Under the Corporations Act 2001, every company in Australia has been issued with a unique, nine-digit number, an Australian Company Number (ACN), which must be shown on a range of documents. The purpose of the ACN is to ensure adequate identification of companies when transacting business. New companies are issued with numbers by the Australian Securities & Investments Commission (ASIC) upon registration.
The ACN is generated using an algorithm with the last digit being a check digit allowing the number to be verified.
A company's ACN should appear on all of its 'public documents' and 'eligible negotiable instruments' [s.153]. The items on which it should appear include:
If a company's name appears on two or more pages of a document or instrument, the ACN must be shown on the first of those pages following the company's name.
Where a number of separate companies are listed on a document (e.g., a letterhead) the ACN of each should appear and in such a way that makes clear the company to which each ACN relates.
While there are no specific requirements as to how an ACN should appear on a document, it should be clear, easily readable, and obvious as to the company to which it relates.
The ACN should be identified by the words 'Australian Company Number', or by the abbreviations 'ACN' or 'A.C.N.'.
The items on which the ACN is not required include:
? Packaging and labelling, including envelopes and transport documents;
? Advertisements which do not make a specific offer which is capable of being accepted (such as advertisements which only promote the company and its goods or services in general);Credit cards and credit card vouchers;Machine-generated receipts, including cash-register receipts;Business cards and 'with compliments' slips; andItems which are not documents (e.g., vehicles, television advertisements).
If your company has an Australian Business Number (ABN), you may use the ABN with your company's name in place of the ACN on company documents and negotiable instruments, provided that:
If your entity is a Trust, the Australian Business Number (ABN) of the Trust must be stated after the Trustee company name and ACN.
