Is My Business Name Taken? How to Check in 5 Minutes

You just landed on the perfect business name. It sounds right, it feels memorable, and you can already picture the logo. Then the dread kicks in: is my business name taken?

This is the exact moment where most founders either waste an entire afternoon clicking through a dozen different websites, or worse, skip the research entirely and find out months later that someone else already owns the domain, the trademark, or the Instagram handle.

Neither outcome is great. The good news is that a thorough name availability check doesn't have to take hours. If you know where to look and what to check, you can cover all your bases in about five minutes.

Here's the thing most people miss: checking if a business name is "taken" isn't just about the domain. A name can be available as a .com but already trademarked in your industry. Or the domain might be free, but every social media handle is locked up by someone else. You need to check multiple layers to actually know if a name is safe to use.

Let's walk through the complete process.

The 5-Layer Name Availability Check

Think of name availability as five separate questions, not one. A name is only truly "available" if you can claim it across all five layers. Let's use a running example: say you're launching a productivity tool and you want to call it CoolStartup.

Layer 1 — Domain Availability

Start with the domain. This is the fastest check, and it's often the dealbreaker. If coolstartup.com is already registered, you need to know that upfront before you fall in love with the name.

Why .com first? Because it's still the default. When someone hears your business name, they'll type yourname.com into their browser. Not .io, not .co — .com. Studies consistently show that consumers trust .com domains more than alternatives, and they're easier to communicate verbally. "Visit coolstartup dot com" is simple. "Visit coolstartup dot i-o" leads to confusion.

That said, .com isn't the only option. If coolstartup.com is taken but coolstartup.io or coolstartup.co is available, that might work depending on your audience. Tech-savvy users are comfortable with alternative TLDs. A local bakery's customers might not be.

Beyond the primary domain, check a handful of common extensions: .com, .net, .org, .io, .co, .ai. If your name is available across multiple TLDs, that's a strong signal. If it's taken across all of them, the name is probably crowded.

Layer 2 — Trademark Search

This is the layer most people skip. And it's the one that can cost you the most money down the road.

A domain being available does not mean the name is legally clear. Someone could own a registered trademark on "CoolStartup" for software products, even if they don't own coolstartup.com. If you launch under that name, you could receive a cease-and-desist letter, lose your domain through a UDRP dispute, or face a trademark infringement lawsuit.

The primary database for U.S. trademarks is USPTO TESS (Trademark Electronic Search System). Search for your exact name and close variations. Pay attention to the Nice Classification — trademarks are registered by product/service category, called "classes." There are 45 classes total. A trademark for "CoolStartup" in Class 25 (clothing) doesn't block you from using it in Class 42 (software). But a trademark in your same class is a serious problem.

When searching TESS, don't just search the exact name. Search for phonetic equivalents and partial matches too. "Kool Startup" or "Cool Start Up" could still create a conflict if they're in the same industry.

For a deeper walkthrough, read our guide on how to check if a name is trademarked. Or save time and use our trademark search tool, which scans the USPTO database and flags conflicts in your specific class.

Layer 3 — Social Media Handles

Even if the domain and trademark are clear, you still need social media. And handle availability is surprisingly competitive. Short, clean handles like @coolstartup get snatched up fast — sometimes by active businesses, sometimes by squatters, sometimes by someone who created an account in 2012 and never posted.

Check the platforms that matter for your business:

• Twitter/X — essential for B2B, tech, and media companies
• Instagram — critical for consumer brands, e-commerce, food, and lifestyle
• TikTok — increasingly important for any brand targeting audiences under 40
• LinkedIn — important for B2B services and professional brands

Ideally, you want the same handle across all platforms. Consistent handles make your brand easier to find and look more professional. If @coolstartup is available on Twitter but taken on Instagram, you'll be stuck with @coolstartup_hq or @getcoolstartup on one platform, which creates a fragmented brand experience.

You can check each platform manually, or use our social handle checker to scan all major platforms at once.

Layer 4 — State Business Registration

If you're forming an LLC or corporation in the United States, your business name needs to be unique within your state of registration. Two LLCs in Delaware can't have the same name. This is a legal requirement, not just a branding preference.

Each state maintains a business entity database through its Secretary of State website. The search process varies by state, but it's generally straightforward: go to the website, find the business name search tool, and type in your name.

A few things to keep in mind:

• Exact matches and "deceptively similar" names are both blocked. "CoolStartup LLC" and "Cool Startup LLC" would likely conflict.
• This only applies within the state you're registering in. A company called CoolStartup in California doesn't block you from registering CoolStartup in Texas (though the trademark issues discussed in Layer 2 still apply).
• Name reservations expire. Some states let you reserve a name for 60-120 days before filing your formation documents. If you find your name is available, consider reserving it while you finalize everything else.

For the most common states (Delaware, Wyoming, California, Texas, Florida, New York), the Secretary of State websites are free to search. Just Google "[your state] Secretary of State business name search" and you'll find it.

Layer 5 — Google It

This sounds obvious, but it's the layer that catches what the other four miss. Google your business name — in quotes — and see what comes up.

You're looking for three things:

1. Active businesses using the same name. Even if they don't have a trademark, an established business with the same name creates market confusion. If "CoolStartup" returns a funded SaaS company on page one of Google, you're going to have a brand recognition problem.
2. Strong SEO competitors. If someone else ranks for your exact business name, you'll struggle to rank for your own brand name. That's a real problem. People who search for you by name will find someone else instead.
3. Negative associations. Make sure the name doesn't share space with anything embarrassing, controversial, or inappropriate. Check the first three pages of results, not just the first.

