What is a Persistent Digital Identifier?

A persistent digital identifier (PDI) or permanent identifier is a univocal way to identify a researcher, for example in a database or in an institutional repository.

You should create a persistent digital identifier:

  • to avoid confusion of names,
  • to associate your publications with your profile,
  • to manage your publication list,
  • to use it as a promotion tool in order to make your research outputs more visible,
  • to access the metrics of your publications,
  • to save time by not having to enter information multiple times. (Possibility to extract your references),
  • to ensure compliance with certain research granting agencies/publishers requirements


ORCID (Open Researcher and Contributor ID) is an non-profit organisation (independent from publishers or databases).

It provides a free unique persistent digital identifier (PDI).

Keep in mind:

  • It is free and available to any researcher in any discipline.
  • It can be used by publishers, universities, repositories, research societies, funding agencies, etc.
  • ORCID users can manage their own visibility settings.
  • You can link your ORCID ID to other IDs like Scopus Author IDResearcherID on Publons, etc.
  • ORCID does not offer metrics but you can connect your ID to Kudos and ImpactStory to generate your personal metrics profile.
