Key takeaways
- Verify your business name availability and restrictions before registration by using ASIC's name checking tools and IP Australia's trademark search to avoid costly rejections and legal issues.
- Obtain an Australian Business Number (ABN) first, as it's required before you can register any business name through either the Business Registration Service or ASIC Connect.
- Register your business name if you trade under anything other than your exact personal name, including when adding descriptive words like "Plumbing" to your personal name.
- Choose between one-year registration ($45) or three-year registration ($104) based on your business planning timeline, and ensure you renew before expiration to maintain legal trading status.
What is a business name?
A business name is the official trading name that identifies your business to customers and government agencies. This name appears on all your legal documents, invoices, website, and signage, making it a crucial part of your business identity.
Business names can take several strategic approaches:
- Personal name: Jane Wells (simple and personal)
- Descriptive name: Morgan Adams Bookkeeping (clearly shows the service)
- Location-based name: Alice Springs Snake Removal (targets a local market)
- Creative name: Xero (memorable and brandable)
- Acronym name: Totally Awesome Plumbing Services (TAPS) (professional yet memorable)
As an example to another approach, ACME became a popular business name in the early days of alphabetised telephone directories. Businesses that started with an “A” often appeared closer to the front of the directory, which many saw as a way to suggest quality and stand out.
Whatever you come up with, your business name is part of your brand so it should reflect that. Make it memorable, easy to pronounce and spell, and preferably make it something that inspires you every day.
Do you have to register a business name?
You must register your business name unless it matches exactly with your personal name or an existing registered company name with ASIC.
When registration is required:
- Trading as anything other than your full legal name
- Adding descriptive words to your personal name
- Using a completely different business name
Sole traders don't need registration when using their exact personal name (like 'Juanita Brown'). You must register your business name if you add any descriptive words, such as 'Juanita Brown Plumbing'.
Partnerships don't need registration when the business name includes all partners' full names exactly as they appear legally.

Australian Business Number requirement
Before you can register a business name, you need to have an Australian Business Number (ABN) or have an ABN application in progress. The ABN is a unique 11-digit number that identifies your business to the government and community, and according to the Australian Taxation Office, it makes it easier for businesses and all levels of government to interact.
If you don't have an ABN yet, you can apply for one as part of the business name registration process. You can learn more from guides on what an ABN is and how to apply for one.
Choosing and checking a business name
Name selection requires careful verification before you commit to any choice. Check availability and restrictions first to avoid costly registration rejections.
Essential checks before registration:
- Availability: Make sure the name is not already registered
- Restrictions: Check that no prohibited words are included
- Legal compliance: Confirm any industry-specific requirements are met
Name restrictions
Prohibited business names fall into two main categories:
Undesirable names:
- Offensive or inappropriate language
- False government connections (suggests official agency status)
- Misleading royal or charity associations
Restricted names:
- Words requiring special authorisation include terms like 'Bank,' 'University,' and 'Charity.' Additionally, some professional bodies have their own rules; for instance, members of Chartered Accountants Australia and New Zealand cannot include “Chartered” in a registered business name.
- Industry-specific terms needing licenses: 'Architect,' 'Builder,' 'Lawyer'
- Terms that mislead consumers about your business type
And some other laws may impact what you want to call your business. Using industry and professional terms like 'architect' or 'builder' may be restricted to those who are licensed and registered.
You can read more about name availability and restrictions on the Australian Securities and Investment Commission (ASIC) website.
How to find out if a business name is taken
Once you've decided on a few options, it's time to find out if they're available. The Business Registration Service search tool will check the names you've chosen and also check if domain names are available.
ASIC also has a tool that checks the availability of a business name. It checks your proposed name isn't restricted, already registered, undesirable, or contains invalid characters. It's an easy way to save yourself a lot of hassle.
How to find out if a business name is protected
Be aware though, even if the name you've chosen is available to register, you don't have exclusive rights to use it if someone else has already registered it as a trade mark. They're separate processes. So also check your proposed business name with IP Australia for any existing trade marks.
What information you need to register
Having your information ready will make the registration process much smoother. Before you start, make sure you have the following details on hand:
- Your ABN or ABN application reference number
- The business name you want to register
- The registration period you want (one or three years)
- Contact details for the business, including an email and physical address for service of documents
- The business location addresses
