LEI
ComplianceLEI (Legal Entity Identifier) is the 20-character ISO 17442 code that uniquely identifies legal entities in financial transactions, mandatory in most ISO 20022 messages.
The LEI is a global standard for identifying any legal entity participating in a financial transaction. It is structured as 20 alphanumeric characters: 4 characters for the LOU (Local Operating Unit that issued it), 14 characters for the entity identifier, and 2 check digits.
Under CBPR+ ISO 20022 mandates, LEIs are required in pacs.008 and pacs.009 messages wherever the originator or beneficiary is a legal entity (rather than a natural person). The G20 has pushed for mandatory LEI inclusion in all cross-border payments as part of the G20 Roadmap for Enhancing Cross-Border Payments.
For crypto businesses — exchanges, OTC desks, and remittance providers — obtaining a LEI is a prerequisite for operating as a counterparty in ISO 20022-compliant payment flows. Ripple, Stellar, and Quant all hold LEIs, as do their major institutional partners.
Crypto Relevance
LEI requirements in ISO 20022 messages are a compliance filter that institutional-grade crypto infrastructure must meet — Ripple and Stellar's institutional products all support LEI embedding in their payment message flows.
