USPS tracking by tracking number
Use the number from your USPS receipt, label or retailer shipping confirmation—not the shop’s order number. Paste the complete identifier into the tracker above and select Track USPS package. Spaces in a displayed number can be removed automatically, but letters and leading zeros must be preserved.
When USPS data is available, the result can show the current status, latest processing location, scan history and delivery information. Some mail classes do not include end-to-end tracking, and international items can display fewer events after a foreign postal operator takes control.
How to track a USPS package
- Find the postal tracking number. Check a Post Office shipping receipt, insurance receipt, USPS.com confirmation, retailer shipping email or the peel-off portion of a USPS label.
- Enter the full number. Do not substitute a store order ID.
- Read the newest USPS event. Look at the status wording, location and date, then expand the timeline for earlier scans.
A newly printed label can appear before USPS accepts the mailpiece. If the page shows Pre-Shipment, the most useful next event is normally an acceptance or facility scan.
What does a USPS tracking number look like?
Many domestic USPS identifiers are long numeric strings, commonly shown with spaces for readability. Some international postal identifiers use two letters, nine digits and a country suffix such as US. The exact pattern depends on the service.
Safe UI examples sourced from USPS public tracking guidance:
- domestic-style display:
9400 1000 0000 0000 0000 00; - international-style display:
CP 000 000 000 US.
These are examples, not active packages. Not every USPS mail service includes tracking.
Common USPS tracking statuses explained
| USPS status or event | What it usually indicates | Useful next step |
|---|---|---|
| Pre-Shipment / Shipping Label Created | The sender created a label, but USPS may not yet have the item. | Wait for an acceptance scan or confirm handoff with the sender. |
| Accepted / USPS in Possession of Item | USPS recorded receipt of the mailpiece. | Follow the next origin-facility event. |
| Arrived at USPS Regional Facility | The package reached a processing hub. | Check for a departure or onward-processing scan. |
| Moving Through Network | USPS is routing the item through its network; not every movement produces a location update. | Monitor the timeline and estimated delivery information. |
| In Transit to Next Facility | The package is expected to continue to another facility. | A new scan may appear only when it reaches the next processing point. |
| Arriving Late | USPS expects the item later than the prior estimate. | Continue tracking and check service alerts if the delay is widespread. |
| Out for Delivery | The item is with the local delivery operation for an attempt that day. | Make sure the mailbox or delivery area is accessible. |
| Delivered | USPS recorded delivery to the address or another stated location. | Check the exact delivery note, mailbox, parcel locker, reception and household members. |
| Available for Pickup | The item is being held at a listed Post Office location. | Follow the official pickup instructions and identification requirements. |
| Alert | An issue may require attention or change the normal route. | Open the event details and follow the USPS instruction shown. |
Why is USPS tracking not updating?
USPS tracking is based on postal events, not continuous location sharing. A quiet timeline can occur while a package moves between plants, waits for processing, travels on a weekend or holiday, passes through customs, or transfers to or from another postal operator.
| Situation | Possible reason | Recommended next step |
|---|---|---|
| Number not found | Typo, order number used, label created very recently or service without tracking | Recopy the number from the shipping source and confirm the mail class includes tracking. |
| Pre-Shipment only | Label exists but USPS has not recorded possession | Ask the sender when the item was handed to USPS. |
| Moving Through Network with no location change | Transit between facilities or milestone-only updates | Keep monitoring the latest estimate and scan date. |
| Arriving Late | The prior delivery estimate is no longer expected | Check the timeline and USPS service alerts; wait for the next scan unless USPS requests action. |
| Delivered but missing | Mailbox/locker delivery, reception or household handoff, safe location, delayed scan notification or misdelivery | Check every stated location, then follow USPS help for a missing or misdelivered package. |
| International tracking stops | Destination-post handoff or limited event exchange | Try the same number with the destination postal operator and check for a local identifier. |
International USPS tracking and postal handoffs
An international package can move through USPS, customs and a destination postal service. The original number may continue to work, but the wording and frequency of events can change after handoff. Customs processing is not the same as a delivery scan and may not update at every internal step.
If the timeline names a destination carrier, use that carrier’s tracking page as a second source. Keep the original USPS number because it can remain the reference connecting both parts of the journey.

Quick answers
USPS tracking FAQ
How do I track a USPS package?
Paste the USPS tracking number into the form above and select Track USPS package. The result will show available carrier events in chronological order.
Why does USPS say “Pre-Shipment”?
The label and electronic shipment information exist, but USPS may not yet have scanned the physical item. If the status remains unchanged, ask the sender when the package was handed over.
Why is USPS tracking not updating?
The item may be travelling between processing points, waiting for a scan, passing through customs or affected by a delay. USPS does not publish a continuous GPS location for ordinary packages.
What does “Moving Through Network” mean?
USPS is continuing to route the package through its processing and transportation network. The next public update may appear when the item reaches another facility.
What does “Arriving Late” mean?
The package is still in the USPS network, but the previous delivery estimate is no longer expected. Review the newest scan and any service alert before deciding whether to open an inquiry.
What should I do if USPS says delivered but the package is missing?
Read the delivery note and check the mailbox, parcel locker, porch, reception, household members and nearby safe places. If it remains missing, use the official USPS status-help and Missing Mail resources.
Can 11Tracking contact USPS for me?
No. 11Tracking cannot contact a postal employee, change delivery instructions, start a mail search or file a claim.
Where can I find official USPS support?
Use the official links in the Need official USPS help? section above. Those pages are operated by USPS and provide the appropriate next steps for delayed, missing or misdelivered mail.
USPS and related marks belong to the United States Postal Service. Their use on this page identifies the carrier only and does not imply endorsement.
Tracking events and delivery estimates come from connected tracking services and carriers. Updates may be delayed, incomplete or revised. 11Tracking does not transport packages and cannot change a delivery.
After you track a parcel, its number is added to the page address so the result can be refreshed or shared. Anyone with that link can use the number, so share it only with people you trust.
