UPU tracking provides a standardized system for tracking packages across national postal operators. By integrating postal services globally, UPU tracking ensures that packages sent from one country can be reliably traced through multiple postal systems until delivery.
The Universal Postal Union (UPU) is a specialized agency of the United Nations that coordinates international postal services worldwide. Understanding UPU tracking is crucial for global shippers, retailers, and consumers who rely on secure and timely deliveries. This guide covers everything you need to know about UPU tracking and how to leverage it for your international shipments.
Tips for Tracking UPU Packages
To maximize the benefits of UPU tracking, consider these practical tips:
Check the origin: Determine the postal service of origin, as tracking updates usually start there.
Use official platforms: Always track through UPU's or the origin postal operator’s official portals to get accurate updates.
Understand time zones: International deliveries involve different time zones, so expect delays in tracking updates during off-peak hours.
Follow status codes: Pay attention to status codes such as “Acceptance,” “Dispatch,” “In Transit,” and “Delivered” for real-time updates.
How to Identify a UPU Tracking Number
A UPU tracking number is typically a unique alphanumeric code assigned by the originating postal service. These numbers vary slightly depending on the service used (e.g., EMS, Registered Mail).
UPU Tracking Number Format
UPU tracking numbers usually follow this standard UPU S10 format:
Two letters + nine digits + two letters
For example: EE123456789CN
The first two letters denote the mail class (e.g., “EE” for Express Mail).
The nine digits are the unique package identifier.
The final two letters represent the country of origin.
UPU Tracking Status Guide
Here’s what the typical status updates mean:
Acceptance: The package has been received by the postal service.
Dispatch: The package has been sent to the destination country.
In Transit: The package is on its way, with tracking updates depending on the postal network.
Out for Delivery: The package is with the final delivery agent.
Delivered: The package has been successfully delivered to the recipient.
