ORCID ID: A Digital Persistent Identifier
A digital persistent identifier (DPI) is a unique number that represents an individual researcher. ORCiD is an independent organization that maintains a DPI registry of ORCID iDs. Both the National Institutes of Health (NIH) and the National Science Foundation (NSF) have selected ORCID as their DPI provider to fulfill NSPM-33 requirements.
Northwestern strongly recommends researchers sign up for an ORCiD ID so your research output
can be unambiguously associated to you as an individual.
