A number of organizations and individuals have been asking: what does an ORCID identifier look like? The ORCID ID is a 16-digit number that is compatible with the ISO Standard (ISO 27729). ORCID IDs will be randomly assigned by the ORCID Registry and will be expressed as a URI. An example ORCID identifier would have the following structure: http://orcid.org/0000-0002-3843-3472. Individuals will be able to register for an ORCID identifier at launch in October.

ORCID aims to solve the name ambiguity problem in scholarly communications by creating a registry of persistent unique identifiers for individual researchers and an open and transparent linking mechanism between ORCID, other ID schemes, and research objects such as publications, grants, and patents.
