Australian Business Numbers (ABNs)
Australian Business Numbers (ABNs) are unique identifying numbers useful for government in validating a business' identity. There is no requirement under the Act for an applicant to hold and supply an ABN. However if an ABN is supplied it must correspond on the Australian Business Register (ABR) to the legal name provided on the application. Notifications of ABN cancellations should be verified by a check of the ABR. If an applicant advises that a supplied and current ABN no longer applies to an electrical contracting business verifying evidence, such as a statutory declaration or written confirmation from an accountant, must be provided.
