ORCID iD
Also called: ORCID
A persistent identifier for a researcher, solving the problem that names are neither unique nor stable.
An ORCID iD looks like 0000-0002-1825-0097 and belongs to a person for their career. It exists because author names collide, get transliterated inconsistently, and change — and because citation counts, funding records, and publication lists all break when they do.
ORCID iDs do not go in reference-list entries. They appear on the byline of your own papers, in submission systems, and in grant applications. Many publishers and funders now require one.
