ORCID is a unique personal number for researchers. ORCID is issued by an American non-profit organization and is used worldwide by publishers, repositories and institutions to uniquely identify researchers
By registering ORCID once and linking it directly to your institution ID via SURFconext, various services can automatically receive this number when you log in with your institution account. You will always be asked per service if you want to share your ORCID and you can undo this link at any time.
