Organizations in ORCID (Ringgold identifiers)

About organization identifiers

Users may include employment and education affiliations in their ORCID records. Affiliations must include an institution's name and address but should also include a unique identifier to disambiguate the institution. Currently, ORCID uses Ringgold organization identifiers to generate a pick-list of organizations. Ringgold is a registration agency for ISNI, and the Ringgold database will soon include crosswalked ISNI organizational identifiers.

Affiliations selected from the pick-list in the ORCID interface are linked with a Ringgold identifier automatically. Affiliations added via the API should use the <disambigated-organization> field to include the Ringgold identifier. In each case, ORCID recommends that users choose the parent organization (and not the division or department) as the affiliation. Department and title information may be provided in a separate field.

(NOTE: Developers using the ORCID API for affiliations should use XSD Version 1.2_rc1 or higher. See the XSD Readme file for more information.)

Ringgold provides a free search (registration is required) for looking up identifiers at For the best results, one should use the full name of the institution they seek, rather than abbreviations or acronyms. The main institution name will be recorded in its native language. Member organizations who need to locate multiple Ringgold identifiers should contact us for more information.
