If a researcher attempts to register for a new ORCID iD with an email address that is already associated with an ORCID iD, they will be prompted to sign into the existing record.
If they try to register with a different email address, but with the same name as other registrants, they will be asked to review existing records with that name, and to verify that they don't already have an ORCID record.
