An ORCID iD is a permanent numeric identifier that you own and control, which provides a way to distinguish yourself uniquely from other researchers and scholars. ORCID iDs are often used in systems and platforms from grant applications to manuscript submissions, and are increasingly required by funders, publishers, data repositories, and other research workflows.
If you do not have your own ORCID iD yet, you can easily create one from the ORCID website.
Here is how you then link your ORCID iD to your account on the CITI platform.
