Proof of Union Status (PoUS) System

Electronic PoUS system for T2L / T2LF and Customs Goods Manifest (CGM)

T2L and T2LF applications must be submitted electronically through the Proof of Union Status (PoUS) system.

From 15 August 2025 CGM for PoUS must also be submitted through the PoUS system.

You can access the PoUS system through the European Union (EU) Trader Portal.

To lodge a T2L / T2LF / CGM request on the portal:

you must have a Revenue Online Service (ROS) digital certificate. You will find information about obtaining a ROS certificate in About ROS.
you must have an Economic Operator Registration and Identification (EORI) number and be registered for Customs and Excise (C&E) on ROS
and
you must be authenticated in the trader portal. This is handled by the Uniform User Management & Digital Signature (UUM&DS) system together with ROS. You can use the UUM&DS to assign responsibility for customs applications and authorisations (delegation) to your customs representative.

You will find further information about how to create and manage these roles in Access Management through UUM&DS.

The EU Commission have developed the Proof of Union Status system eLearning Module for economic operators.

Further information on the electronic PoUS system can be found in eCustoms Notification 29/2023.
