What is an LEI number and why Australian banks rely on it

The Legal Entity Identifier (LEI) is a globally recognised identification code used to uniquely identify legal entities involved in financial transactions. In Australia, the LEI number plays an increasingly important role in the banking sector, particularly for businesses opening or maintaining corporate bank accounts.

Australian banks operate under robust regulatory oversight, including requirements related to anti-money laundering (AML), counter-terrorism financing (CTF), and international financial transparency. The LEI number provides a standardised way to identify companies, enabling banks to verify corporate structures, assess risk exposure, and meet domestic and international reporting obligations, especially where cross-border activity is involved.

LEI number requirements when opening a business bank account in Australia

When opening a business bank account in Australia, banks may request an LEI number depending on the nature of the company and its financial activities. This is particularly common for companies engaged in securities trading, investment management, derivatives transactions, or international payments.

The use of an LEI number helps banks streamline due diligence processes and maintain accurate records of corporate clients. It also facilitates data consistency across financial institutions and regulators, reducing complexity when businesses interact with multiple banks or operate across jurisdictions.
