Author identifiers

Your unique author ID will be with you throughout your research career and is used to:

  • avoid ambiguity and confusion over authorship and, thus, dispersion of the scientific output produced by the same author.
  • improve  and guarantee connection between the existing scientific output retrieval, collection and indexing systems and, thus, link referenced research activities in different information systems.
  • improve communication with the scientific community (submission of articles to publishers and documents to institutional repositories, etc.).
  • be able to take part in internal, national and international calls for grants.


The ORCID ID unique identifier allows every researcher to be identified unequivocally.

Recommendations on how to use ORCID

We recommend that researchers obtain an ORCID ID and include it in the signature of their publications.

It is linked to a large number of leading databases, publishers, and institutes and agencies for research funding and accreditation, both to reference publications and to export information to the CVs researchers keep in ORCID.

To get the most out of your ORCID ID, we recommend:

  • Including the ORCID ID in GIR.
  • Including the ORCID ID in your signature and personal webpages.
  • Including the ORCID ID in submissions to publishers.
  • Including the ORCID ID in calls and submissions for accreditation and grants.
How to get an ORCID ID.
Add your ORCID ID to GIR.

Other author identifiers

As publications are indexed in scientific production databases, authors are assigned other IDs that these databases generate automatically. 

ORCID ID is linked to other current author identification systems, such as:

  • ResearcherID, an identifier that can be created by any author who is registered and has access to the WoS database and who has articles indexed in it.
  • Scopus Author Identifier, which is created in the Scopus database once an article is indexed there.
  • My Citations, the identifier given by Google Scholar. To view your ID visit your Google Scholar Citations profile page.
