The original company name was "Girozentrale der österreichischen Genossenschaften". In 1939, after the German annexation of Austria, the new German owners changed the name to "Genossenschaftliche Zentralbank der Ostmark Aktiengesellschaft", and then in 1942 to "Genossenschaftliche Zentralbank Wien Aktiengesellschaft". From 1953 on, the new name was "Genossenschaftliche Zentralbank Aktiengesellschaft", with the abbreviation GZB also being used for the company. Since 1989, the bank has been named "Raiffeisen Zentralbank Österreich Aktiengesellschaft", abbreviated as RZB.
