ORCID (Open Researcher and Contributor ID) is a unique, persistent identifier assigned to researchers and scholars. It helps to distinguish individuals from others with similar names and ensures that their work (publications, grants, and other contributions) is accurately attributed to them. ORCID provides a digital identifier that researchers can use across platforms, ensuring consistency in how they are credited for their research and scholarly activities. Many journals, funding agencies, and institutions now require or encourage using an ORCID iD.
