An ORCID is a code to identify someone who writes academic articles. ORCID stands for Open Researcher and Contributor ID. Each person can have their own ORCID. ORCIDs make it easy to know which articles someone has written, even if they change their name. They also helps tell who has written which articles, if there is more than one writer with the same name. ORCID was started on 16 October 2012.
