An ORCID is a code to identify someone who writes academic articles. ORCID stands for Open Researcher and Contributor ID.[1] Each person can have their own ORCID.[1][2] ORCIDs make it easy to know which articles someone has written, even if they change their name.[1] They also helps tell who has written which articles, if there is more than one writer with the same name.[1] ORCID was started on 16 October 2012.[3]

ORCIDs usually have four groups of four numbers. An example of a person with an ORCID is John Wilbanks. His ORCID is https://orcid.org/0000-0002-4510-0385.[4] That is also the web address of the page about him, on the ORCID website. His ORCID can also be written as "ORCID: 0000-0002-4510-0385".[5] Sometimes an ORCID has an "X" instead of a number at the end. An example of this is Nick Jennings's ORCID. His is https://orcid.org/0000-0003-0166-248X. The final number (or "X") is a check digit.
