What is an LEI?
A Legal Entity Identifier (LEI) is a unique 20-character code used internationally to identify legal entities participating in financial transactions. The LEI system was introduced to improve transparency in global financial markets, making it easier to track parties involved in transactions and reduce the risk of fraud.
Key points about LEI:
- Global identifier: Recognised worldwide, not just in Australia.
- Required for financial transactions: Especially for entities dealing in securities, derivatives, and other regulated financial instruments.
- Issued by accredited providers: In Australia, you can obtain an LEI through trusted service providers such as LEI Service Australia.
What is an ABN?
An Australian Business Number (ABN) is an 11-digit identifier issued by the Australian Business Register (ABR) and managed by the Australian Taxation Office (ATO). It’s essential for any business or entity carrying out enterprise activities in Australia.
Key points about ABN:
- National identifier: Unique to Australia.
- Required for tax and GST purposes: Needed to register for GST, claim tax credits, and issue invoices.
- Used by all types of businesses: Sole traders, partnerships, companies, trusts, and non-profits.
What is an ACN?
An Australian Company Number (ACN) is a unique 9-digit number issued by the Australian Securities and Investments Commission (ASIC) to every company registered in Australia. It’s used to identify companies and is required to be displayed on all company documents.
Key points about ACN:
- Company-specific: Only issued to companies, not sole traders or partnerships.
- Legal requirement: Must be displayed on official documents, invoices, and company correspondence.
- Issued by ASIC: Automatically assigned when a company is registered.

Do You Need All Three?
Not every business needs all three identifiers. Here’s a quick guide:
- Sole traders and partnerships: Usually only need an ABN.
- Companies: Need both an ACN and an ABN. If involved in financial transactions, they may also require an LEI.
- Trusts and funds: May need an ABN and, if participating in financial markets, an LEI.
Why Are These Identifiers Important?
Having the correct identifiers ensures your business is compliant with Australian laws and regulations. It also streamlines business operations, from invoicing and tax reporting to participating in global financial markets.
If your business needs to obtain an LEI quickly and easily, consider using a trusted provider like LEI Service Australia, which offers fast registration and renewal services.
Understanding the differences between LEI, ABN, and ACN helps you stay compliant and operate smoothly in Australia’s business environment. Make sure your business has the right identifiers for your activities and industry.
