How to Check if a Business Name Is Taken (Domain, Trademark, Social)
A business name is "available" only if it clears four separate checks: trademark, domain, business registry, and social handles. Most people check the domain first because it's the easiest, but that's the wrong order. A name with an open domain and a conflicting trademark is not available, and finding that out after you've bought the domain and printed cards is an expensive lesson.
Here's the sequence that saves you from that, starting with the check that can veto everything else.
1. Trademark search first (this can veto everything)
A registered trademark can stop you from using a name even if the domain is free and no one else has the social handle. So check this before you spend a dollar.
For the United States, search the USPTO's trademark database (the system formerly known as TESS, now searchable through the USPTO's trademark search tool at uspto.gov). Look for your exact name and close variants in your industry class. Trademarks are class-specific, so "Apple" in fruit and "Apple" in computers can coexist, but a match in your own category is a real problem.
Outside the US, search the equivalent office: the EUIPO for the European Union, the UK IPO for Britain, WIPO's Global Brand Database for an international sweep. A plain Google and AI search for the name plus "trademark" catches the obvious conflicts these databases sometimes bury.
This is a screening step, not legal advice. If the name is important and looks close to an existing mark, a trademark attorney's opinion is cheap relative to a rebrand.
2. Domain availability
Now check the domain. You want the .com if you can get it, because it's still what people type and assume. Search a registrar directly rather than trusting a "domain finder" that may upsell you.
A few realities of domain checking:
- If the
.comis taken but parked with no real site, it may be for sale. Prices range from reasonable to absurd; decide what the exact match is worth before you inquire. - A
.co,.io, or.appis a fine alternative for many businesses, but know that some customers will still type the.comand land on whoever owns it. - Avoid working around a taken
.comwith hyphens or creative spelling.get-yourname.comandyournameapp.comcost you traffic and credibility.

3. State and national business registries
If you're forming an actual legal entity, the name has to be available in your jurisdiction's business registry, and this is separate from trademark. In the US, that's your Secretary of State's business entity search, done state by state. Two businesses can't register the same or a confusingly similar name in the same state.
Search your home state first, then any state you plan to operate in. Outside the US, this is your national companies register (Companies House in the UK, for example). A name can be trademark-clear and domain-available but already registered as an LLC in your state, which blocks you from forming under it.
4. Social media handles
Last, check the handles. You want the same name (or a consistent variant) across the platforms you'll actually use. Check each platform directly rather than relying on a bulk "username checker," which is often out of date.
Handles are the most forgiving check. A taken handle is annoying but rarely fatal; you can add a prefix or suffix (@getyourname, @yourname_hq) and move on. Don't let a taken Instagram handle kill a name that's clear on trademark, domain, and registry. The priority runs in the opposite direction.
The check order, summarized
| Order | Check | Where | If it's taken | | --- | --- | --- | --- | | 1 | Trademark | USPTO / EUIPO / WIPO | Stop. Pick another name. | | 2 | Domain | A registrar directly | Consider alternatives or a different TLD | | 3 | Business registry | Secretary of State / national register | Must resolve before forming the entity | | 4 | Social handles | Each platform directly | Add a prefix; rarely a dealbreaker |
Run them in this order and you fail fast on the checks that matter most, before you've invested in the ones that don't.
When the name is taken: generate alternatives
If a name fails one of the early checks, don't force it. The fastest way to find a clear name is to generate a batch of options and run the good ones through the same four checks. Our business name generator produces alternatives from your keywords, which gives you a list to screen instead of staring at a blank page. For the strategy behind picking names that are both brandable and searchable, see business name generator strategies for SEO.
Generate a dozen candidates, kill the ones with obvious trademark or domain conflicts in thirty seconds each, and you'll usually have two or three survivors worth taking seriously.
A quick note on AI and Google search
One check people skip: search the name plainly, in both Google and an AI assistant like ChatGPT. Databases are authoritative for trademarks and registries, but they miss the business that's operating under a name without having registered anything formal, the local shop, the popular indie product, the well-known creator. A plain search surfaces those in seconds. If the first page of results is already full of another company using your exact name, that name is effectively taken for practical purposes even when every formal database comes back clean, because you'll spend years fighting for the search results.
This matters most for the discoverability side of the decision. A name that's legally available but shares the search results with an established brand means customers googling you will find them instead. Weigh that against how attached you are to the name. Sometimes a slightly less perfect name that owns its search results is the better business choice.
Frequently Asked Questions
What's the first thing to check for a business name?
Trademark, not the domain. A registered trademark in your industry can stop you from using a name even if the domain and social handles are free, so screening the USPTO (or your country's equivalent) first prevents you from investing in a name you can't legally use.
Is a business name available if the domain is free?
Not necessarily. An open domain says nothing about trademarks or business registries. A name can have a free .com and still be a registered trademark in your category or an existing LLC in your state, either of which blocks you. Check all four: trademark, domain, registry, and handles.
How do I check if a name is trademarked?
Search your national trademark office's database: the USPTO trademark search tool in the US, the EUIPO in Europe, or WIPO's Global Brand Database internationally. Look for your exact name and close variants within your industry class, since trademarks are class-specific. For anything high-stakes, confirm with a trademark attorney.
Do I need the .com domain?
It helps, because people still default to typing .com, but it's not mandatory. A .co, .io, or .app works for many businesses. Avoid hyphens or altered spellings to dodge a taken .com, since those cost you traffic and look less credible than a clean alternative TLD.
What if the business name I want is taken?
Generate alternatives and screen them fast. Produce a batch of candidates from your keywords, then run each promising one through the trademark, domain, registry, and handle checks. It's quicker to filter a list of options than to fixate on a single taken name.
