The Research Institute of Posts and Telecommunications tradition has been maintained for over thirty years in Slovakia. The Institute was founded in 1976 as a branch of the Federal PTT Research Institute in Prague. At the very beginning, the branch Institute was tasked with selected problems in the area of telecommunications, radio communications and economic statements.
Another branch of the PTT Research Institute was established few years later in Žilina in 1981 with activities focused on post, post transportation, and related economic studies.
Since January 1st 1993, the Research Institute of Posts and Telecommunications in Banská Bystrica became an independent economic and legal entity with its branch office in Žilina. Progressive development and team building within a broad scope of professional competence were important during the formation of the independent research institute.
In 2002, the branch office in Žilina was separated and transformed into the administrative authority - The Postal Regulatory Office of the Slovak Republic, which exercises the regulation over the postal services market.
In 2004 the modification of VUS legal form took place and the institute was transformed to non-profit organisation, which founders has been the Ministry of Transport, Posts and Telecommunications of the Slovak Republic (now the Ministry of Transport, Construction and Regional Development of the Slovak Republic) and employees of VUS. Presently, VUS performs the mission of leading research institute for electronic communications and postal sector.
