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: https://orcid.org/0000-0002-3843-3472
Individuals will be able to register for an ORCID identifier at launch in October.
