The University of Plymouth ran an ORCiD advocacy campaign in 2017 to increase researcher profiles in preparation for the REF. Through drop-in events, digital advertisements, and support from library staff, faculty heads, and bulletins, over 99% of University staff submitted to the REF connected their ORCiD profiles to the research management system. The campaign emphasized the importance of ORCiD compliance through hints that it would be mandated for the REF submission.
