ORCID iDs are persistent digital identifiers for individual researchers. Their primary purpose is to unambiguously and definitively link them with their scholarly work products. ORCID iDs are assigned, managed and maintained by the ORCID organization. Values MUST be valid ORCID identifiers in the ORCID-preferred URL representation. Each value represents an ORCID identifier registered with ORCID.org as belonging to the principal.

The ORCID iD is a URI with a 16-digit number that is compatible with the ISO Standard (ISO 27729), also known as the International Standard Name Identifier (ISNI). Initially ORCID iDs will be randomly assigned by the ORCID Registry from a block of numbers that will not conflict with ISNI-formatted numbers assigned in other ways. ORCID iDs always need all 16-digits; they can not be shortened to remove leading zeros if they exist.

Below are some example ORCID iDs expressed in the proper format.
