Identifiers
Resolve a ticker, LEI, ISIN, FIGI or MIC to a structured entity with its knowledge-graph context — the connective tissue open financial data is missing.

Validator — check any code's checksum
Paste a LEI, ISIN, CUSIP, SEDOL, FIGI or MIC. Validation runs in your browser: format plus the standard's own check digit (ISO 7064 MOD 97-10 for LEI, Luhn-style modulus 10 for ISIN, weighted sums for CUSIP, SEDOL and FIGI). Nothing is sent to the server.
JSONCSV No key, CORS enabled — paste any of these straight into a notebook.

Legal entity
20-char ISO 17442 code from GLEIF (open, CC0). Answers "which company is this, legally".
Security
12-char ISO 6166 code identifying the security across venues. Check digits validated here.
Open instrument id
OpenFIGI share-class FIGI — open, free, venue-independent. The open alternative to licensed codes.
Coverage — 121 companies
Coverage counts and worked examples on the identifier pages are computed from our own covered set (seed-0.7 · marketcap-1 · 2026-08-30) — they describe this dataset, not the standard’s global coverage. Sources: LEI from the GLEIF API (CC0), matched by legal name and jurisdiction, then hand-audited. ISINs from public primary listings — except where a foreign issuer is carried here through its US ADR, in which case the ADR ISIN is shown and the row is marked ADR. ISO 6166 check digit validated; null where we are not certain (no guessing). FIGIs from the OpenFIGI API, names cross-checked against the company. seed-0.7 · marketcap-1 · 2026-08-30. CUSIP/SEDOL are licensed identifiers — referenced conceptually on Standards, never republished.
