A ROR ID is a free, persistent identifier for a research organization — issued by the Research Organization Registry (ROR) in the form https://ror.org/0xxxxxxxx. This guide is the practical companion to CASRAI’s ROR ID dictionary entry: it covers why an institution would want one, who is actually eligible to register, and the exact steps to request and start using a ROR ID once you have it.
What a ROR ID is, briefly
ROR launched in January 2019 as a free, community-governed registry, built collaboratively by the California Digital Library, Crossref, and DataCite, with an initial data seed donated by Digital Science from its GRID database (retired in 2022). Each ROR record carries an organization’s canonical name, name variants and multilingual labels, country, geographic coordinates, organization type, and relationships to parent, child, and related organizations, plus crosswalks to identifiers like ISNI and Wikidata. See the ROR ID dictionary entry for the full operational definition, and ROR vs. GRID if you’re trying to understand how ROR relates to the legacy database it succeeded.
A ROR ID identifies the organization itself — not a person (that’s ORCID), not a specific research output (that’s a DOI), and not a department or individual research group within a larger institution, which generally falls outside ROR’s registration scope (see “Who can register,” below).
Why funders, publishers, and research systems increasingly expect a ROR ID
The problem ROR solves is disambiguation. Institution names in research metadata are inconsistently written — abbreviated, translated, merged with a parent system’s name, or simply misspelled — which makes it hard for any downstream system to reliably answer a basic question like “how many funded projects, publications, or datasets is this university actually associated with?” A stable, resolvable identifier lets that question be answered by machine matching instead of fuzzy name-string comparison.
That’s why ROR has been built into core scholarly infrastructure rather than staying a standalone lookup tool:
- ORCID uses ROR as the default identifier for organization affiliations added to an ORCID record — when a researcher adds an employment, education, or service entry to their ORCID iD, the organization is expected to resolve to a ROR ID rather than a free-text name.
- Crossref and DataCite, which are themselves ROR’s co-operators, support ROR IDs directly in DOI metadata for author affiliations and funder attribution, making it possible to query “everything this institution funded or published” across both registries using one stable key.
- Publishers, repositories, and CRIS systems are progressively integrating ROR lookups into submission and metadata-entry workflows, replacing free-text institution fields with a ROR-backed autocomplete, precisely because it removes the disambiguation problem at the point of data entry rather than trying to clean it up afterward.
The pace and specifics of funder and publisher adoption continue to evolve, so don’t assume any single funder’s submission system requires a ROR ID without checking that funder’s current guidance directly — but the direction of travel across scholarly infrastructure is consistently toward ROR as the disambiguation layer, the same role ORCID plays for individual researchers.
Who can register an organization with ROR
ROR’s registry is broad but not unlimited. Per ROR’s own guidance, in-scope organizations are independent, enduring entities involved in producing or sponsoring research — universities, research institutes, hospitals, funders, publishers, government agencies, and similar bodies. Out of scope, generally: individual university departments, company divisions, and single-person organizations, which are expected to be represented through their parent organization’s ROR record instead.
Before requesting a new record, ROR’s own advice is to check three things first:
- Search the registry at ror.org to confirm the organization doesn’t already have a ROR ID — the registry holds well over 100,000 organizations already, so a surprising number of institutions (including smaller or regional ones) turn out to already be covered.
- Confirm scope eligibility against the criteria above — an independent, enduring, research-active organization with its own stable web presence and identifiable mission.
- Collect evidence: links to real research outputs — journal articles, datasets, grant records — where more than one independent source acknowledges the organization as an author affiliation, funder, or publisher. This is what ROR’s curation team actually checks the request against.
