Sources & method
Register entries come from the public registers of financial regulators, standardised into one taxonomy. LEIs are matched through GLEIF, and a BIC is linked only through a shared LEI.
An institution missing from these registers is not necessarily unregulated.
Register entries are not matched against the OFAC or EU sanctions lists. Where the legal entity also holds a BIC, the matches for that BIC are on its page. Always screen against the official lists.
An institution is one entry in the directory: a BIC8 in Swift’s directory, or a firm on a tracked register that holds no BIC. Licences held by an institution with a BIC are shown on its page.

Assess the financial crime risk behind a licence
A licence records what an institution is authorised to do; it does not assess it. The Elucidate FinCrime Index (EFI) is an independent score of the financial crime risk of banks and payment institutions.
