The Research Centre For Islamic History, Art and Culture – RCIHAC was so difficult to pronounce and remember, the OIC took a decision to change it into IRCICA which means I – Istanbul or international, R – Research, C – Centre, I – Islamic, C – Culture, and A – Arts. Due to its common usage and scope, the organisation was to be identified with this rare abbreviation and it was adopted as the official abbreviation of the organisation than being known as RCIHAC.
