How to Check if a Business Name is Taken

A business name can be "taken" in up to four completely separate ways: the .com can be owned by someone else, a trademark can be registered in your category, a state or county registration can conflict, and your social handles can be squatted. Each check is different, and passing one does not mean you pass the others. This guide walks through all four in the order that catches problems fastest.

Why a business name can be taken in four separate ways

A common mistake is treating "is this name taken?" as a single question with one answer. In practice there are four independent layers.

The .com domain is a registration at a domain registrar. Anyone can register a .com for any name, even if they have no trademark or business intent, and squatting is widespread. Owning the .com gives you a web presence but no exclusive commercial right to use the name.

A trademark is a federally registered right (USPTO in the US) to use a name in commerce in a specific category. A live trademark in your category blocks you from using that name even if the .com is free.

State business registration is a county or state-level record that a business is operating under a given name. It is not a trademark and does not give national protection, but a conflicting DBA registration in your state can block the entity filing.

Social handles are not legal rights, but a squatted Instagram or Pinterest handle on your exact brand name is a practical problem that fragments your brand identity across platforms.

The order below prioritizes speed: domain first because it is free and instant, trademark second because it is the most legally significant, state third, handles last.

Step 1: Check .com domain availability against the live registry

The fastest first check is the .com domain, because roughly 92.6 percent of brandable .coms are already taken (from our own dataset of real name ideas checked against the live registry). A taken .com is a strong signal that someone is already using the name commercially.

Do not rely on a registrar autocomplete, which can lag by hours. Use a real-time RDAP lookup: lookup.icann.org, the brand name checker at domaingenius.ai/tools/brand-name-checker, or the DomainGenius generator which verifies every suggestion against the live registry as it generates.

If the .com is taken: check who owns it at lookup.icann.org (enter the domain, click WHOIS). A parked-and-for-sale domain means you can buy it at a premium or adjust the name. An active business site means the name is very likely in active commercial use and you should assume someone else is using it.

Step 2: Run a free USPTO trademark search

A trademark search is the most legally significant check and the one most founders skip. A registered trademark in your category gives the owner the right to demand you stop using the name, even if you registered the .com first.

The free search tool is USPTO TESS at tmsearch.uspto.gov. Search your exact name and close variations (misspellings, plurals) filtered to "live" status and International Classes matching your business. A clean TESS result is not a legal opinion, but it rules out obvious conflicts at zero cost.

Class examples: Class 42 (software services) and Class 9 (software products) for a software tool; Class 25 for clothing; Class 41 for educational or media brands. A trademark in Class 25 would not block a software product in Class 42 from using the same name.

If you find a conflict: pick a different name. If the search is clean: proceed with reasonable confidence, and registering your own trademark becomes worthwhile once the business has revenue to protect.

Step 3: Check state and county business name registrations

If you plan to operate as a sole proprietorship, LLC, or corporation, most US states require a business name that does not conflict with an existing registration in the same state. The state-level conflict does not carry federal trademark weight, but it can block the entity filing.

Most state Secretary of State websites have a free business name search. Search "your state Secretary of State business search" to find the right tool. Look for active registrations matching your exact name or close variants in the same business category.

Note: a clear state search does not override a federal trademark. Federal trademark law supersedes state registration in cases of conflict.

Step 4: Check social handles and the Google landscape

Social handles are not legal rights, but a squatted handle with your brand name is a practical branding problem. Your audience searches for you on Instagram, Pinterest, and TikTok by the same name they know from your .com. A fragmented handle forces underscores, numbers, or "the-" prefixes, all of which erode brand trust.

Check Instagram (search the exact handle), Pinterest, TikTok, and YouTube if relevant. A dormant handle (last post more than two years ago, no profile picture) can often be reclaimed via the platform trademark or impersonation claim process after you own the name legally.

Google the exact name in quotes. If the first page is dominated by an established business in your category, you have a brand-search collision problem that no trademark filing fixes: you will lose branded search traffic to them indefinitely.

The four-check sequence: a printable checklist

Run all four checks on every finalist name before you commit:

1. .com availability via real-time RDAP lookup (free, 30 seconds). Use lookup.icann.org or domaingenius.ai/tools/brand-name-checker.

2. USPTO TESS trademark search in your class (free, 5 minutes). Go to tmsearch.uspto.gov, search the exact name, filter to Live status.

3. State Secretary of State business name search (free, 2 minutes). Search your state name plus "Secretary of State business search".

4. Social handles and Google (free, 3 minutes). Check Instagram, Pinterest, TikTok, and Google the name in quotes.

A name that clears all four is a name you can build on. A name that clears three is almost always a risk you will pay to fix later. The total time for all four checks on a finalist is under 15 minutes.

Frequently asked questions

Does owning the .com mean I own the business name?

No. A domain registration gives you a web address, not an exclusive commercial right to the name. A trademark in your category is the legal instrument that protects the name across the market. Owning the .com is essential for your brand, but it does not block a trademark holder from demanding you stop using the name commercially.

Can I use a business name if the .com is taken?

Using the name commercially is a legal question, not a domain question. If no one holds a trademark in your category and there is no obvious commercial conflict, you can operate under the name. But without the matching .com you will lose direct-type traffic to whoever owns it forever. The practical advice is to adjust the name until you find one where the .com is also free.

How do I search the USPTO trademark database for free?

Go to tmsearch.uspto.gov and use the free TESS search. Select "Basic Word Mark Search." Search your exact name, filter to "Live" status, and look for registrations in International Classes matching your product category. A clean result is not a legal clearance opinion, but it rules out the most obvious conflicts at zero cost.

What is the difference between a trademark and a business registration?

A trademark is a federally registered exclusive right to use a name in commerce in a specific product or service category. A business registration (DBA, LLC, corporation) is a state or county administrative record that a business is operating under a name. Business registration does not give trademark rights and does not protect the name nationally. Federal trademark supersedes state business registration in cases of conflict.

What if someone is using my name without a trademark?

Common law trademark rights can exist without a federal registration if a business has been using a name in commerce. If an established company is actively using your target name in your market, they may have common law rights even with no USPTO filing. The Google collision check surfaces this risk. When in doubt, consult a trademark attorney before committing to the name.

How do I check business name availability by state?

Each US state has a Secretary of State website with a free business entity search. Search your state name plus "Secretary of State business search" to find the right tool. Search the exact name and close variants with an "active" status filter. Most searches are instant and free. Note that a clear state result does not override a federal trademark conflict.

Do all four checks cost money?

No. All four checks in this guide are free: the .com RDAP lookup (lookup.icann.org or domaingenius.ai), the USPTO TESS trademark search, the state Secretary of State search, and the social handle and Google checks. Paid tools and attorney opinions exist but are not required for the initial clearance pass. Professional fees become worthwhile if you need a formal trademark clearance opinion or want to file your own registration.
