How to track a USPS package
To track a USPS shipment, enter your tracking number above into our universal search tool. Our system automatically recognizes United States Postal Service tracking numbers and displays your complete shipment history on one screen. Alternatively, you can view tracking information directly on the official USPS website by entering your identifier into their search bar. Both options display status scans from initial acceptance through final delivery.
About USPS
The United States Postal Service, often abbreviated as USPS, is the independent postal authority responsible for providing mail service throughout the United States and its associated territories. Operating an extensive network of distribution facilities, post offices, and delivery routes, USPS handles billions of items every year. Its coverage extends to every residential and business address across the country, including remote rural communities, military bases overseas, and island territories.
USPS offers a broad selection of shipping solutions designed for different transit speeds and package sizes. These range from standard retail mail services to specialized commercial package options used heavily by e-commerce merchants. In addition to domestic movement within the fifty states, USPS coordinates cross-border mail dispatch with postal authorities around the world. Packages moving internationally are handed over to destination postal administrations after clearing local customs authorities.
Where USPS delivers
USPS maintains universal service obligations covering every location in the United States, including Alaska, Hawaii, Puerto Rico, Guam, and the US Virgin Islands. Domestic shipments move through a vast national network composed of automated processing centers, surface distribution routes, and contracted air transport lanes. For cross-border shipping, USPS serves as the outbound processing agent within the United States. Once an international package crosses the national border, USPS hands off the item to the designated national postal service or partner carrier in the recipient country.

USPS tracking number format
Most USPS numbers are 22 digits starting with 94, 92, 93, or 95 (Priority Mail commonly starts 9400 or 9205). International items use the 13-character UPU format ending in US, the first letter signals the service: E = Express, R = Registered, C = parcel, L = letter-post.
Format example
- 9400 1000 0000 0000 0000 00
- EA 000 000 000 US
- 92 0000 0000 0000 0000 0000 00
Patterns vary by service. Paste whatever you have and we will detect the carrier for you.

What each status means
- In Transit to Next Facility, Arriving Late
- The parcel missed its expected window but is still moving. USPS is the only major US carrier that flags lateness explicitly.
- Shipment Received, Package Acceptance Pending
- USPS has the sender's manifest but hasn't individually scanned your parcel yet, common with bulk shipper drop-offs.
- Available for Pickup
- The item is waiting at your local Post Office; bring ID to collect it.
How long is normal for USPS?
It is common for postal shipments to experience gaps between tracking updates while traveling along major transport corridors. Brief pauses in scanning do not automatically mean your parcel is lost or delayed beyond normal ranges.
Days 1 to 2
Initial electronic receipt or facility acceptance occurs. If status remains on Shipping Label Created, the merchant may not have physically dropped off the package yet.
Days 3 to 5
The parcel moves through sorting facilities. Pauses of two or three days often happen while items travel across long distances on trucks or freight planes.
After 7 days
For domestic standard services, a week without new scans suggests a potential delay. Check your delivery address details and monitor for updated sorting facility events.
After 14 to 21 days
International shipments or delayed domestic packages reaching this window warrant further action. Contact the sender so they can initiate a formal inquiry with USPS.
USPS tracking not updating?
Tracking progress can sometimes pause due to operational factors along the shipping route. Understanding why these interruptions happen helps keep package delivery in perspective.
- Long transport gaps between hubs
- Packages traveling across multiple states move in bulk transport containers that are only scanned upon arrival at the next major distribution center.
- Label created but not handed over
- Sellers frequently print shipping labels in advance. Tracking stays on Shipping Label Created until the physical package enters a postal facility.
- Customs processing delays
- International shipments must pass clearance checks by border control agencies, which can pause tracking updates for several days.
- Weekend and holiday pauses
- Processing centers operate continuously, but regular residential deliveries and local post office operations observe public holidays and Sundays.
- Unreadable barcode labels
- Damaged or smudged shipping barcodes require manual sorting, which temporarily slows down updates until the label is manually reviewed.
What to do next
- Verify that the tracking number was entered correctly without extra spaces or missing characters.
- Allow two to three full business days for transit updates when parcels travel long distances between state hubs.
- Check secondary delivery locations around your property, including porch corners, side doors, and neighbor mailboxes.
- Reach out directly to the merchant or sender if tracking shows no physical facility acceptance after several days.
USPS customs & handoffs
International shipping with USPS involves coordination between US postal facilities and national postal networks around the globe. When a shipment originates in the United States, USPS collects the item, processes it through a local sorting center, and forwards it to an international service center. At the international service center, the parcel receives an export scan before being loaded onto international transport.
Upon reaching the destination country, the parcel is turned over to local customs authorities for inspection and clearance. Once cleared, final delivery is executed by the national postal administration of that foreign destination. Universal Postal Union standards allow the original USPS tracking identifier to function across both networks, and parceltracking.com consolidates these combined carrier updates into a single unified tracking view.
Tips for tracking USPS parcels
Save your tracking number immediately
Store your tracking code in a safe digital note or bookmark your tracking results page so you can easily recheck progress later.
Distinguish label creation from acceptance
Remember that Shipping Label Created means an address label was printed, whereas Accepted means USPS physically received the package.
Check secure secondary drop areas
Postal carriers frequently leave parcels in parcel lockers, side porches, or behind large plants to keep them protected from weather and view.
Monitor foreign postal tracking internationally
When an international parcel leaves the United States, try pasting the standard tracking identifier into the destination country national postal tracker.
Contact the seller for formal claims
Senders hold the original commercial contract with USPS. If a parcel is genuinely lost, the seller must initiate missing mail searches or claims.

USPS tracking questions
USPS scans at fixed checkpoints and typically refreshes about once a day, so a package can move for a day or two between scans. If there is no movement for 5+ days, the parcel may be delayed in processing; after 7 days you can file a Missing Mail search with USPS.
Usually 22 digits starting with 94, 92, or 93 (e.g. 9400 1000 0000 0000 0000 00). International shipments use 13 characters like EA123456789US. Certified and Registered Mail also use the 22-digit format.
