LLC name search, by state
Checking whether an LLC name is available looks like a single step — type the name into a state database and see if it comes back clean. In practice it is four overlapping searches across four different systems, each of which can block a name the others cleared. The state entity database settles the legal name. Trademark, domain, and social handles settle whether the name is actually usable. A name is only truly free when it survives all four.
This is informational, not legal advice. Search rules and database tools differ by state and change over time; the relevant Secretary of State office is the authority for any single state in 2026.
Where to search: the state entity database
Every state maintains a free, public business-entity search run by the Secretary of State or an equivalent office (Corporations Division, Department of State, or similar). It is the system of record for entity names, so it is the first and most important place to look. The search covers LLCs, corporations, limited partnerships, and any names already reserved — all of which a new LLC name has to be distinguishable from.
The mechanics are similar everywhere. Search the distinctive part of the name without the designator: searching “Riverstone” rather than “Riverstone Consulting LLC” surfaces near matches the exact-phrase search would miss. Most databases support a starts-with or contains search; using the broader option catches collisions that a strict match hides.
How the distinguishable standard works
State approval turns on whether the proposed name is distinguishable upon the records from existing ones. That is a mechanical test, not a judgment about customer confusion. Two names can look confusingly similar to a person and still be “distinguishable” to the state, or look different to a person and fail.
| Change to an existing name | Usually distinguishable? |
|---|---|
| Swapping the designator (LLC vs. Inc.) | No |
| Adding or dropping "the," "a," or "an" | No |
| Changing punctuation or spacing | No |
| Singular vs. plural of the same word | No |
| Replacing "and" with "&" | No |
| Adding a distinctive (non-generic) word | Often yes |
| A genuinely different distinctive word | Yes |
The practical takeaway: if the only daylight between a proposed name and an existing one is punctuation, an article, or the entity suffix, the filing is likely to be rejected. The name needs a real, distinctive difference.
It also helps to know that the standard is applied across all entity types on the state’s books, not just other LLCs. A proposed LLC name can collide with an existing corporation, a limited partnership, a nonprofit, or a name another filer has reserved but not yet used. That is why a search has to look broadly — checking only for matching LLCs misses the corporation or reserved name that will block the filing just as effectively.
Reading the search results
A database search rarely returns a clean yes or no. It returns a list, and the judgment is in reading it. A handful of points make the results more useful:
- Check entity status. An exact match held by an active entity is a hard block; the same name on a dissolved, expired, or administratively terminated entity may be available, because a name that is no longer protected can be reclaimed.
- Look past the designator. The system ignores the LLC/Inc. suffix when judging distinguishability, so a search should too — treat “Summit Group Inc.” as a potential conflict for “Summit Group LLC.”
- Watch for near-spellings. Slight spelling variants and singular/plural forms of the same root word are the matches most likely to be deemed not distinguishable.
- Note reserved names. A name on hold for another filer shows up even though no active entity uses it; it is still off-limits until the reservation lapses.
Beyond the entity name: trademark, domain, social
The state database is necessary but not sufficient. Three more searches decide whether a cleared name is worth using.
Trademark. A federal trademark can bar a name in commerce even when a state registers the LLC without complaint, and trademark rights are national rather than state-bound. A free search of the U.S. Patent and Trademark Office (USPTO) database flags registered and pending marks in the same or similar names. This is the search most likely to surface a problem the entity database never would, and it is the one where professional clearance matters most for a name a business plans to build a brand on.
Domain. A matching web address should be checked early through any domain registrar. A state-approved name with no usable domain forces a compromise after the fact, so confirming the domain before filing keeps the brand consistent.
Social handles. The same name across the major platforms is worth a quick check for the same reason — a consistent handle is far easier to secure before the name is locked than to retrofit later.
These four searches answer four different questions, and it helps to keep them straight:
| Search | Question it answers | Cost |
|---|---|---|
| State entity database | Can the LLC legally register this name here? | Free |
| USPTO trademark | Can someone bar the name in commerce? | Free to search |
| Domain registrar | Is a matching web address available? | Free to check |
| Social platforms | Are matching handles open? | Free |
The entity search is the only one that gates the legal filing; the other three gate whether the name is worth building on. A name can pass the state database and fail every other check — which is exactly why all four matter before the name is final.
