What is the UPU and what regulations are changing?

September 2019

Who are The Universal Postal Union?
The Universal Postal Union was established in 1874 and is a United Nations agency, responsible for the coordination of all postal policies among its 192 member nations, in addition to the worldwide postal system. 

What are the changes?

  • Any international item containing goods must have a unique S10 barcode attached
  • Customs data must be declared electronically against the S10 barcode, where items contain goods. 

What items are effected?
This mandatory requirement being enforced by the UPU, must be declared for all untracked international items, which have an intrinsic value. This includes samples, e-commerce items and large letters and packets.

How are postal authorities responding to the change?
Electronic customs data is becoming standard practice, however there is a differing pace of adoption across the globe. This change in adoption is based on each country's postal authority and their access to systems, technology and implementation of new processes.

Get Started

One of the big benefits of our new International Insight system is that it will help sellers ensure their international shipments meet all the requirements for electronic customs pre-advice, barcoding which should help prevent any delays. What’s more, with access to more accurate, item-specific information on every shipment, sellers will be able to answer customers’ queries more efficiently. It certainly makes life easier, saving a lot of time on administration and increasing visibility on both part-tracked and fully-tracked services so that everything runs smoothly from collection right through to delivery.
