ORCiD (Open Researcher and Contributor ID) is a persistent digital identifier that distinguishes you from every other researcher.
Do you have a common name? Have published some articles with your middle initial, some with your first initial, and others with your full name? Have you changed your name during your research career?
ORCID solves these problems and distinguishes you as a researcher.
ORCID works like a driver's license number or your Spartan ID#. It is your research fingerprint -- providing a number that uniquely identifies you and your research.
