How to Find your ABN: Your Ultimate Guide

As Seen On

Ah, the Australian Business Number (ABN). It’s as essential to your business as Vegemite is to an Aussie breakfast. But what happens when you misplace it? Fear not; this comprehensive guide will show you how to find your ABN and why it’s as important as a good flat white on a Monday morning.

Guide To Find Your Abn.

The Importance of Your ABN

Your ABN is your business’s key identifier, much like your name is to you. It’s an 11-digit registration number used to identify businesses in Australia. You need an ABN to operate legally, whether you’re a sole trader, partnership, or company.

Think of your ABN as the business equivalent of a passport. It’s your ticket to interacting with other businesses and government departments, particularly for tax purposes. Lose it, and you might find yourself in a pickle. But don’t worry; finding your ABN is easier than finding a good parking spot in Sydney.

How to Find Your ABN:

To find an Australian Business Number (ABN), you can use the ABN Lookup service provided by the Australian Business Register (ABR). Here are the steps to find an ABN:

  • Go to the ABN Lookup website at
  • Use the search box at the top of every page to search by ABN/ACN or name.
  • You can use the advanced search option with extra filters such as state, postcode, tax concessions, and deductible gift recipient status for a more refined search.
  • If you are searching for your own ABN and know your business name, enter it into the search field.
  • If your ABN does not appear, you may need to contact the ABR to retrieve and manually update your ABN information.

Remember, it is important to keep your ABN details up-to-date, and you can update your ABN details at

Also, your ABN is usually included on all official documents. So, check your tax invoices or other business documents. It might be hiding there, like a kangaroo in the bush.

The Consequences of Not Displaying Your ABN Properly:

The consequences of not displaying your Australian Business Number (ABN) properly can be quite severe, impacting your business’s legal standing and financial health. Here’s what you need to know to avoid falling into the ABN abyss:

  1. Lost Revenue: If you fail to quote an ABN on your invoices, the payer must withhold 46.5% of the payment for tax purposes, a process known as “no ABN withholding.”. It can significantly reduce your cash flow, much like a leak in a dam wall can affect water levels.
  2. Jail Time: Using an ABN not issued to you by the Australian Taxation Office (ATO) or using a fake ABN is a serious offence. It can result in up to 2 years of imprisonment, especially if associated with black market activities. It is not a situation where you want to test the waters.
  3. Hefty Fines: In addition to potential jail time, incorrect use of an ABN can lead to substantial fines. The ATO takes the misuse of ABNs very seriously, and penalties reflect the gravity of the offence. It’s like playing with fire during a total fire ban – not a wise decision.

To avoid these penalties, ensure your ABN is correctly displayed on all formal documents, such as invoices and letterheads. If you’re unsure about your ABN or need to find it, the ABN Lookup tool provided by the Australian Business Register is the go-to resource. It’s a straightforward process: just enter your business name, and voilà, your ABN should appear. You may need to contact the ABR to retrieve and update your information if it doesn’t.

If your ABN has been cancelled due to inactivity, you can reactivate it by reapplying online. If your business structure changes, you might receive a new ABN; otherwise, your previous ABN should become active again.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
