Naming advice is mostly written backward: brainstorming first, legality later. Founders who work that way fall in love with names they cannot keep, and the expensive version of that mistake (a federal trademark letter two years into building a brand) is entirely preventable with an afternoon of checks. Here is the sequence that puts the clearance before the commitment, and the map of which registration actually protects what.
The Four Clearance Systems
1. The state entity record. The gate for formation: your name must be distinguishable from every entity registered in your state, with an LLC designator and without restricted words. "Distinguishable" is strict: punctuation, spacing, and designator swaps do not differentiate, so "Summit Consulting, LLC" fails against "Summit Consulting Inc." Run it through the availability check before anything else, because a blocked name here ends the conversation.
2. The federal trademark register. The check that outranks the state's: USPTO registration gives its holder nationwide rights in their class of goods or services, and state approval of your entity name is no defense. Search the USPTO database for your name and close variants in your industry; a conflict here means choosing between a different name now or a possible forced rebrand later. The full picture, including when to file your own, is in the trademark guide.
3. The common-law landscape. Trademark rights in the US begin with use, not registration: an unregistered business using the name in a territory has rights there. A plain web and social search for the name plus your industry surfaces these users; a competitor in your space with your name is a real conflict whether or not they ever filed anything.
4. Domains and handles. No legal force, full practical force: check the .com and the social handles in the same pass, because discovering they belong to someone hostile after formation is a bad week. Same-day domain squatting on names you searched publicly is rare but real; when you decide, register the domain the same day.
What Each Registration Actually Protects
| Registration | What it protects | What it does not |
|---|---|---|
| Entity formation | The exact name on your state's entity record | Other states; anyone's trademark rights |
| DBA registration | The right to operate under the alias in that jurisdiction | No exclusivity in most states; no liability shield |
| Federal trademark | Nationwide brand rights in your class of goods/services | Unrelated industries; purely descriptive names |
| Domain | The address itself | Nothing about the name legally |
The layering explains the standard strategy: form the entity (in-state claim), register the trademark once the brand is real (national claim), and hold DBAs for additional brand names under one entity (see LLC vs DBA). Each layer costs more than the last and protects proportionally more.

If you would rather not do this yourself, we prepare the articles, check name availability with the state, and file it for you. Or keep reading and file it on your own. This guide covers everything you need either way.
Naming Strategy That Survives the Checks
Three practical rules raise the odds that a name you love clears the gauntlet. Distinctive beats descriptive twice over: invented and arbitrary names ("Sunfjord," "Copperline") clear crowded records more easily and receive far stronger trademark protection than descriptive ones ("Best Plumbing Services"), which trademark law treats as barely protectable. Generate in batches of ten: check availability across all four systems before ranking favorites, because attachment forms fast and clearance rates run low in crowded industries. And decide with the exit in mind: a name that geographically or categorically boxes you in ("Dallas Web Design") gets outgrown; the rebrand cost lands later, with interest. Once chosen, the sequence is: register the domain today, file the entity this week (the formation guide), and calendar the trademark decision for when revenue makes the brand worth $350-plus in federal fees.
The Distinguishability Test, in Practice
Every state applies the same rule in the same words, that a new name must be distinguishable on the record from every active entity, and almost nobody outside a filing office knows what an examiner counts. The list is shorter and stricter than founders expect.
These generally do not make two names distinguishable:
- The entity designator. LLC against Inc against Corp against Company. A name is not freed up by changing what comes after it.
- Punctuation and spacing. Commas, periods, hyphens, ampersands and the gap between two words are usually disregarded entirely.
- Singular and plural. One register treats them as the same string; the next may not. Assume they collide.
- Articles. A leading "the" or "a" is normally stripped before comparison.
- Numerals against words. Three against 3 is commonly the same name, and so is second against 2nd.
- Case. Capitalisation carries no weight anywhere.
What does distinguish two names is a different word, or a materially different word order. That is the whole test. It is also worth understanding what the test is not doing: it is protecting the register from ambiguity so that service of process and searches work, not protecting anybody's brand. Two businesses in the same trade with confusingly similar names can both sit on the register happily, and one of them may still lose a trademark dispute to the other.
Trademark law asks a different question with a different answer. Likelihood of confusion looks at sound, appearance, meaning, the goods or services involved and the channels they sell through, so names that are plainly distinguishable on a state register can still be too close for the federal one. This is why clearing the state and stopping there is the expensive error, and why the two searches belong in the same afternoon rather than the same category.
What a Naming Collision Costs: the Risk in Dollars
Clearance is cheap, and every alternative to it is not. The prices below are the reason the sequence on this page is worth an afternoon.
Claiming the name properly. A state name reservation runs about $10 to $50 for thirty to a hundred and twenty days, and it expires. Forming the entity is the claim that does not, at a state fee from $35 in Montana to $520 in Massachusetts. A federal trademark application costs $350 per class of goods or services, so a business selling both a product and a service commonly files two classes at $700.
Not claiming it. A forced rebrand is the largest predictable cost in this article, and none of it is a filing fee. It is new signage, new packaging, reprinted collateral, a new domain bought on the secondary market, vehicle livery, a rebuilt advertising account with none of its history, and every customer who cannot find you under the new name. For a business with premises and vehicles it is routinely a five-figure exercise, and it arrives at the moment the brand has finally become worth something, which is exactly when a registrant notices you.
