What is ORCID?

ORCID (Open Researcher and Contributor ID) is a persistent digital identifier system for researchers and scholars. It gives each person a unique 16-character iD that distinguishes them from every other researcher, even if they share the same name or publish under different name variants. Registration is free, and the iD can be linked to publications, datasets, affiliations, and other scholarly records across systems.

The problem ORCID solves

Academic databases, publishers, and funders all need to know which "J. Smith" wrote a given paper. Common names, name changes, transliteration differences, and inconsistent formatting make author disambiguation a persistent headache. ORCID addresses this by assigning a stable identifier that travels with the researcher across platforms.

Key consequences:

• Name ambiguity disappears. Two researchers named "Li Wei" have two different ORCID iDs.
• Identity persists across name changes. A researcher who marries, changes legal name, or alters transliteration keeps the same iD.
• Records connect automatically. When a publisher, repository, or funder collects your ORCID iD, your works can flow into your ORCID record without manual re-entry.

What an ORCID iD looks like

An ORCID iD is a 16-digit number formatted as four groups of four, for example: 0000-0002-1825-0097. The final character may be an "X" (a checksum value). It is expressed as a URI: https://orcid.org/0000-0002-1825-0097.

The iD itself is opaque — it carries no meaning about the person. All descriptive information (name, affiliations, works) lives in the associated ORCID record, which the researcher controls.

What you can link to an ORCID record

You can add records manually, import them from trusted sources (Crossref, DataCite, Scopus, institutional systems), or let authorized systems write to your record automatically.

Who runs ORCID

ORCID is an independent, non-profit organization governed by a board and supported by member organizations — including publishers, funders, universities, and research institutions. It is not owned by any single commercial entity. The registry is community-governed and the iD is designed to be interoperable across the scholarly ecosystem.

When ORCID is useful — and when it isn't

Useful when:

• You publish under a common name or have published under multiple name variants.
• You want your works to aggregate automatically across publishers and repositories.
• A journal, funder, or institution asks for an ORCID iD during submission or reporting.
• You want a single public profile that links your outputs.

Not a replacement for:

• A CV or institutional profile page (ORCID is a record, not a narrative).
• A bibliometric database (it does not compute citation counts or h-index).
• Authentication for every system (it is an identifier, not a universal login).

Getting started

1. Go to orcid.org and register with your name and email.
2. You receive a 16-character iD immediately.
3. Set your record visibility (public, trusted parties, or private) for each item.
4. Add works and affiliations manually or via import wizards.
5. Use your iD wherever publishers, funders, or repositories request it.

The registration and basic record are free. Some institutions and publishers integrate ORCID into their own systems, so you may be prompted to connect an existing iD rather than create a new one.
