Part of the Australia LEI knowledge hub — back to the Australia pillar.
An LEI is different from an Australian Business Number (ABN) or Australian Company Number (ACN). An ABN identifies a business in Australia, while an ACN identifies a registered company. A Legal Entity Identifier (LEI) provides a globally recognised identifier for eligible legal entities participating in financial activities.
Your ASIC (ABN/ACN) registration number proves the entity exists in Australia. The LEI is the globally-recognised ISO 17442 identifier used in financial reporting and counterparty checks worldwide.
The registration number is for domestic legal existence; the LEI is for financial-market identity. They complement, not replace, each other.
The LEI's Level 1 reference data records the ASIC (ABN/ACN) registration number, linking your global identity to your local registration.
