The unique identification of organizations by means of PIDs is essential to make the research performance of institutions fully visible. This requires linking organizational identifiers to researchers and their research activities. There are various identifiers for organizations, the most prominent being the ROR ID, GRID, ISNI and, in German-speaking countries, the GND ID.

Permanent identifiers for funding information (Gepris or Crossref Funder Registry) and projects (RAiD) also fall into this category.
