The Universal Postal Union (UPU) is an international organisation acting as a UN agency and located in Bern, the capital of Switzerland; its members comprise the governments of participating countries. The UPU was founded in 1874 which makes it the second oldest international body in the world. The UPU has 192 members.
The UPU is the main body for improving global cooperation in the field of postal products and services. The organisation plays an advisory and mediating role, and also offers technical assistance where needed. The UPU sets the rules for international mail exchanges and parcel services, and also plays an increasing role in financial services volumes.
In September 2016, the 26th global postal congress was held in Istanbul, Turkey, where the strategy for 2017-2020 was adopted.
Estonia has been a member of the UPU since 1992. The Representation is mainly collaborating on UPU issues with the Ministry of Economic Affairs and Communications, as well as companies offering postal services.
