In the field of postal services, the Agency cooperates with various international organisations and institutions. It participates in professional conferences in the field of postal services and cooperates with European regulatory authorities. In many international bodies, its experts take an active part and engage in discussions. The most important international institutions are listed below.
EGRP
ERGP (European Regulators Group for Postal Services) is the European group of regulatory authorities for postal services, established by the European Commission at the end of 2010, and represents the common body of European postal regulators. The inaugural meeting of the group took place on 1 December 2010.
The Decision of the European Commission on establishing the European Group for Postal Services is published in the Official Journal of the European Union (2010/C 217/07).
The legal basis for the establishment of this body lies in Postal Directive 97/67/EC, which lays down the requirement that Member States must designate one or more independent regulatory authorities in the postal sector. These authorities must work towards the development of a single European postal market, which requires mutual cooperation and, consequently, the organisation of a common working body. Within the ERGP, working groups have been established in which the Agency also plays an active role.
CERP
CERP (European Committee for Postal Regulation), the European Committee for Postal Regulation, was reorganised into two working groups following the establishment of the ERGP:
WG UPU (Universal Postal Union) – Universal Postal Union, and
WG Policy.
UPU
UPU is the Universal Postal Union. The Agency participates in the activities of the International Bureau of the Union through questionnaires and the preparation of opinions, and takes part in discussions on the future of the sector at the international level.
In 2025, the Agency participated in the Congress of the Universal Postal Union in Dubai, where it assisted the delegation of the Republic of Slovenia, which secured the election of the Republic of Slovenia to the Postal Operations Council and to the Council of Administration, together with the re-election of Marjan Osvald of Slovenia as Deputy Director of the Universal Postal Union.
CEN
CEN is the European Committee for Standardization, within which around 300 technical committees operate. Among them is TC331, which deals with the preparation of standardisation documents relating to postal activities.
