Business name availability is a three-layer check, not one search
ASIC approval, trade mark clearance, and digital availability all need to align. Missing any one of these can create legal or commercial risk. -
The ATO rejects similarity, not just duplication
Even if a name isn’t identical, ASIC can reject it if it’s too similar in sound, structure, or meaning, differentiation must be clear. -
The real risk isn’t rejection, it’s rework after launch
The biggest cost comes from branding, domains, and customer recognition built on a name you can’t legally keep.
Think you’ve found the perfect business name?
Before you get too attached, it’s worth asking one question: is it actually available?
Many business owners spend hours, sometimes days, coming up with a name, only to realise it’s already taken. In some cases, they only find out after launching, when it leads to legal issues, rebranding costs, or trademark conflicts.
In Australia, checking business name availability isn’t just a formality, it’s a critical first step. A name that clashes with an existing business, registered trademark, or even a domain can delay your launch and create unnecessary risk.
This guide shows you exactly how to perform a business name check properly using ASIC, ABN Lookup, and IP Australia so you can register your business confidently and avoid costly mistakes.
Always check trade marks before committing to a name, it’s the most common (and costly) mistake businesses make.
Why is it important to check business name availability in Australia?
You might think that if you don’t see another local business using your name, you’re in the clear. But checking business name availability in Australia goes beyond a quick search, it requires reviewing national registers and existing rights.
The biggest risks include:
- Application rejection by ASIC
If your name is identical or too similar to an existing registered business name, it may not be approved. - Trademark conflicts
If your name overlaps with a registered trade mark, you may face legal action or be forced to rebrand after launch. - Brand confusion
Similar names can confuse customers and dilute your brand, even if the name is technically available. - Poor online visibility
Overlapping names can make it harder for customers to find your business through search or digital channels.
In short, a proper business name check helps you avoid compliance issues, protect your brand, and start your business on the right footing.

How to check business name availability in Australia (Step-by-Step)
Checking business name availability isn’t just one search, it’s a process. Here’s how to do it properly:
Step 1: Start with an online business name checker
The quickest way to begin is by using an online tool like Sleek’s business name checker.
This lets you:
- Instantly check if your name is available
- Test multiple variations quickly
- Get a fast initial indication before moving to official registers
It’s a simple first step to narrow down your options before doing deeper checks.
Step 2: Search the ASIC business names register (official check)
Using ASIC’s business name availability check is your first official check and a critical part of the process.
In Australia, business names are registered nationally through ASIC. This means your name must be available across the entire country, not just in your local area.
What this check does
ASIC’s business name search allows you to:
- Check if a name is already registered
- Identify names that are identical or too similar
- Assess whether your application is likely to be accepted
You don’t need an account to search, simply use the ASIC business names register and enter your proposed name.
Important: Don’t just check exact matches. Look for:
- Similar spellings
- Phonetically similar names
- Names with added words but the same core identity
If a name is identical or too similar, ASIC may reject your application.

