Welcome Print Page


The international exponential growth of information & research databases has resulted in the problem of scholars and authors having the same or similar names. The need to differentiate between these authors to avoid any confusion or `ambiguity about a researcher's identity’ is addressed by a unique identifier system.  Three of these options are the ORCHID ID, Research ID, and Scopus ID. This guide will serve to tell you the differences between the three and how to obtain and use your ID.


Differences between ORCHID, Researcher, and Scopus IDs




1. ORCID ID (Open Researcher and Contributor ID)

ORCID solves the name ambiguity problem in research and scholarly communications by creating a central registry of unique identifiers for individual researchers and an open and transparent linking mechanism between ORCID and other current researcher ID schemes.

  • It allows researchers to track their publications and other scholarly contributions
  • institutions to compile and update profiles of their faculty/researchers
  • research funding agencies to manage grant applications and grantee databases
  • publishers to maintain author records and sort manuscript submissions
  • repository administrators to handle deposits of research publications and datasets
  • ORCID IDs are issued out of sequence and do not provide any semantic information such as the country of origin of their holders. 
  • An ORCID ID can be linked to other author identifier services, e.g., Researcher ID, Scopus Author ID, RePEC, and INSPIRE. 


·ORCID is free

·Compatible with ISO Standard 27729

·an ORCID ID can be associated with an output in any article from any publisher, the identifier can be attached to datasets, equipment, media stories, experiments, patents and notebooks.


Thomson Reuters created Researcher ID specifically for their products.

  • Researcher ID integrates with Web of Science to provide impact metrics
  • Thomson Reuters is a founding member of ORCID
  • Researcher ID is ORCID compliant
  • Researcher ID is the primary place where Times Cited data in the Web of Science™ Core Collection appears, thus underscoring the importance of having both identifiers, and having them connected.

·  ORCID compliant

·  “added value” services such as citation analysis

·  Not free – accessible only with subscription to Web of Science

·  Even if a researcher has an existing ORCID through another resource, there is value it be linked to his/her Researcher ID profile for a proper trail of information.


3. Scopus Author ID

Linked to ORCID - the Scopus Author ID continues to add enhanced integration points while supporting the mission of ORCID.

  • Researchers  associate their Scopus Author Identifier to their ORCID and import papers from Scopus to his/her ORCID profile
  • Scopus Author ID is automatically assigned to all authors (not just those of Elsevier) and also ensures this information is accurately reflected in the various Scopus tools such as search and analytics (e.g. citation tracking, h-index etc.

·  Linked to ORCID

·  “added value” services such as citation analysis

·  Not free – available subject to subscription to SCOPUS
