Choosing a name for your LLC is one of the most important decisions you will make before filing. However, picking the right name is not enough — your LLC name must be available in the specific state where you plan to form your business. Specifically, if another entity has already registered the same or a confusingly similar name, your Articles of Organization will be rejected and you may need to correct or refile the application; refund rules differ by state.
Furthermore, most entrepreneurs discover this rule too late. They spend weeks building a brand around a name, design a logo, buy a domain, and only then find out the name is already taken in their state. As a result, they either refile under a different name or abandon the process entirely. Therefore, running an LLC lookup — also called an LLC name search or business name search — before doing anything else is the single most effective way to avoid that outcome.
How this free tool works
This free LLC name availability checker routes you to the relevant official state registry. It does not query every registry live or issue a binding name-availability determination. Depending on the portal, you may need to enter the name again; the filing agency makes the final decision.
If you are not sure which state to form in, our complete LLC formation guides cover every state individually, including filing fees, processing times, and compliance requirements. You can also explore all our free LLC tools in one place. In contrast to third-party services that charge for basic searches, everything here is completely free.
LLC name search: official state portals
This tool prepares a link to the state registry. It does not search records here, confirm availability, reserve a name or clear trademarks.
Follow the portal's search instructions. Some links pass the name; others require you to type it again or navigate to the search. A missing match does not guarantee approval. Portal links may change.
How the LLC Name Search Works
Each U.S. state maintains its own database of registered business entities through the Secretary of State's office — or an equivalent agency in states like Wisconsin (Department of Financial Institutions) or Arizona (Arizona Corporation Commission). These records help identify conflicts; the filing agency makes the final name decision.
Select a state to open its official search portal. Search the registry there and review similar names, not only exact matches. Portal features and refresh schedules differ, and a search result is not a reservation or approval.
What "distinguishable" actually means
Every state requires your LLC name to be distinguishable from existing entities in its records. This rule is stricter than most people expect. The following differences are generally not enough to make a name distinguishable in most states:
| What you change | Is it distinguishable? | Example |
|---|---|---|
| Adding "The" at the start | No | The Blue Ridge LLC → Blue Ridge LLC |
| Changing LLC to Inc. or Corp. | No | Maple Farms LLC → Maple Farms Inc. |
| Singular vs. plural | No in most states | River Stone LLC → River Stones LLC |
| Uppercase vs. lowercase | No | APEX LLC → Apex LLC |
| Punctuation differences | No | A&B Services → A and B Services |
| Adding a generic word | Usually no | Summit LLC → Summit Group LLC |
| Adding a location | Often yes | Summit LLC → Summit Denver LLC |
| Adding a unique descriptor | Usually yes | Summit LLC → Summit Digital LLC |
How to search for the best results
To get accurate results from the state database, follow these three tips before hitting search:
Leave out "LLC" at the end
Follow the selected state portal’s instructions for entity designators. Searching with "LLC" included can return incomplete results or miss similar names. Search only the core descriptive words of your desired name.
Try a partial search first
If your desired name is "Riverside Consulting," search "Riverside" first to see all variations. Then search "Riverside Consulting" for exact matches. This two-step approach reveals names you might otherwise miss.
Check inactive entities too
An inactive or dissolved record does not automatically make a name available; release and reuse rules vary by state. Set your search filter to show all entities, not just active ones, to avoid choosing a name that will get rejected at filing.
Name reservation: how to protect your name before filing
If your name is available but you are not ready to file immediately, most states let you reserve it for 30 to 120 days. This prevents another business from registering the same name while you prepare your documents. Fees typically range from $10 to $75 depending on the state. Your registered agent can often handle this step for you if you are using a formation service.
Name Available? Here Are Your Next Steps
Confirming your LLC name is available is the first step — however, there are several important actions to take before and immediately after you file your formation documents. Specifically, skipping any of these can create serious problems down the road that are difficult and costly to fix.
Complete name checklist before filing
What to do if your name is already taken
If the search returns a conflict, you still have several practical options. First, try adding a unique geographic identifier — a location word may or may not make the name distinguishable under your state’s rules. Alternatively, add a specific descriptor that reflects what your business actually does, such as "Summit Digital Marketing LLC." Moreover, you can form your LLC under a different legal name and file a DBA (Doing Business As) to operate and advertise under your preferred name publicly.
Frequently Asked Questions
Is this LLC name availability checker really free?
Yes, completely free. This tool redirects you to the official Secretary of State database for your chosen state. The government search is free and requires no account or signup. We do not charge any fee at any point in the process.
Does an available name in the state database mean my filing will be approved?
Not necessarily. An available name in the search results is a strong indicator, but the Secretary of State makes the final determination when reviewing your Articles of Organization. Names that are very similar — even if not identical — can still be rejected for lacking distinguishability. Additionally, reserved names and recently dissolved entities may not always appear in standard searches.
Should I search with or without "LLC" in the name?
Search without the LLC designator in most states. Follow the state portal’s instructions for suffixes and search modes; try partial core words as well as the complete proposed name. Use only the core descriptive words of your desired name. For example, if your desired name is "Sunrise Consulting LLC," search "Sunrise Consulting." Once you have a name, our LLC punctuation guide shows how to write the designator and whether a comma matters.
Can I use the same LLC name in multiple states?
Yes, but you need to check availability separately in each state. A name that is available in Texas may already be taken in California. If you plan to operate in multiple states, you will need to register as a foreign LLC in each additional state — and your name must be available there too. Some states require you to operate under a different name if your desired name is already taken in that state.
What if my LLC name is available in the state but trademarked federally?
State registration and federal trademark protection are completely separate systems. You can legally form an LLC with a state-approved name and still face a trademark infringement claim if a federally registered mark exists that is confusingly similar. Always run a USPTO trademark search at uspto.gov in addition to the state name search, especially if you plan to expand nationally or build a recognizable brand.
My desired name is taken — what are my options?
You have several practical options. First, try adding a unique geographic identifier — "Summit Denver LLC" is distinguishable from "Summit LLC." Second, add a specific descriptor that reflects what you actually do — "Summit Digital Marketing LLC" vs. "Summit LLC." Third, you can form under a different legal name and file a DBA to operate under your preferred name publicly. Fourth, check if the existing entity is inactive or dissolved — in some states, you can petition to use a dissolved entity's name if it has been inactive for a set period.
How long does an LLC name reservation last?
Name reservation periods vary by state, typically ranging from 30 to 120 days. Most states charge a fee of $10 to $75 for the reservation. Some states allow you to renew the reservation once before you must either file or let it expire. Name reservation is optional in most states — if you are ready to file, it is generally faster to submit your Articles of Organization directly rather than reserving first.
The tool provides navigation to official registries. It does not check trademarks, domain names or legal clearance. Confirm naming rules with the filing agency and check relevant trademark records separately before spending money on a name.
