An ORCID iD is a 16-digit Open Researcher and Contributor ID you own and control. It enables you to consolidate your research under one ID. You can also add research activities that are not represented in significant databases, as well as combine variations.
ORCID iD enables individuals and organisations to track research expertise globally without naming ambiguity.
Author name ambiguity means that the author name can't be used to reliably identify all scholarly authors, therefore making it impossible to unanimously associate with research outputs their authors.