How to get a ROR ID for your institution
Registering is free — ROR IDs and their metadata are public domain, and there is no cost to request a new record or a change to an existing one. The process is community-curated rather than self-service issuance:
- Submit a request. The primary route is ROR’s public request form (linked from ror.org). If the form doesn’t work for your situation, requests can also be filed directly on GitHub using ROR’s issue templates for new organizations or record changes. Organizations needing to register many records at once (e.g., a national consortium or a funder onboarding many grantee institutions) can use ROR’s bulk-submission spreadsheet templates, submitted by email.
- Strengthen the request. Requests move faster when they include: multiple research outputs from independent sources showing the organization’s involvement; an organization name that matches how it actually appears in published research; evidence the organization functions independently of any parent entity (relevant for hospitals or institutes affiliated with a larger university system); and name variants, including multilingual labels where relevant.
- Wait for curation review. ROR’s curation team triages, validates, and publishes new and updated records in monthly (often more frequent) release files. Typical turnaround for a straightforward new-organization request is about 4-6 weeks. See ROR Curation for how CASRAI’s Dictionary describes this review process, and curated org record (ROR) for what the resulting record actually represents.
- Confirm the record once published. Search the registry again to confirm your organization’s new ROR ID and record are live, and check that the name, type, and location fields are correct before relying on it in your own systems.
One design point worth knowing before you register: the identifier itself is permanent once issued, but the metadata attached to it isn’t frozen. If your institution is renamed, restructured, merged, or split after registration, you request an update to the existing record through the same curation process — you don’t get a new ROR ID. Predecessor/successor relationships capture major organizational changes like mergers or splits without breaking the persistence of an identifier that’s already in use elsewhere.
Using a ROR ID once your institution has one
Getting the identifier is the easy part; the value comes from actually using it consistently:
- Point researchers to it for ORCID affiliations. When researchers at your institution add employment, education, or service entries to their ORCID iD, they should search for and select your organization’s ROR-backed record rather than typing the institution name as free text.
- Supply it to your publishing and repository workflows. Wherever a submission system, institutional repository, or CRIS platform offers a ROR-based affiliation lookup, use it instead of a free-text field — this is what actually produces the disambiguation benefit downstream, in Crossref and DataCite metadata for everything your institution’s researchers publish or deposit.
- Use the open data, not just the identifier. ROR publishes its full dataset (names, relationships, identifier crosswalks) as an openly licensed data dump and a public API, so institutional research-information systems can pull structured organizational data directly rather than maintaining a separate internal list.
- Keep the record current. If your institution’s name, location, or organizational relationships change, file a curation request rather than letting the public record drift out of date — other systems are relying on that record being accurate.
Frequently asked questions
Is there a cost to register for a ROR ID?
No. ROR IDs and their associated metadata are public domain and freely available, and there is no fee to request a new record or an update to an existing one.
Does every department or research center need its own ROR ID?
Generally no. ROR’s scope is independent, enduring organizations — university departments, labs, and centers that operate as part of a larger institution are typically represented through that parent institution’s existing ROR record rather than getting a separate one, though genuinely independent affiliated entities (an independent research institute or teaching hospital, for example) may qualify on their own.
How is a ROR ID different from an ORCID iD or a DOI?
They identify different things. An ORCID iD identifies an individual person; a DOI identifies a specific research output (an article, dataset, or preprint); a ROR ID identifies the organization — the university, funder, publisher, or research institute — that a person is affiliated with or that an output is attributed to.
Did ROR replace GRID?
Functionally, yes. ROR launched with a deduplicated snapshot of the GRID database as its initial dataset, and Digital Science retired GRID in 2022 in favor of ROR. See ROR vs. GRID for how the two relate and what changed for anyone still holding a legacy GRID identifier.
How long does it take to get a new ROR ID?
ROR publishes new and updated records in release files at least monthly, often more frequently, and a straightforward new-organization request typically takes about 4-6 weeks from submission to publication.
Who actually reviews and approves ROR registration requests?
ROR’s curation team, operating under ROR’s published curation policy, reviews each request against scope and evidence criteria before publishing it. See ROR Curation for how that review process works.
