How to track my International Post package?

Ordertracker provides a simple solution to track your International Post packages. To begin, you'll need a International Post tracking number provided by the sender or the retailer.

Enter your tracking number in the above field and hit "enter." Our tracker will then fetch the latest tracking details for your package.

You'll see a timeline showing your package's journey, including its current location, transit history, and expected delivery date. This keeps you informed about your International Post package in real time.

Where can I find my International Post tracking number?

Finding your International Post tracking number is usually simple. When you buy an item online or send a package, the tracking number is typically given by the online store or sender. If you're the recipient, the sender often provides it via email, text, or on the order confirmation page.

For online purchases, log in to your store account to find the tracking number in your order history or tracking section. You can also find it in shipping notifications sent to your email or phone.

Once you have the tracking number, you can easily use Ordertracker to monitor your package's progress. This tool shows your package's journey and estimated delivery date.

Why isn't my International Post package moving in the package tracking history?

Dealing with a International Post package that appears stuck in tracking can be frustrating. Yet, there are steps to tackle this. If you've been using Ordertracker and see no progress, start by being patient. Delays, like customs or logistical issues, can arise.

If the delay remains, contact International Post or the sender for specifics. They can offer insight or investigate. Keep your tracking number ready for a smoother process. Sometimes, misrouting or address errors cause delays. Confirm the details provided to you by the sender. Remember, International Post customer service or the sender can help resolve shipping delays.

When I track my International Post package, why does it show as "returned"?

If you're tracking your International Post package and it's marked as "returned", this usually means that the package has been sent back to the sender or the shipment origin location for a specific reason. There are a few common explanations for why a International Post package might be labeled as "returned":

Incorrect address

An unclear or inaccurate address from sender or recipient might lead International Post to be unable to deliver, resulting in a return.

Unsuccessful delivery attempts

If multiple delivery attempts fail, International Post may return the package instead of holding it indefinitely.

Unclaimed package

If the recipient doesn't collect the package within a timeframe from a post office or delivery center, International Post might return it.

Customs issues

International packages can be return due to customs problems like missing or incorrect documents.

If your International Post package is "returned" in tracking, contact the sender or International Post customer service. This clarifies the return reason and lets you explore solutions like resending or refunding. Please note that return procedures can vary based on International Post policies and circumstances.

Why does the International Post parcel tracking timeline indicate that my order cannot be found?

When your International Post parcel tracking lacks information, it may indicate a "cannot be found" message. This happens for a few reasons:

Incorrect tracking number

Ensure your tracking number is accurate. Even a small mistake can prevent the system from recognizing your package.

Delayed update

Sometimes, tracking details might be slower to update in International Post system. Wait and check again later for potential updates.

Recently shipped

If the package was recently sent, it might not be processed by International Post yet. Tracking should appear shortly.

Intergovernmental organization structuring global postal exchanges

The Universal Postal Union is the intergovernmental organization that structures international postal exchanges. It does not transport shipments or operate a distribution network. Its mission is to establish common rules, standards, and procedures so that designated postal operators in each country can accept, transport, clear, and deliver letters and parcels across borders with guaranteed interoperability.

Based in Bern, the institution brings together postal authorities around a body of legal acts, technical tools, and quality management mechanisms. Thanks to this framework, a shipment accepted by a national operator can be recognized, routed, and delivered by another operator in the destination country, while maintaining consistent traceability.

Role of the UPU in global logistics

The UPU acts as a standardizer and technical arbitrator. It defines the rules of exchange between designated operators, promotes common electronic message formats, oversees cooperation with customs, and encourages alignment with other transport chain actors such as airlines and ground operators. The UPU works on process design, service quality, and security, while daily execution is ensured by member posts and their transport partners.

UPU governance structure

Governance revolves around a periodic congress that sets directions and adopts acts, a council responsible for administration and regulatory oversight, and a council dedicated to postal operations. An international bureau provides permanent secretariat services, develops technical standards, and supports operators in their implementation. This architecture allows the common framework to be adjusted to market, technology, and national regulatory developments.

Legal framework and operator responsibilities

The UPU's legal framework includes a constitution, general regulations, and a postal convention with detailed regulations. Designated operators commit to applying these provisions for the collection, processing, exchange, and distribution of international shipments. Obligations cover service quality, security, data exchange, compliance with prohibited content, exception management, and cooperation for inquiries and claims.

Technical specifications for data exchange

To ensure interoperability, the UPU publishes specifications for computerized data exchanges used at each stage of the journey. They describe message content, sequencing, and validation rules.

  • Alert and tracking messages based on standardized events that describe acceptance, movements in exchange centers, transfers of responsibility, customs operations, and delivery.
  • Dispatch and loading pre-advice allowing the announcement of bags, cages, and loading units, as well as planned routes. These messages align physical content and data.
  • Transport interfaces to notify handover and receipt with air or ground carriers, with loading unit references and reliable timestamps.
  • Advance electronic data related to commercial shipments, including goods description, origin, declared value, and seller and buyer information, for risk analysis and customs procedures.

