I Lost My ABN, Where Can I Find My ABN?

Misplacing your Australian Business Number (ABN) can be stressful, especially when you need it for tax or business-related activities. Your ABN is a unique identifier issued by the Australian Business Register (ABR) and managed by the Australian Taxation Office (ATO). Fortunately, there are several ways to retrieve your ABN quickly and securely. This guide will walk you through the steps to find your ABN and keep it safe for the future.

Quick Reference Table: Steps to Find Your ABN

Step Action Requirements
1. Check ABR Website Use the ABN Lookup tool to search for your ABN. Business name or personal details (if a sole trader).
2. Review ATO Correspondence Look for your ABN in letters, tax returns, or BAS statements. Access to past ATO communications.
3. Check Internal Records Search through invoices, contracts, or registration documents. Business records (physical or digital).
4. Log Into MyGov Retrieve your ABN through the ATO section in MyGov. MyGov credentials linked to your business account.
5. Contact the ABR or ATO Call the ATO or ABR for assistance in locating your ABN. Proof of identity and registered business details.

1. Check the ABR Website

The easiest way to find your ABN is by using the ABN Lookup tool. This public database allows you to search for your ABN using your business name, trading name, or your personal name (if you’re a sole trader).

Steps to Search:

  1. Visit ABN Lookup.
  2. Enter your business name or personal name in the search bar.
  3. Locate your ABN in the search results.

Remember, the ABN Lookup tool only works for businesses with an active or cancelled ABN. If your ABN is inactive, it will still appear in the search.

2. Review ATO Correspondence

Your ABN is often included in official correspondence from the ATO. Check these documents:

  • Tax Returns: Your ABN will be listed in all business tax returns.
  • BAS Statements: Any lodged BAS forms will contain your ABN.
  • ATO Letters: General correspondence from the ATO often includes your ABN.

Pro Tip: Search your email inbox or physical mail for terms like “Australian Taxation Office” or “ABN” to locate these documents quickly.

3. Check Internal Business Records

If you’ve kept copies of your business registration documents, invoices, or contracts, your ABN may already be recorded there. Here are some places to check:

  • Registration Paperwork: Your ABN is listed on the documents you received when registering your business.
  • Invoices: Many businesses include their ABN on customer invoices.
  • Contracts: Business contracts often display the ABN for verification purposes.

Keeping these records organised can save time in the future when you need to retrieve your ABN.

4. Log Into MyGov

If you’ve linked your MyGov account to your business profile, you can easily retrieve your ABN through the ATO section.

Steps to Retrieve Your ABN:

  1. Go to MyGov.
  2. Log in with your credentials.
  3. Navigate to the ATO section to view your business details, including your ABN.

Not linked yet? Follow the instructions on MyGov to link your business profile for easier access in the future.

5. Contact the ABR or ATO

If you’ve tried all other methods and still can’t locate your ABN, contact the ABR or ATO directly. Here’s how:

  • ABR Contact: Call the ABR support line at 1300 139 226.
  • ATO Contact: Reach the ATO business line at 13 28 66.

Be prepared to provide proof of identity, such as your driver’s licence or passport, and registered business details like your business name or trading name.

How to Prevent Future Loss of ABN

To avoid misplacing your ABN again, take the following steps:

  • Secure Digital Storage: Save your ABN in a password-protected document or cloud storage service.
  • Backup Records: Keep both physical and digital copies of your business registration documents.
  • Use Accounting Software: Platforms like Xero or MYOB often store ABN details securely.
