Funder ID

The Crossref Funder Registry is a controlled vocabulary of approximately 30,000 funder names worldwide, structured as a hierarchical taxonomy (a funder, its sub-divisions, and aliases). Each funder is identified by a numeric ID under a DOI-style prefix (e.g. 10.13039/100000001 for the US National Science Foundation). Publishers and authors select funders from this list at submission so that the resulting Crossref deposit carries machine-readable funder information. ROR records increasingly carry the Funder ID crosswalk to enable joint queries.

In September 2023, Crossref announced the Open Funder Registry is transitioning into the Research Organization Registry (ROR): existing Funder IDs continue to be maintained and are auto-mapped to ROR IDs, but new funder-identification infrastructure is being built ROR-first. Publishers and systems adopting funder metadata going forward are encouraged to use ROR IDs, with the Funder ID crosswalk preserved for backward compatibility.
