A legal entity identifier (lei) registration is a unique 20-character alphanumeric code required for all legal entities engaging in financial transactions. Whether you're a company, trust, partnership, or any organization dealing in securities, derivatives, or FX transactions, an LEI is essential for regulatory compliance and global recognition. LEI adheres to a standardised universal format recognised worldwide. This code adheres to the ISO 17442 standard developed by the International Organization for Standardization (ISO).
