Business Naming
How to check if a business name is taken
Four checks, one flow: the USPTO trademark register, your state business registry, the domain, and the social handles. Run them in the right order and you will know whether a name is genuinely yours to take — before you spend a cent on it.
To check if a business name is taken, run four checks: search the USPTO trademark register for similar marks in your industry, your Secretary of State’s registry for existing entities, a live domain lookup for a usable .com, and the social handles you will use. A name must clear all four before you commit to it.
Most people check one thing — usually the domain — and assume the name is free. It is the most common naming mistake we see, and the most expensive: a domain can be wide open while the name itself is a registered trademark in your industry, which is the one barrier you cannot simply work around.
This is the whole availability check in one place, in the order that saves you the most wasted effort: legal first, technical second. Clear these four and you can register or trademark with confidence.
The flow
Four checks, in the right order
Run the availability checks legal-first: the federal trademark register, then your state entity registry, then the domain, then social handles. The legal checks are the ones that can kill a name outright, so clear them before you invest time chasing a domain for a name you may not be allowed to use.
- 1
Search the federal trademark register
Start at the USPTO trademark search for identical and confusingly similar marks in your goods/services class. A federally registered mark in your field is the hardest barrier to clear — check it first so you do not waste time on a name you can never own.
- 2
Check your state business registry
Search your Secretary of State’s business database for an existing entity using the name. Most states will not let you register an LLC or corporation with a name already taken in that state, so this decides whether you can even form the entity.
- 3
Look up the domain
Check whether a usable web address is available live — ideally the exact-match .com. Do not rely on a generator’s “available” badge; look it up yourself, because a taken or parked domain quietly shapes which name you can realistically use.
- 4
Check the social handles
Confirm the handles are free on the platforms you will actually use. You rarely need every network, but consistent handles on your core two or three make the brand findable and trustworthy.
At a glance
Where to check each thing
| Check | Where | What it tells you | Why it matters |
|---|---|---|---|
| Federal trademark | USPTO trademark search | Whether a similar name is legally protected in your industry | A registered mark can block your name nationwide |
| State entity name | Your Secretary of State registry | Whether the name is already used by an entity in your state | Decides if you can form the LLC / corporation |
| Domain | A live domain registrar / WHOIS lookup | Whether a usable web address (ideally the .com) is free | A missing .com quietly reshapes the shortlist |
| Social handles | The platforms you will actually use | Whether consistent handles are available | Consistency makes the brand findable and credible |

When a name is clear — and when to walk away
One red flag is enough to keep a backup name ready. A trademark conflict in your industry is close to fatal; a missing domain is a nudge to reconsider rather than a hard stop.
Don’t be fooled
Four things a quick check misses
“Available” is more nuanced than it looks
The databases make availability look binary — the name is there or it isn’t. In practice, the most costly mistakes hide in the gaps: a name that has no exact match but plenty of confusingly similar ones, or a business with real common-law rights that never appears on any register.
Reading the result well matters as much as running the check. Treat a clean exact-match search as a green light to look harder, not as final clearance — especially for a name you intend to build a brand around.
When the stakes are high, a professional clearance search or a trademark attorney is worth it. The filing process itself is covered in how to trademark a business name.
The traps
“No exact match” is not “clear”: The trademark test is confusion, not identity. A name merely similar to a registered mark in a related class can still be refused or challenged. Search for variants, not just your exact string.
Common-law rights are invisible on the register: A business that never registered a trademark can still hold rights from using the name in commerce. A plain web and directory search catches users the official databases miss.
State-clear is not nationwide-clear: Passing your Secretary of State’s check only means the name is free to register as an entity in that state. It says nothing about trademark rights that reach across state lines.
A free handle today can vanish tomorrow: Handles are not reserved by checking them. If the name clears everything else, secure the domain and core handles quickly rather than assuming they will wait.
