Go to TPOP

Do you sell in a country other than your own? You might need an identification number (IDU)

Are you being asked for an IDU number to sell? Everything is explained in this article.

What is an IDU?

An IDU (Unique Identifier) is a number required in some countries to prove that the seller complies with local rules regarding recycling, packaging, or the environment.

This number is often linked to a system called Extended Producer Responsibility (REP / EPR).


Am I affected?

You are affected if:

  • You are the official seller (the one billing the end customer),

  • You sell packaged products to customers located in other countries,

  • And those countries require sellers to register.

Even if TPOP ships the products for you, you remain legally responsible.


Do I need to register in every country?

In most cases, yes.
Each country in the European Union (and beyond) has its own rules.
There is no unified system or single number valid everywhere.

You will generally need to:

  • Register with the official organization of the relevant country,

  • Obtain an identifier,

  • Declare it if requested by a marketplace or an authority.