Step 3: Use ABN Lookup for additional checks
ABN Lookup is a supporting tool, not a primary one, but it adds an important layer.
It allows you to:
- Identify active businesses operating under similar names
- Cross-check entity names and registration details
- Spot businesses that may not appear obvious in a quick search
However, it’s important to understand its limitation:
ABN Lookup may display historical trading names (pre-2012), which are not actively maintained. So while useful, it should not be relied on as your main availability check.
Step 4: Check IP Australia for trade marks (critical legal step)
This is where many businesses make mistakes.
A name might be available on ASIC but still be legally protected as a trade mark.
Using IP Australia’s trade mark search, you should:
- Search for identical and similar names
- Check relevant classes (based on your industry)
- Review both registered and pending trade marks
Why this matters:
If your name infringes on an existing trade mark, you may be forced to:
- Stop using the name
- Rebrand entirely
- Face legal action
Step 5: Check domain and online availability
Finally, check whether your business name is available as a domain and across key platforms.
This includes:
- Website domains (.com.au, .com)
- Social media handles
- App/store listings (if relevant)
While not a legal requirement, this step is critical for:
- Brand consistency
- Online visibility
- Customer trust
Run multiple name variations early, not just your preferred one, so you don’t have to restart the process if your first choice fails.
What should you do if your business name is taken?
If your preferred name is unavailable, it’s important to approach the next steps strategically. Simply choosing a similar name without proper checks can lead to rejection, compliance issues, or future legal risks.
Follow these steps to move forward correctly:
- Identify the reason for unavailability
Determine whether the name is identical or too similar to an existing ASIC-registered business name, or if it conflicts with a registered trade mark. Each scenario requires a different approach. - Refine the name with meaningful modifiers
Introduce descriptive terms, geographic identifiers, or industry-specific wording to create a name that remains relevant while improving distinctiveness. - Ensure sufficient differentiation
Avoid minor spelling changes or phonetic variations. ASIC assesses similarity beyond exact matches, so the name must be clearly distinguishable. - Reassess trade mark risk before proceeding
If the limitation is due to a trade mark, ensure any revised name does not create infringement risk within the same or related classes of goods or services. - Consider adopting a new name where required
Where conflicts are significant, particularly with trade marks or well-established businesses, selecting a new name is often the most compliant and commercially viable option. - Repeat the full business name check process
Any revised name should be rechecked across ASIC, ABN Lookup, and IP Australia to confirm availability and reduce risk. - Secure related assets promptly
Once a suitable name is identified, secure domain names and digital handles to maintain consistency and prevent third-party conflicts.
Taking a structured approach ensures your final business name is not only available, but also compliant, defensible, and aligned with long-term brand growth.
What to do after you find an available business name
Once you’ve completed your business name availability check and found a name that appears clear, the first step is to secure it properly through the right registration path.
What you do next depends on whether you only need a registered business name, or whether you also need a separate legal entity such as a company.
Step 1: Register your business name with ASIC
In Australia, if you run a business under a name other than your own name, you generally need to register that business name.
- Business names are registered nationally through ASIC, and you can register through ASIC’s online system or the Australian Government’s Business Registration Service.
- To complete the registration, you need an ABN or an ABN application reference number.

Step 2: Decide whether you also need to register a company
Registering a business name does not create a separate legal entity.
- If you want a separate legal structure with limited liability, you may need to register a company.
- The companies register and the business names register are separate, so if your company trades under a name different from its company name, you usually need both.
Step 3: Choose the right structure
- Whether you operate as a sole trader, partnership, or company affects your legal and compliance position.
- A company is a separate legal entity; a business name is not. That distinction matters for liability, ownership, and future growth.
Step 4: Do you need a company constitution?
If you set up a company, you may rely on the replaceable rules under the Corporations Act, use a constitution, or use a combination of both. A constitution is not mandatory in every case, so this should be framed as a structural choice rather than an automatic requirement.
Step 5: Should you register a trade mark?
- Registering a business name does not give you trade mark rights.
- If the name is central to your brand, trade mark protection is a separate step to consider.
Step 6: Keep the registration active
A business name registration must be renewed, usually every 1 or 3 years. That is separate from company annual review obligations, which apply to companies rather than business names.
Business name availability doesn’t equal ownership and it definitely doesn’t equal protection.
Business name vs company name vs trade mark: What’s the difference?
Found a name that looks available? Don’t assume you’re in the clear just yet.
When checking business name availability, it’s important to understand that “available” can mean very different things depending on what you’re checking, business name, company name, or trade mark. Each serves a different purpose, and confusing them is one of the most common mistakes business owners make.
Here’s how they differ:
|
Identifier |
What it means |
What it allows you to do |
Does it give exclusive rights |
|
Business name |
A name registered with ASIC that allows you to trade under it |
Operate your business under a name different from your personal or company name |
No |
|
Company name |
The legal name of a registered company (e.g. Pty Ltd entity) |
Identify your business as a separate legal entity |
No |
|
Trade mark |
Registered intellectual property that protects your brand |
Gives legal rights to use the name in specific classes |
Yes (within scope) |
What it means in practice:
- A business name being available only means you can register and use it under ASIC, it does not stop others from using a similar name.
- A company name being registered only identifies your legal entity, it does not protect your brand commercially.
- A trade mark is what gives you enforceable rights to prevent others from using a similar name in your industry.
A name might be available to register today, but that doesn’t mean it’s safe to use or scalable as a brand. Taking the time to understand these distinctions ensures you choose a name that is not just available but also legally sound and built for long-term growth.

Frequently Asked Questions
Is checking ASIC enough to confirm a business name is available?
No. ASIC only confirms if a name can be registered. You should also check trade marks with IP Australia to ensure the name doesn’t infringe on existing legal rights.
Does registering a business name give me ownership of the name?
No. Registering a business name allows you to trade under it, but it does not give exclusive rights. Trade mark registration is required for legal protection.
How long does a business name registration last in Australia?
Business name registrations can be renewed for 1 year or 3 years, depending on the option you choose at the time of registration.
