Part of the United States LEI knowledge hub — back to the United States pillar.
A BIC and an LEI are different identifiers. A BIC identifies a financial institution or business party within financial messaging, while an LEI identifies the underlying legal entity. The BIC-to-LEI Relationship File helps users cross-reference organizations that have both identifiers.
A BIC is used to identify institutions and business parties within financial messaging and reference data. An LEI is a unique 20-character identifier linked to public legal-entity information. When an organization has both identifiers, the BIC-to-LEI Relationship File can connect the records for reconciliation and entity-data management.
BIC-to-LEI mapping can help banks and other data users match messaging records with standardized legal-entity information. It may support data reconciliation, counterparty identification and risk-management processes. It does not replace KYC, beneficial-ownership checks or sanctions screening.
No. Many legal entities have an LEI but no BIC, while some financial institutions may hold both identifiers. The BIC-to-LEI Relationship File only cross-references entities for which a matching BIC and LEI relationship is available.
ISO 20022 supports structured party and organization-identification data. An LEI can be included where the relevant message definition and implementation support it. A BIC may also be used for messaging identification, but the two identifiers serve different purposes. Not every ISO 20022 or SWIFT message is required to contain an LEI.

ISO 20022 can support an LEI in structured organization-identification data. Whether it is used or required depends on the specific message, payment system and financial institution.
