After the distinctive iD icon, the ORCID iD consistently displays 16 digits. This unique numerical sequence is the core of the ORCID identifier, providing a persistent and unambiguous record for researchers.
Understanding the ORCID iD Structure
An ORCID iD (Open Researcher and Contributor ID) is a widely adopted, non-proprietary alphanumeric code that uniquely identifies academic authors and contributors. It addresses the challenge of distinguishing researchers with similar names and connects them to their various research activities and outputs. The visual representation of an ORCID iD is instantly recognizable by its green iD icon, immediately followed by its unique numerical identifier.
The 16-Digit ORCID Identifier
The numerical part of an ORCID iD is a 16-digit identifier, typically presented in four groups of four digits separated by hyphens. For example, a common format looks like XXXX-XXXX-XXXX-XXXX. This standardized 16-digit structure ensures global consistency and enables seamless integration across various research systems and platforms.
The full ORCID iD, including the protocol and domain, often appears as a URL, such as https://orcid.org/0000-0002-1825-0097. When displayed or shared in its common, shortened form, it always features the iD icon preceding this unique 16-digit sequence.
Why 16 Digits? The Purpose of ORCID
The specific 16-digit format is crucial for ORCID's mission to provide persistent and unique identifiers. These digits serve several vital functions in the academic and research ecosystem:
- Researcher Disambiguation: The primary goal is to distinguish between researchers, especially those with common names, ensuring credit is accurately assigned. Each 16-digit identifier is unique to one individual.
- Connecting Research Output: It links researchers to all their contributions, including publications, grants, datasets, peer reviews, and more, across different institutions and platforms.
- Streamlining Academic Workflows: By providing a consistent identifier, ORCID helps automate data exchange between research information systems, reducing the administrative burden on researchers and institutions.
- Portability: Unlike institutional IDs, an ORCID iD is portable and remains with a researcher throughout their career, regardless of changes in affiliation.
Visual Representation and Examples
The ORCID iD is designed for clarity and easy recognition. You will typically see it displayed as:
iD0000-0002-1825-0097iDhttps://orcid.org/0000-0002-1825-0097
The green iD icon acts as a visual cue, signifying the presence of a globally recognized researcher identifier, followed by the specific 16 digits that uniquely identify the individual.
Key Features of the ORCID iD
To further understand its significance, here's a summary of the ORCID iD's key characteristics:
