How to track a UPU package
To track a UPU postal shipment, enter your tracking number into the input field at the top of parceltracking.com. Our system identifies the format automatically and aggregates routing updates across international post operators into a single timeline. Alternatively, you can view tracking status using the official UPU Global Track and Trace portal at globaltracktrace.ptc.post/gtt.web/. Both tracking options allow you to monitor package progress as items move through origin postal facilities, export exchange offices, customs clearance, and local destination post office delivery networks.
The Universal Postal Union, located in Switzerland, is a specialized agency that coordinates international postal services between national posts. This page tracks standardized postal items processed through UPU global postal network frameworks.
About UPU
The Universal Postal Union, headquartered in Bern, Switzerland, serves as the primary governing body for international postal cooperation. Established to ensure uniform mail processing across borders, UPU sets technical standards for mail dispatch, dispatch documentation, and global parcel tracking systems. Millions of postal items move through member networks every day under UPU operational guidelines.
UPU does not directly operate delivery trucks or courier vans on local streets. Instead, national postal authorities like USPS, Royal Mail, Deutsche Post, and La Poste handle physical collection, sorting, transit, and final delivery within their respective countries. The UPU messaging system links these individual national post systems together, creating a unified tracking thread across international borders.
Where UPU delivers
UPU member postal entities cover practically every inhabited region across the globe. International mail flows from origin post offices through specialized exchange hubs known as Offices of Exchange. Parcels cross international borders via commercial airlines, freight haulers, or maritime channels before arriving at destination exchange offices. Once imported, the destination country national post handles final transport and delivery to home addresses or local pickup points.

UPU tracking number format
UPU tracking numbers follow the international S10 standard established for worldwide postal exchange. This standardized format consists of 13 characters beginning with two letters, followed by nine numerical digits, and ending with a two letter country code representing the origin postal administration. The leading two letters indicate the mail service type. For instance, letters starting with C usually denote standard parcel post, E represents Express Mail Service (EMS), R signifies registered mail, and L designates tracked letter post. The final two letters show where the package originated, such as CH for Switzerland, US for the United States, or CN for China. Understanding this structure helps you confirm that your shipping receipt contains a valid international postal tracking identifier.
Format example
- XX 000 000 000 XX
- EE 000 000 000 CN
- RR 000 000 000 CH
Patterns vary by service. Paste whatever you have and we will detect the carrier for you.

- Send item abroad
- The package has left the origin country and is currently in transit aboard international transport.
- Receive item at location
- The destination country postal authority or import hub has scanned the dispatch container upon arrival.
- Held by customs
- The item has been transferred to border control authorities for inspection or duty assessment.

How long is normal for UPU?
International postal shipping involves multiple handoffs between airlines, customs agencies, and national post operators. Because physical scans only occur when containers are opened and processed at major hubs, tracking silence of several days is completely normal.
Days 1 to 5
The item is being collected, sorted, and prepared for international export. It is normal for status updates to take a few days after initial posting.
Days 6 to 14
The parcel is moving across international borders or awaiting import processing at destination customs. Long gaps between updates are common during long distance transit.
After 15 to 21 days
Customs clearance or transit between major sorting hubs may be delayed. Check whether your destination post tracking shows an active local record.
After 30 days
If there are no new scans after a full month, contact the merchant or sender to initiate an official postal inquiry through the origin post office.
UPU tracking not updating?
Tracking stalls often cause anxiety, but gaps in scanning rarely mean a package is lost. Postal tracking relies on physical scans at central distribution hubs, meaning items in transit between countries will not update until they arrive at the next facility.
- Transit between international hubs
- Packages aboard cargo flights or vessels cannot receive physical scans until unloading at the destination import facility.
- Customs clearance inspection
- Border clearance agencies process thousands of items daily. Customs holds can pause tracking movement for several days without detailed notices.
- Last mile carrier handoff
- When a parcel arrives in the destination country, there may be a short delay while the local post scans the item into their domestic system.
- Unscanned transport containers
- During peak holiday seasons, postal containers may wait in queue at sorting facilities prior to opening and individual package scanning.
What to do next
- Verify that the 13 character UPU tracking code was entered correctly.
- Check the tracking page of the destination country national post using the same S10 code.
- Allow several business days for international transit and customs processing.
- Contact the sender or seller to file a postal investigation if tracking remains frozen beyond normal windows.
UPU customs & handoffs
International postal movement under UPU standards involves structured handoffs between independent national systems. When a package leaves the origin country, it receives an export scan at an Office of Exchange. It then enters line haul transit across international borders before arriving at the destination country exchange office. During this international flight or voyage, no intermediate scans are generated.
Upon arrival, local customs authorities inspect the item before releasing it to the destination national post. At this point, the package is scanned into the local domestic network. Tools like parceltracking.com help bridge this gap by monitoring data feeds from both origin and destination postal providers, ensuring you maintain visiblity from initial posting to final doorstep delivery.
Tips for tracking UPU parcels
Keep your S10 tracking code
Save your 13 character tracking number in a safe place, as it remains valid across both origin and destination post systems.
Check destination postal tracking
Once your parcel reaches the destination country, search the local post operator website using the same UPU tracking number for additional detail.
Monitor customs requirements
If your package is delayed at import, check if taxes, duties, or identity verification are required by destination customs.
Contact the merchant first
Senders have direct standing with origin postal operators to open formal inquiry claims if a package encounters severe delays.

Your tracking code is printed on your postal receipt, shipping confirmation email, or merchant order page. It follows the standard S10 postal format consisting of two letters, nine digits, and two country code letters.
Tracking status often pauses while parcels are in international transit or undergoing customs inspection. Scans only update when a package arrives at a major postal hub and is physically scanned by facility staff.
Delivery times depend on the mail service used, distance, seasonal volume, and customs processing speeds. Express mail generally takes 3 to 10 days, while standard international parcels take between 7 and 30 days.
The national postal authority of the receiving country handles final delivery. For example, USPS delivers UPU parcels in the United States, while Royal Mail handles delivery in the United Kingdom.
