In the area of postal services the Agency collaborates with several international organizations and institutions. It attends professional conferences on postal services and works together with European regulatory bodies. The Agency's experts actively participate in numerous international bodies. Below are a few of the most important international institutions.
EGRP
ERGP (European Regulators Group for Postal Services) is the European group of regulatory bodies for postal services, funded by the European Commission at the end of 2010. The founding meeting was on 1 December 2010.
The Decision of the European Commission on establishing the European Regulators Group for Postal Services was published in the Official Journal of the European Union - 2010/C217/07.
The legal foundation for establishing this body is in the Postal Directive 97/67/ES, which includes the requirement that member states must appoint one or more independent regulatory bodies in postal services. They must work towards the development of a single European postal market, which requires mutual cooperation and, consequently, the organization of a joint working body. Working groups have been set up within the EGRP, in which the Agency is also actively involved.
CERP
CERP, the European Committee for Postal Regulation, was reformed into two working groups since the foundation of the ERGP.
- WG UPU, the Universal Postal Union, and
- WG Policy.
UPU
UPU is the Universal Postal Union. The Agency participates in the activities of the international office of the Union by filling out questionnaires and preparing opinions, and takes part in discussions on the future of the sector at the international level.
In September 2025, the Agency participated in the Universal Postal Union Congress in Dubai, where it assisted the delegation of the Republic of Slovenia, which succeeded in electing the Republic of Slovenia to the Postal Operations Council and the Administrative Council, with the re-election of Slovenian Mr Marjan Osvald as Deputy Director of the Universal Postal Union.
CEN
CEN, the European Committee for Standardization hosts about 300 technical committees. One of them is TC331, which focuses on preparing standardized documents pertaining to postal activities.
