ORCID is an Open Research and Contributor Identifier that has been developed for researchers and provides them with a unique 16-digit identifier for life. A researchers ORCID is owned by them and follows them through their career to new organisations, across disciplines and globally. It is free to all researchers and helps them to distinguish their research work and activities from others. To put it simply, by having an ORCID ID no two researchers with a similar name can ever be mistaken as the same person.



A RAiD (Research Activity Identifier) is a unique and persistent digital identifier for research activities. It connects institutions, people and resources associated with a research activity. RAID complements the GRID (Global Research Identifier Database) identifier for research organisations and the ORCID identifier for researchers.
