Open Researcher and Contributor IDs (ORCID iDs) enable identification, linking and discovery between researchers. ORCID provides a registry where individuals may obtain a unique PID, which can be used in connection with their research and scholarly workflows.
The ORCID iD is for anyone involved in research, scholarship or innovation. ORCID’s mission is: "to enable transparent and trustworthy connections between researchers, their contributions, and affiliations by providing an identifier for individuals to use with their name as they engaged in research, scholarship and innovation activities".
An ORCID iD can be used throughout the research process, for example when a researcher writes a data management plan, deposits a dataset into a repository, or accesses a dataset for analysis purposes.
ORCID iDs are managed by a nonprofit organization by the same name and designed to serve individuals, research and scholarly organizations, data repositories and libraries, publishers, patent offices, service providers, etc.
ORCID iDs are designed for anyone who participates in research, scholarship, or innovation, and will serve as a persistent identifier throughout their career.
After registering for an ORCID iD a researcher can grant permission to the systems and platforms they use (such as their research institution or a publisher of one of their articles) to update their ORCID record, allowing for easy and error-free sharing and re-use of the information. Ideally, this will save time for researchers as well as make relevant connections between works and organizations.
