How To Check If Your Australian Business Name Is Available

Choosing a business name is exciting - it’s the start of your brand story. But before you print business cards or build a website, it’s crucial to make sure the name is actually available in Australia.

Doing a thorough availability check helps you avoid legal issues, protect your brand, and save money down the track. The good news is, with a clear process (and a few smart checks), you can be confident your business name is free to use - and worth investing in.

In this guide, we’ll walk you through exactly how to check a business name in Australia, the difference between a business name, company name and trade mark, and what to do if your preferred name is already taken. We’ll also cover how to secure your brand properly once you’ve found a winner.

Why Business Name Availability Matters In Australia

A great name is a valuable asset. It’s how customers find you, remember you, and recommend you.

But there are legal reasons to check availability, too. If your name clashes with another business, you could be refused registration, forced to rebrand, or face a complaint for misleading or deceptive conduct under the Australian Consumer Law.

Getting it right at the start means you can promote your business with confidence and avoid expensive rework later.

Step-By-Step: How To Check If Your Business Name Is Available

Here’s a practical checklist you can follow. Each step adds a layer of certainty - aim to tick them all before you commit to signage, domain names or branding.

1) Search the ASIC Business Names Register

Start with the Australian Securities and Investments Commission (ASIC) Business Names Register. This is where all trading names (not company names) are recorded. Search for your exact name and close variations (with and without punctuation, plural/singular, and common misspellings).

ASIC won’t allow you to register a name that is identical or “nearly identical” to an existing registered business name. Think about sound-alike and look-alike risks, too - even if a minor character difference passes the register, it might still confuse customers.

2) Check company names on ASIC

Next, search the ASIC companies register for existing company names. You can’t register a business name that is identical to a registered company name. It’s also risky to choose a name that’s very close to a well-known company, even if technically permitted - reputation and confusion risks can be significant.

3) Search trade marks on IP Australia (ATMOSS)

Trade marks are different from business names. A registered trade mark gives its owner strong rights to exclusively use that brand for specific goods/services across Australia. Search IP Australia’s ATMOSS database for exact matches and similar names. Check both word marks and logos.

If someone has a registered trade mark for a similar name in your industry category, using your proposed name could infringe their rights - even if the ASIC register is clear. If you plan to protect your brand (and we recommend that you do), consider your options to register your trade mark once you’ve chosen a name. Understanding the right trade mark classes is an important part of this assessment.

4) Check domain names

Search availability for .com.au and .au domains, as well as .com (if relevant). Consistency matters: securing a domain that matches your name improves credibility and reduces customer confusion. If your ideal domain is taken, consider whether an alternative (like a different extension) could still work - but be wary of names that could be confused with an existing site.

If you’ll have others using or managing your web address, a simple Domain Name Licence can clarify ownership and usage rights.

5) Search social media handles

Check Instagram, Facebook, LinkedIn, TikTok and YouTube for matching or similar handles. It’s fine if you need to add a short descriptor (like “au” or “hq”), but avoid handles that are easily mistaken for another brand in your space.

6) Do common law and marketplace searches

Run a broad Google search, and look through directories and marketplaces (e.g. Etsy, Amazon, eBay) for similar names in your industry. Even unregistered names can carry “common law” rights if they’ve built a reputation. The aim is to avoid confusion and prevent disputes - especially in the locations or markets you plan to target.

7) Look for restricted or sensitive terms

Some words can be restricted or require consent (e.g. “bank”, “Royal”, or terms implying government affiliation). If your name includes potentially restricted terms, check whether special approvals are needed or consider alternatives.

Business Name Vs Company Name Vs Trade Mark: What’s The Difference?

It’s easy to mix these up - and many founders do. Here’s how they differ (and how they work together):

• Business Name: The trading name you use with customers as a sole trader, partnership or company. Registering a business name with ASIC allows you to trade under that name, but it doesn’t give you ownership of the name in a proprietary sense.
• Company Name: The legal name of your company, which is a separate legal entity. If you trade under the exact company name, you don’t also need a business name. Many businesses find it helpful to understand the differences in detail - see Business Name vs Company Name and Entity Name vs Business Name.
• Trade Mark: A registered right (through IP Australia) that gives you exclusive use of your brand for certain goods/services across Australia. This is what legally protects your brand from copycats and gives you stronger enforcement options.

Think of it like this: a business name is your storefront sign, a company name is the legal name of the entity behind the business, and a trade mark is your enforceable brand protection.

For a strong brand strategy, it’s common to secure all that apply: the business or company name with ASIC, the matching domain, social handles, and a registered trade mark covering how you’ll actually use the name in the market.

