ORCID: Introduction to ORCID


This guide introduces ORCID and shows you steps to work with your ORCID. For assistance, please contact the Scholarly Communication Librarian.

Why do researchers use ORCID?

More than five millions ORCID iDs have been issued since 2012, and the number is growing. The major benefits of using ORCID iDs include:

  • To help you distinguish yourself from others with similar names
  • To ensure your research outputs are associated with you
  • To improve the discoverability of your work 
  • To help you associate your contributions with your affiliation
  • To help you comply with publishers’ and funders’ policy that makes ORCID mandatory
  • To save your time, “enter once, re-use often”
  • To give you one persistent and unique identifier for your whole career

ORCID refers to Open Researcher and Contributor Identifier, which is a registry of identifiers for participants in research, scholarship, and innovation. The vision of ORCID is to uniquely identify all researchers and scholars, thus they can be reliably connected to all of their contributions. An ORCID iD has 16 unique digits (e.g. 0000-0001-2435-6789). It is free to register and use in research workflows such as manuscript and grant submission. When you use your ORCID iD in your research workflows, your ORCID iD becomes a metadata in your research activities, which ensure that you receive credit for all of your work regardless of your affiliations.

Who uses ORCID?

ORCID is a non-profit making organization and is increasingly supported by worldwide organizations in the research ecosystem.  When organizations collect researchers’ ORCD iDs in the research workflow, they can reliably connect research activities to the individual researchers. ORCID offers a robust digital infrastructure to support this collect and connect process and makes this process transparent and trustworthy. The types of organizations involved in the research ecosystem include:

  • Publishers
  • Funding organizations
  • Universities
  • Data repositories
  • Abstract and citation databases
  • Identifier registration agencies
  • Research and professional organizations

You may find the full list of organizations by accessing the ORCID member organizations.