Also try Google Image Search and Google News. Sometimes a name is clean in regular search results but tied to news stories or visual brands that could create confusion.

This step takes two minutes and can save you months of headaches.

What to Do If Your Name Is Taken

So you ran through all five layers and discovered a conflict. The .com is registered. Or there's a trademark in your class. Or every social handle is taken. Don't panic — you have options.

Try Variations With a Prefix or Suffix

If coolstartup.com is taken, check variations like:

• getcoolstartup.com — the "get" prefix is popular and sounds action-oriented
• usecoolstartup.com — works well for SaaS and tools
• coolstartuphq.com — "HQ" signals a company homepage
• tryCoolstartup.com — great for products with free trials
• coolstartupapp.com — if you're building a mobile app

The downside: your brand name and your domain won't match exactly. That creates friction. But plenty of successful companies have made this work — Stripe's original domain was stripe.cc before they acquired stripe.com.

Consider Alternative TLDs

If coolstartup.com is taken but coolstartup.io is available, that might be good enough — especially if you're in tech. Here's a quick breakdown of alternative TLDs and when they work:

• .io — popular with developer tools and tech startups. Well-recognized in the industry.
• .co — a general-purpose alternative. Used by companies like Twitter (t.co) and Google (g.co).
• .ai — perfect if you're building anything in the AI/ML space. Increasingly mainstream.
• .app — Google-owned TLD, good for mobile apps. Requires HTTPS by default.
• .dev — another Google-owned TLD, aimed at developers and dev tools.

The rule of thumb: alternative TLDs work better for tech and B2B companies than for consumer brands. If your target customer is a developer, .io is fine. If your target customer is your neighbor, stick with .com.

Use our bulk domain checker to test your name across dozens of TLDs at once.

Buy the Domain on the Aftermarket

Sometimes the .com is registered but not actually being used. The owner might be willing to sell. Domain aftermarket platforms like Afternic, Sedo, and Dan.com list domains for sale, and many "parked" domains (those showing ads or a blank page) have a price tag if you know where to look.

Prices vary wildly. A short, generic .com might cost $5,000 to $50,000+. A longer, less common name might be available for $500 to $2,000. Some owners are open to negotiation; others have firm prices.

Our aftermarket lookup tool checks whether a taken domain is listed for sale and shows you the asking price across multiple marketplaces. It can save you hours of hunting across different platforms.

Pivot to a New Name

Sometimes the best move is to let go. If your name has conflicts across multiple layers — the .com is taken, there's a trademark in your class, and someone else is ranking for the name — fighting for it isn't worth the effort or legal risk.

Starting fresh isn't a failure. Some of the biggest companies in the world pivoted on their names: Google was originally "BackRub." Nike was "Blue Ribbon Sports." The name you end up with might be better than the one you started with.

If you need inspiration, our guide to naming a startup covers proven naming strategies, and the Name Studio can generate hundreds of available options based on keywords you provide.

The All-in-One Shortcut

Running through five separate checks is thorough, but it's also tedious if you're evaluating multiple name candidates. That's exactly why we built the Validation Suite on MatchMyDomain.

Instead of checking each layer individually, the Validation Suite runs all of them at once. Enter a business name and get a single report that covers:

• Domain availability across all major TLDs
• Trademark conflicts in the USPTO database
• Social media handle availability across major platforms
• Aftermarket pricing if the domain is already registered
• A confidence score telling you how "safe" the name is to use

It's the fastest way to go from "I have a name idea" to "I know this name is clear" without opening ten browser tabs.

Frequently Asked Questions

Can two businesses have the same name?

Yes, in some cases. U.S. trademarks are registered by class (product/service category), so two businesses can share a name if they operate in different industries. A clothing brand called "Atlas" and a software company called "Atlas" can coexist legally. However, state business registrations require unique names within the same state, and sharing a name always creates brand confusion — even if it's technically legal. The safer move is always to find a unique name.

Is checking the domain enough to know if a name is available?

No. A domain being available only means nobody has registered that specific web address. It says nothing about trademarks, state business registrations, or existing companies using the name offline. We've seen cases where a .com is wide open, but the name is trademarked in the exact same product class. Always check all five layers before committing.

How much does it cost to buy a taken domain?

It depends entirely on the domain. Short, generic .com domains (like "cloud.com" or "startup.com") can sell for six or seven figures. But most business-name domains trade in the $500 to $5,000 range. Some owners list a "buy now" price; others require negotiation. Use our aftermarket tool to check if a taken domain is listed for sale and at what price.

What if the social handles are taken but the domain and trademark are clear?

This is common and usually workable. Try handle variations like @getcoolstartup or @coolstartuphq. On some platforms, you can also reach out to the current handle owner — if the account is inactive, platforms like Twitter/X sometimes release handles through their username squatting policy. The most important thing is consistency: pick one variation and use it across every platform where your exact name isn't available.

Start Checking Right Now

The longer you wait, the more likely someone else registers the domain, files the trademark, or grabs the social handles. Name availability changes daily. If you have a name in mind, check it today — not next week.

Start with a free domain check, then work through the other layers. Or skip straight to the Validation Suite and check everything at once. Either way, five minutes of research now can save you months of rebranding later.