Numbering and tracking system for shipments

The UPU standardizes a tracking identifier composed of two letters, nine digits, and two letters indicating the country of origin. Alphanumeric prefixes indicate service categories, and the suffix uses the alpha-2 country code. This identifier is printed on the shipping label, encoded as a barcode, and conveyed in electronic messages to ensure consistency between scans, transfers, and tracking updates.

This coding allows the destination country's operator to recognize the item, integrate it into their own systems, and produce harmonized tracking events. The presence of a check digit enhances reading integrity and limits errors during sorting operations.

Standardized operational process

The journey of an international shipment follows a sequence of operational milestones based on UPU standards. This sequence may vary depending on object categories and transport links, but it follows a common logic.

  • Admission at the counter, partner agency, or by pickup. The item is accepted, labeled, and associated with an S10 number.
  • Domestic consolidation in national processing centers, then transfer to a departure exchange center.
  • Dispatch constitution where items are grouped by destination in identified bags or loading units. Announcement messages are sent to the destination partner and carriers.
  • International transport by air, road, rail, or sea depending on the chosen routes.
  • Arrival in the destination country with receipt of dispatches at an arrival exchange center, integrity check, and routing to customs circuits.
  • Customs processing including risk analysis, document verification, and any recipient formalities.
  • Delivery by the designated operator of the destination country, with home delivery, delivery against signature, availability at a postal contact point, or automatic locker according to local service.

Customs cooperation and advance data

Cooperation with customs administrations relies on the exchange of structured advance electronic data. Sender and recipient information, goods description, quantity, and commercial references enable risk assessment and channeling to the appropriate path. Postal systems transmit this data in advance, then enrich the file with arrival and presentation events to authorities.

Declarative forms affixed to the shipment and electronic messages must describe the goods in sufficient detail for the application of import rules. Designated operators then coordinate the collection of any additional documents and the collection of duties and taxes when required by the destination country's regulations.

Service quality monitoring

Service quality is measured using common indicators on timeliness, flow integrity, data completeness, and claim satisfaction. Measurement programs and audit frameworks allow performance tracking, bottleneck identification, and the dissemination of best practices among operators. The availability of reliable and correctly sequenced tracking events is a central lever for continuous improvement.

Security and risk management

The security system relies on the prevention of prohibited shipments, control of dangerous goods, and detection of illicit content. Systematic data exchange, traceability of responsibility transfers, and actor authentication contribute to risk management. Operators apply secure sorting, controlled routing, and incident management procedures, with recovery scenarios in case of major disruptions.

Interoperability with carriers

Postal dispatches are frequently handled by third-party carriers. The UPU specifies messages to notify handover, acceptance, cargo, and return of units, to align physical reality with data. The goal is to avoid information breaks, improve predictability, and offer the final recipient continuous visibility despite the multiplicity of actors.

Programs and collaborations within the UPU

Beyond the legal framework, the UPU hosts operational programs that promote process harmonization, team training, and tool sharing. Technical communities develop implementation guides, message manuals, and testing procedures to support operators in compliance and performance optimization.

Exception and claim management

Exception handling must be documented and traceable. Operators exchange inquiry messages to locate an item, verify a transfer of responsibility, clarify a customs status, or organize a reshipment. Responses rely on event history, handling scans, and loading unit records. Response times and modalities are governed by common rules to ensure effective and fair resolution.

Proof of delivery and shipment tracking

Some services require proof of delivery. In this case, the origin and destination operators apply additional milestones related to signature, chain of custody security, and recipient or agent identity verification. Tracking events include attempt, notice, re-presentation, pending, and actual delivery, to provide complete traceability.

Standardized labeling and optical reading

Shipping labels are designed to withstand the physical constraints of transport while ensuring reliable reading by sorting systems. The barcode associated with the S10 number is the indexing key. Standardized information areas indicate the origin operator, internal references, and handling instructions. Clear printing, sufficient contrast, and consistent positioning are required to limit non-readings and sorting errors.

Digital transformation of the postal sector

The growth of online commerce has reinforced the UPU's role in standardizing data exchanges. Sending complete information in advance, validating message quality, aligning with customs requirements, and disseminating events in near real-time are priorities. The goal is to make postal transport more predictable and transparent, especially for merchant items.

Tracking terminology and logistics events

The tracking statuses observed by recipients reflect standardized events. They describe admission, movements between facilities, handover to a carrier, arrival in the destination country, presentation to authorities, delivery, and closure. Exception events document unsuccessful attempts, information requests, redirections, returns, and declared losses. This harmonized terminology allows operators to provide clear and comparable information, regardless of the country.

Use of standardized tracking

When the origin operator records a scan, the information is shared with the destination partner and feeds the consultation interfaces. Upon arrival, exchange facilities confirm receipt of dispatches and then publish events at the item level. Customs authorities can trigger dedicated milestones related to presentation, examination, release, or a request for documents. Events associated with delivery provide confirmation of passage, pending, or delivery, with useful details for the recipient.

Alignment and continuous improvement

Standardization is not enough if not accompanied by audits, feedback, and action plans. Operators use status analysis to identify areas of variability, measure scan completeness, reduce latency between events, and ensure reliable transfers of responsibility. The dissemination of guides and best practices helps standardize journeys and raise the service level in countries where infrastructures are rapidly evolving.
