An ORCID (Open Researcher and Contributor IDentifier), or ORCiD, is a unique, persistent 16-character identifier that's assigned to you when you register at https://orcid.org. It's free to register and it's portable--your iD is not affiliated with a specific institution. The identifier serves as a mechanism by which you may collect your digital scholarship and connect with other systems to maximize workflows and efficiently disseminate your scholarship.