Changing the legal name later. A legal rename is an amendment filed with the state, plus a fresh bank mandate, updated licences, new insurance certificates and amended contracts. The filing is the cheap part. If only the trading name is changing, a DBA does the same job for far less and leaves the entity alone.
The quiet one. Trademark rights in the United States begin with use, so an unregistered competitor already trading under your name in a territory has rights there whether or not anything was ever filed. That claim does not show up in either database. It shows up in a search engine, which is why the third check on this page exists.
The Naming Mistakes That Get Expensive
Mistake 01: State search only
Why it happensThe state approved it, so it feels cleared.
ConsequenceA trademark holder's letter after the brand has equity: the forced rebrand.
PreventionUSPTO and common-law checks in the same afternoon as the state search.
Mistake 02: Deciding before checking
Why it happensThe perfect name arrives mid-shower, fully formed.
ConsequenceAttachment to an unavailable name, then a compromise chosen under deadline.
PreventionTen candidates through the four checks before ranking any of them.
Mistake 03: Waiting on a reservation that expires
Why it happensThe reservation feels like ownership.
ConsequenceReservations lapse (and Florida has none); the name goes to whoever files.
PreventionForm the entity: filing is the only claim that does not expire.
Mistake 04: Building the brand under a personal name "for now"
Why it happensThe entity can come later, the work cannot.
ConsequenceCommon-law rights and reputation accrue to a name never cleared or claimed.
PreventionClear and claim before the first invoice carries the name.
Mistake 05: Choosing a descriptive name and expecting to own it
The mistakeNaming the business after exactly what it sells, then trying to stop anyone else from doing the same.
Why it happensDescriptive names are easy to agree on internally and look efficient for search.
What it costsTrademark law treats a merely descriptive term as barely protectable until it has acquired distinctiveness, which takes years and evidence. Meanwhile every competitor can describe themselves the same way.
PreventionPush at least two candidates toward the arbitrary or invented end before ranking them. Distinctive names clear crowded registers more easily and are worth defending afterwards.
Three Names, Three Outcomes
The same four checks, run at three different points in the life of a business.
Example 1: Aldergrove Cider LLC, four checks in one afternoon
Ten candidates went through the state register, the federal trademark database, a plain web search and the domain registrars in a single sitting. Six died on the state record, two on existing federal marks in beverages, and one on a small unregistered cidery already trading under it in the next county. One survived.
Outcome: The entity was filed that week and the federal application went in two years later at $350 in one class, once the brand was worth defending. Nothing had to be undone.
Example 2: Marchmont Tutoring LLC, approved by the state and stopped by a mark
The state register was clear, so the founder filed and started building. Twenty-two months later a letter arrived from the holder of a federal registration covering educational services, whose mark predated the LLC by six years. State approval was no defence: the federal registration carried nationwide rights in that class.
Outcome: The rebrand cost signage, printed workbooks, a bought domain and the whole of an advertising account history. The USPTO search that would have prevented it was free.
Example 3: Corvid Print Shop LLC, the name that could be defended
The founder preferred a plainly descriptive name built from the service and the city. Counsel pointed out that such a name would be thin at the USPTO and unenforceable against the four competitors already describing themselves the same way. The invented alternative cleared all four checks on the first pass.
Outcome: Two years on the mark is registered and enforceable. The descriptive version would have cost the same $350 and bought almost nothing.
Clearance first, creativity second, claim immediately
Run every candidate through the state record, the USPTO, the open web, and the domain registrars before falling in love. When one clears all four, register the domain that day and file the entity that week: formation is the claim that lasts.
Frequently asked questions
How do I check if a business name is taken?
Four checks, in order: the state entity database (formation availability, via the name search), the USPTO trademark database (federal rights that override state approval), a web and social search (common-law trademark users), and domain availability. A name is only clear when all four come back workable.
What are the legal requirements for an LLC name?
Three in every state: distinguishable from every entity on the state's record, an entity designator (LLC, L.L.C., or Limited Liability Company), and no restricted words (bank, insurance, university) without regulatory approval. Punctuation and designator differences do not make a name distinguishable. The formation mechanics live in the formation guide.
Does registering my LLC name protect it?
Only within your state's entity records: no other company can register the same name there. It does nothing against a federal trademark holder, who can force a rebrand regardless of your state approval, and nothing in other states. Brand-level protection is the trademark's job: see the trademark guide.
What is the difference between a business name and a DBA?
The legal name is what the state registered at formation; a DBA (doing business as) is a registered alias the same entity operates under. One LLC can hold several DBAs for different brands. DBAs are registrations, not entities: they carry no separate liability protection. See LLC vs DBA.
Should I reserve a business name before forming?
Only when a real gap exists between decision and filing: most states sell reservations ($10 to $50, for 30 to 120 days), but forming the entity is the stronger and often similarly priced claim. Florida offers no LLC reservations at all: filing is the only way to secure a name there.
Can two businesses have the same name in different states?
At the entity-registration level, yes: state records are independent, and identical names coexist across state lines constantly. Trademark law is what crosses borders: whoever holds federal rights (or earlier common-law use in a territory) can stop confusingly similar use in their market regardless of either state's records.
Do I need the exact .com domain?
Need, no; want, usually. The .com still carries default credibility, and email on your own domain is table stakes. When the exact .com is taken, workable patterns are a modifier domain, or a different name: heavy compromise at naming time tends to be regretted at growth time. Check domains in the same pass as the legal checks.
Check the name, then claim it.
Run the state availability check, verify the trademark picture, and secure the name by forming the entity, the only step that actually reserves it permanently.
