ORCID (Open Researcher and Contributor ID) is a nonprofit organization that provides a free registry of unique persistent identifiers (PIDs) along with a system of linking research activities to these identifiers. ORCID identifiers (also known as ORCID iDs) are unique to each researcher and can be used throughout their careers.
The format for ORCID iDs is an https URI with a 16-digit number that looks something like this: https://orcid.org/0000-0001-2345-6789. These iDs can be attached to many scholarly works, such as journal articles, citations, grants, patents, and data sets, which helps distinguish your work from materials created by other people with the similar names.