What Words Can You Use (And Not Use) In A Business Name?

ASIC can reject names that are identical or nearly identical to existing names, are misleading (for example, implying you’re a government body), or contain restricted terms without consent.

Here are practical tips to stay on the right side of the rules:

• Avoid near-identical variations: Simple punctuation changes, adding “the”, or switching “&” to “and” usually won’t be enough to distinguish your name.
• Watch for sensitivity: Words like “bank”, “trust”, “Royal”, “Commonwealth” and similar terms often require approval or are restricted.
• Be realistic about confusion: Even if you can technically register a similar name, it may still cause problems with customers - and that’s a risk to your brand.

If your preferred name is close to another operator’s, ask yourself whether a customer hearing the name spoken aloud would reasonably assume you’re the same business. If the answer is “maybe”, it’s worth exploring a more distinctive option now rather than rebranding later.

What If Your Preferred Name Is Taken?

Don’t panic - you have options. Start by working through variants that still feel on-brand but reduce confusion risk. You can add a descriptor that’s meaningful (e.g. “Studio”, “Collective”, a location, or your niche), or pivot to a related name that keeps your brand concept intact.

It’s important to understand the legal backdrop here. Two businesses can sometimes use similar names if they’re in completely different industries and there’s no real risk of confusion. But it’s not just a technical rule - reputation and overlap matter. For context on the risks and boundaries, see Can Two Businesses Have The Same Name?

If the exact name is trade marked in your category, consider alternatives. You might negotiate a coexistence letter in rare cases, but usually the safer, faster and cheaper path is choosing a distinctive new name you can truly own.

How To Secure Your Name: Registration And Brand Protection

Once you’ve picked a name that clears your checks, protect it properly. This is where you turn research into real-world rights.

Register the business or company name with ASIC

If you’re a sole trader or partnership, register the business name on the ASIC Business Names Register. If you’re operating through a company, you can choose to trade under the company name or register a separate business name for branding purposes.

If you’d like help with the process, we can handle your Business Name registration, or set up a Company for you and ensure your structure, documents and registrations are all aligned with your goals.

Secure your matching domain(s) and social handles

Register the .com.au and .au versions of your chosen domain, plus any others that make commercial sense. Locking these in early prevents domain squatting and keeps your branding consistent.

If multiple people in your organisation will use or manage the web address, consider a lightweight Domain Name Licence so the business clearly owns the domain and can control how it’s used.

Apply to register your trade mark

This is the step that truly protects your brand at a national level. Filing a trade mark application with IP Australia for your name and/or logo gives you exclusive rights for the goods and services you specify, and a solid basis to stop others using confusingly similar branding.

It’s best to apply for coverage that matches how you’ll actually use the brand. If you’re unsure about scope, filing strategy, or class selection, we can guide you on registering your trade mark and planning the correct classes in Australia.

Keep records of your searches and decisions

Save screenshots and notes of your ASIC, IP and domain searches, plus any professional advice you’ve received. Good records can be helpful later if there’s ever a question about priority or your decision-making process.

Plan for growth (and future names)

If you anticipate new product lines, services or sub-brands, consider whether your chosen name or trade mark strategy can stretch with you. Some owners register a core brand as a trade mark first, then add trade marks for key sub-brands as they expand.

Practical Naming Tips That Save Headaches Later

Beyond the formal checks, a few practical habits make a big difference:

• Choose distinctive over descriptive: Unique names are easier to protect. Highly descriptive names can be hard to trade mark.
• Prioritise clarity: If your name is often misheard or misspelled, customers will struggle to find you online.
• Think long term: Will this name still fit if you expand into new locations or products?
• Align your structure and brand plan: If you’re bringing in co-founders or investors, you may prefer a company from day one. That decision ties into naming, domain management and brand ownership, so consider the full picture before you register.

If you’re weighing up the pros and cons of trading under a business name versus the company’s legal name, it can help to revisit the differences between a Business Name vs Company Name and how your entity name relates to your trading name.

Key Takeaways

• Check availability in layers: ASIC business names, ASIC company names, trade marks (ATMOSS), domains, social handles and general online searches.
• Business names, company names and trade marks each serve a different purpose - for strong protection, consider all three where they apply.
• Avoid names that are identical or nearly identical, or that could mislead the public or require approvals for restricted terms.
• If your preferred name is taken (or too close), consider distinctive alternatives rather than risking confusion and future disputes.
• Once you find a clear name, secure it: register with ASIC, lock in domains and handles, and apply to register your trade mark with the right classes.
• Document your checks and decisions, and align your naming plan with your structure and long-term strategy.