What “available” does and does not guarantee
A clean state search is a strong signal, not a verdict. It does not guarantee the name will be approved — the clerk processing the formation makes the final distinguishability call and may read a near match more strictly than the public tool suggests. It does not guarantee freedom from trademark claims, which live in a separate federal system. And it does not reserve the name; until the formation document is filed or a reservation is placed, another business can claim the same name first.
Conversely, a name appearing in the database is not always a hard block. An entity that is dissolved, expired, or in a status that frees its name may no longer protect it, and some states release names after a dormancy period. When a desired name is taken by an inactive entity, the state office can confirm whether it is genuinely available.
Why the same name can be available and unavailable at once
It surprises many first-time filers that a name can be genuinely “available” in one sense and blocked in another at the same moment. The state database, trademark law, and domain registration are three separate systems with three separate owners, and none of them talks to the others. A name can be free on the state record (no conflicting entity), claimed in trademark (another business holds the mark), and taken as a domain (someone registered it years ago) all at once. Availability is not one fact; it is a stack of independent facts that each have to come back clear.
This is also why the order of the searches matters. The state database is checked first because it is decisive for the legal filing — but it is checked early precisely so a filer does not invest in branding around a name that the trademark or domain check will later kill. Discovering a trademark conflict after the LLC is formed and the website is built is far more costly than discovering it during a five-minute search beforehand.
Reserving a name once it clears
When a name passes all four checks but formation is still weeks away, most states allow a name reservation — a hold that blocks others from claiming it. Reservation typically costs around $10 to $50 and lasts 30 to 120 days depending on the state, sometimes renewable. For an LLC forming immediately, the reservation is usually skipped because the formation filing claims the name directly.
Common reasons a name gets rejected
- Not distinguishable — too close to an existing or reserved name under the mechanical test above.
- Missing or wrong designator — the legal name omits LLC / Limited Liability Company or uses a form the state does not accept.
- Restricted words without approval — bank, insurance, university, or licensed-profession terms used without the required regulator sign-off.
- Prohibited words — terms implying a government agency or otherwise barred by the state.
- A reserved name — the name is on hold for another filer even though no active entity uses it yet.
A quick step list
- 1. Search the state database on the distinctive part of the name, using a contains search.
- 2. Apply the distinguishable test — confirm the difference from near matches is real, not just punctuation or a designator.
- 3. Run a USPTO trademark search for registered and pending marks in the same name.
- 4. Check the domain and social handles for consistency.
- 5. Reserve or file — reserve if formation is weeks off, or file the formation document to claim the name now.
Frequently asked questions
Where do I search to see if an LLC name is taken?
Use the state's free business-entity search, run by the Secretary of State or equivalent office. It is the system of record for entity names and the first place to check. Search the distinctive part of the name without the designator to surface near matches.
Does a state name search tell me if a trademark conflicts?
No. The entity database only covers names registered in that state. Trademark rights are federal and live in the separate USPTO system, so a free USPTO search is a distinct step that often surfaces conflicts the entity search never would.
If a name shows up in the database, is it always off-limits?
Not necessarily. An entity that is dissolved, expired, or in a status that releases its name may no longer protect it, and some states free names after dormancy. The state office can confirm whether a name held by an inactive entity is available.
Does an available name mean my filing will be approved?
A clean search is a strong signal but not a guarantee. The clerk processing the formation makes the final distinguishability call and may read a near match more strictly than the public tool. Approval is confirmed only when the filing is accepted.
How do I lock a name before I file?
Most states allow a name reservation that holds the name for others. It typically costs around $10 to $50 and lasts 30 to 120 days depending on the state. For an LLC forming right away, the formation filing claims the name without a separate reservation.
Should I check the domain before or after the state search?
Check the domain and social handles early — ideally alongside the state search. A state-approved name with no usable domain forces a brand compromise later, so confirming availability before the name is finalized keeps everything consistent.
