ORCID (Open Researcher and Contributor ID) is an international digital researcher identifier that identifies researchers and helps them stand out from other researchers. ORCID is perhaps the most widely used way of identifying a researcher and linking them into their output. There are already around 4 million ORCIDs worldwide. As a persistent identifier for researchers, it is widely used in numerous information systems and reference databases. ORCIDs can be used to link to publications, affiliations, grants, etc. Some scientific journals now ask for the ORCID of their authors.
