How to Check If a Business Name Is Available: The 5-Step Checklist

To check if a business name is available, run five checks before you commit: search the trademark register (USPTO in the US, INPI in Brazil), check domain availability, check the exact social handles, search your state or local business registry, and run a plain Google and app-store search. A name is only truly available when it clears all five at once — an open domain with a registered trademark on it is not available, and a free handle with a live competitor under the same name is not available either. This article walks you through each check, in order, so you can clear a name in about twenty minutes instead of discovering the conflict after you have printed the packaging.

This is the verification step, not the creativity step. If you are still generating and shortlisting names, start with how to choose a brand name — that guide covers what makes a name memorable and how to build a shortlist. Come back here the moment you have two or three finalists you actually like. The goal now is simple and unglamorous: prove that the name you love is legally and practically yours to use before you spend a cent building on it.

Why a Single Check Is Not Enough

The most common naming mistake is treating one clear signal as a green light. Founders check the .com, see it is available, buy it, and start building — only to get a cease-and-desist months later from a company that quietly held the trademark all along. Each of the five checks below protects against a different failure, and they do not substitute for one another. The domain protects your web address. The trademark protects your legal right to the name in your category. The handles protect your social presence. The business registry protects against a duplicate legal entity. The Google and app-store search catches the active businesses that never formally registered anything but would still confuse your customers.

Think of it as a checklist where every box has to be ticked, not a scoreboard where four out of five is a pass. The one you skip is usually the one that comes back to bite you.

The 5-Step Availability Checklist

Here is the whole process on one screen — the check, where to run it, and the rough cost. Work down the list in order, because the trademark check is the one most likely to kill a name, and it is cheaper to kill it early than after you have fallen in love with the logo.

Step 1 — Search the Trademark Register

This is the check that carries real legal weight, so do it first. A registered trademark gives its owner the right to stop others from using a confusingly similar name in the same category — which means this is the check most likely to force a rebrand if you ignore it. In the United States, use the trademark search on the USPTO website (uspto.gov). In Brazil, search the marcas database at INPI (inpi.gov.br). Look for identical names and for names that sound or look confusingly similar in your business class, not just exact matches. "Zappos" and "Zapos" selling the same thing would collide; the register cares about likelihood of confusion, not spelling.

A clear search is encouraging but not a guarantee — trademark clearance has genuine nuance, and for a name you plan to build a company on, a trademark attorney or industrial-property agent running a full clearance is money well spent. Treat your own search as the fast filter that eliminates the obvious conflicts before you pay anyone.

Step 2 — Check the Domain

Once the name survives the trademark check, see whether you can actually own the web address. Check availability through a registrar — registro.br for Brazilian .br and .com.br domains, or any ICANN-accredited registrar for .com and the rest. A free exact-match .com is ideal, but do not abandon a great, trademark-clear name just because the .com is taken. A strong .co, a country domain like .com.br, or a brandable variant is a perfectly good launch position, and .com scarcity is the norm now, not the exception. What you should avoid is a name whose only available domain forces awkward hyphens or misspellings that customers will never type correctly.

Step 3 — Check the Social Handles

Check the exact handle on the platforms you will actually use — there is no prize for reserving a name on a network you will never post to. Look for the clean @yourname on Instagram, TikTok, X, YouTube, and LinkedIn as relevant. As with domains, a taken handle is not automatically a dealbreaker; a consistent variant like @yournameHQ or @getyourname across every platform is far better than the perfect handle on one network and chaos everywhere else. Consistency across handles is what makes you findable and what protects your recognition, which is the whole point of a name in the first place.

Step 4 — Search the Business Registry

A trademark protects a brand name; a business registry protects a legal entity name, and they are not the same thing. In the United States, search your Secretary of State business-entity database for an existing company registered under the name — this is usually done at the state level. In Brazil, check the Junta Comercial of your state, where the nome empresarial (the company's legal name) is protected within that state's borders. Because Brazilian company-name protection is state-scoped while trademark protection is national, clearing your Junta Comercial does not clear you nationally — that is exactly why the INPI trademark check in Step 1 exists. Run both.

Step 5 — Run a Google and App-Store Search

The final check catches everything the official registers miss: the active local business, the popular app, the well-known creator using the name informally without ever filing a trademark or registering a company. Search the exact name on Google, then on the App Store and Google Play. You are looking for anyone with real presence and audience overlap — a business your customers could plausibly confuse with yours. A common word used by a hardware shop three states away is usually fine; a growing app in your exact category is a warning sign, even if the register is technically clear. Reputation collisions confuse customers just as much as legal ones.

What "Available" Actually Means

A name is available when it passes all five checks together — not when it wins four of them. The pattern that trips people up is the partial pass: the domain is open but the trademark is taken, or the handles are clean but a competing app already owns the space in customers' minds. Availability is an AND, not an OR. If you have one hard conflict in the category that matters most (usually the trademark), it is almost always faster and cheaper to pick a different name now than to fight for one that was never fully yours.

“The cheapest rebrand is the one you avoid by spending twenty minutes on availability checks before you commit.”

After the Name Clears: Lock It In

The moment a name passes all five checks, move fast to claim what you can, because "available today" is not "available next week." Register the domain, reserve every social handle in one sitting, and put the trademark filing on your near-term list — you do not always have to file the day you launch, but you do want to file before the name has enough traction to attract a copycat. Then the real work begins: turning a cleared name into a brand people recognize.

A name on its own is just a word. What makes it a brand is the system around it — the positioning, the voice, the color palette, the logo, and the guidelines that keep it all consistent. That is exactly what a brand kit assembles into one coherent package; if the term is new to you, what is a brand kit breaks down every component and why they need to come from the same brief. A verified name plus a coherent brand kit is the difference between a business that looks improvised and one that looks like it meant to exist.

Clear the name, then claim it in one sitting: register the domain, reserve every handle, and put the trademark filing on your calendar. "Available today" expires fast — a name is only yours once you have secured it across all five surfaces you just checked.

The Bottom Line

Checking a business name is not glamorous work, but it is the twenty minutes that separates a smooth launch from an expensive rebrand. Run all five checks — trademark, domain, handles, business registry, and a plain Google and app-store search — and treat the name as available only when every box is ticked. The founders who skip this step rarely save time; they just move the cost downstream, where it arrives with interest. Clear the name properly once, then spend your energy on the thing that actually builds recognition: a coherent brand that shows up the same everywhere the name does.
