”, such as EA123456789US. You’ll find the number on your receipt, in the shipping email, or in your USPS.com account. For help, call 1-800-ASK-USPS (1-800-275-8777).
The United States Postal Service delivers to more than 170 million addresses across the US. Whether you’re waiting on a Priority Mail box, an eBay order, or a parcel from overseas that USPS delivers for the last leg, the tracking number is your key to finding it.
This guide covers how to track a USPS package, what each tracking number format means, delivery times by service, what the common statuses mean, and what to do when a package is late or missing.

Can You Change a USPS Delivery Address?
Once a package is on its way, you have a few options:
Some items, such as packages already out for delivery or certain Collect on Delivery shipments, can’t be redirected.
Does USPS Deliver on Weekends?
USPS delivers most mail and packages Monday to Saturday. Sunday delivery is limited, mainly Priority Mail Express and Amazon packages in many areas. If your Amazon tracking shows USPS as the carrier, a Sunday drop-off is normal. If you need to post or collect something at a branch, check our guide to post office opening times.
International Packages Delivered by USPS
Many international parcels are delivered by USPS once they reach the US. Parcels from the UK often start with Royal Mail, and many cross-border e-commerce orders are consolidated by Asendia USA or Landmark Global before USPS handles the last mile. Budget marketplace orders often end with USPS too. Our Temu vs Shein comparison explains how those orders travel.
Gaps in tracking are common while a parcel clears customs or waits for a flight. Once USPS scans it in the US, USPS tracking updates usually become more frequent.
USPS vs Regional Carriers
Some online retailers split deliveries between USPS and regional carriers. If your package isn’t showing on USPS, check whether the seller used OnTrac, which merged with LaserShip and now covers much of the East and West Coasts.
USPS Package Late, Missing or Marked Delivered?
- Check around: mailbox, porch, parcel lockers, neighbours and your building’s office.
- Wait a day: “Delivered” is occasionally scanned early, and the package arrives the next day.
- Submit a Help Request on usps.com if it’s still missing after a day or two.
- File a Missing Mail search if seven business days have passed since mailing and there’s still no sign of it.
- File an insurance claim if the item was insured. Priority Mail includes some insurance as standard.
For online orders, the seller can often reship or refund faster than a USPS claim.
