ORCID Researcher Identifier: What is ORCID?

Open Researcher and Contributors ID - persistent digital author identifier

ORCID mission

"ORCID aims to solve 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. These identifiers, and the relationships among them, can be linked to the researcher's output to enhance the scientific discovery process and to improve the efficiency of research funding and collaboration within the research community." Our Mission

What is ORCID?

Distinguish yourself!

Distinguish yourself with ORCID!

ORCID (Open Researcher & Contributor ID) is a registry of unique identifiers for researchers and scholars that is open, non-profit, transparent, mobile and community-based.

ORCID provides a persistent digital identifier that distinguishes you from every other contributor and supports automated linkages among all your professional activities.

ORCID provides two core functions:

  • a registry where you can obtain a unique identifier and manage a record of activities
  • APIs that support system-to system communication and authentication

The ORCID Registry is available free of charge to individuals, who may obtain an ORCID identifier, manage their record of activities, and search for others in the Registry.
