I have an account long ago with ORCID but still couldn't find a substantial evidence to justify the significance of its existence. I stand to be corrected if you have a different view.
Hi Chukwuebuka, in Mexico the core are in the interoperability of institutional repositories because the ORCID its the link for author and his publications. This is real for other countries, furthermore some universities used it for management in management process related to teachers.
