Key Takeaways
- Start with your state’s Secretary of State business entity search. It decides whether your LLC or corporation name can be filed.
- A business name cleared at the state level can still infringe on someone’s trademark, so search the USPTO database as well.
- Check domains and social handles before you commit to any business name. They are part of your brand even though they aren’t legal filings.
- Search DBAs and “doing business as” names at the county or state level. Many businesses operate without forming an entity.
- If your name is available, reserve it or file right away, because availability isn’t guaranteed to last.
Learn how to check if a business name is available using state databases, trademark searches, DBA records, domain names, and social media before registering your business.
Whether you are starting a sole proprietorship or an LLC, you need a business name that fits your brand and meets your state’s naming rules. But before you print business cards, buy a domain, or file your paperwork, it is important to choose whether the name is already in use.
A business name search usually takes about 20 minutes and can help you avoid rejected filings, costly rebranding, or potential trademark conflicts. This guide walks you through the right places to search, in the right order, to ensure your chosen name is available before you register or start your business.
How to Check If a Business Name Is Available in 6 Simple Steps
Step 1: Search Your State’s Business Entity Database
If you are forming an LLC or corporation, checking your state’s business entity database is an important first step. States generally require these entities to have names that are distinguishable from existing registered businesses. If your proposed name doesn’t meet the state’s naming rules, your formation filing may be rejected. Most states offer a free online search through the Secretary of State or an equivalent filing office, although some may charge a fee.
How to run the search to check if a business name is available:
- Go to your state’s business entity search page.
- Enter your exact proposed name with or without the required designator.
- Review the results for identical or similar names.
- Search again with variations (plural forms, abbreviations, with and without spaces, and alternate spellings).
What to look for:
- Exact matches: Active LLCs and corporations with the same or a very similar name. If the business name is taken, you can’t use it for the same entity type in that state.
- Reserved names: Look for the reserved name that another filer is holding.
- Near matches. Names that differ only by punctuation, “LLC” versus “Inc.”, or small word changes are often treated as the same name.
- Inactive or dissolved entities. Some states free up a name when an entity is dissolved, while others keep it unavailable for a period. Check your state’s rules.
TIP: States require names to be "distinguishable in the records." That means adding "LLC," changing punctuation, or swapping a number for a word usually does not count as unique.
Business Name Search by State: Official Search Portals
As we said, there’s no single official national database for checking business name availability. Instead, each state maintains its own business entity search portal, usually through the Secretary of State or an equivalent agency. Use the links below to access your state’s official government portal and check whether your proposed business name is available.

NOTE: Portals sometimes move, so if a link has changed, start from your state's Secretary of State homepage and look for "Business Search" or "Entity Search."
Step 2: Run a Federal Trademark Search (USPTO)
A state search only covers your state, but trademarks work nationwide. Search the USPTO’s trademark search system for your name and similar-sounding or similar-looking names.
What counts as a conflict: The question isn’t whether the names are identical; it’s whether a customer could be confused. A mark in a related industry that sounds or looks similar can be a problem even if the spelling differs. A similar mark in a completely unrelated industry usually carries less risk, but the analysis can be nuanced.
If you find a close match, consider choosing a different business name, or speak with a trademark attorney before you proceed. Once you have cleared a name and want to protect it, you can start trademark registration to claim nationwide rights.
Step 3: Search for DBAs and Unregistered Names
Not every business is registered as an LLC or corporation. Sole proprietors and partnerships often operate under a “doing business as” name filed with a county clerk or state office, so a business name can be in use without appearing in your Secretary of State search.
So, check your county clerk’s records and your state’s fictitious name database. If you plan to operate under a name other than your legal name, you will likely need to file a DBA yourself or hire a professional to file a DBA on your behalf.
Step 4: Check Domain and Social Media Availability
Domain and social handles aren’t legal registrations, but they affect how easily customers find you.
- Domain: Search for the exact business name as a .com. If it’s taken, decide whether an alternative such as .co, .net, or a slight variation still works for your brand.
- Social media: Check Instagram, Facebook, TikTok, LinkedIn, X, and YouTube for the exact name and clean variants. Claim handles even on platforms you will not use yet, so nobody else takes them. If the exact handle is taken, look at who owns it: a dormant account is a different situation than an active competitor.
Step 5: Do a General Web Search
Finally, search Google, Yelp, and Yahoo for your chosen business name, and for your name with your industry or city. Look for:
- Businesses using the name without any formal registration.
- Similar names in your market.
- Negative associations (a name with an unfortunate meaning or a bad reputation attached).
Unregistered businesses can still have “common law” rights where they operate, so this search catches conflicts the databases miss.
Quick Reference: Where to Check Name Availability
Where to Search | What It Tells You | Cost |
State business entity database | Whether your LLC or corporation name can be filed | Usually free |
USPTO trademark search | Whether the name conflicts with a federal trademark | Free to search |
County/state DBA records | Whether a “doing business as” name is in use | Usually free |
Domain registrar | Whether the website address is available | Free to search |
Social media platforms | Whether the handle is available | Free |
Google search | Whether unregistered businesses use the name | Free |
What If the Business Name You Want Is Taken?
Don’t abandon the idea yet. You have options:
- Add a distinguishing word: “Summit Landscaping” becomes “Summit Ridge Landscaping.” Make sure the change is meaningful and not just punctuation.
- Add a location or descriptor: Something like “Summit Landscaping of Denver” can make the name distinct, but check how your state treats such additions.
- Choose a different name: If the name is trademarked or heavily used in your industry, moving on is usually safer than fighting over it.
- Contact the owner: Occasionally a business holds a name it no longer uses, and you can negotiate to acquire it, but this is rare.
Avoid tricks like swapping a letter for a number or adding an extra space. State offices and trademark examiners look past cosmetic changes, and so do customers.
What to Do After You Confirm Your Chosen Business Name Is Available?
Once you have confirmed that your preferred business name is available, the next step depends on how soon you plan to start your business and which business structure you choose.
- Reserve the name: If you are not ready to register your business yet, check whether your state allows you to reserve the name for a specific period. You will usually need to submit an application and pay a fee.
- Register your business: If you are ready to get started, file the required formation documents with the state for your LLC or corporation. If you are a sole proprietor, check whether you need to register a DBA or trade name.
- Protect your name: Register your domain, claim your handles, and consider trademark registration.
Remember, reserving or registering a business name with the state doesn’t automatically give you federal trademark rights. A separate trademark search can help you identify potential conflicts before you invest in branding and marketing.
Why Checking Business Name Availability Matters
A business name is a legal identifier, a brand asset, and a search term all at once. Getting it wrong causes three kinds of problems.
- Your filing can be rejected. Every state requires a new LLC or corporation name to be distinguishable from the names already on file. If yours is identical or too similar, the filing office will return it. You’ll lose time and may need to refile.
- You can face trademark claims. Registering a name with the state doesn’t give you trademark rights, nor does it protect you from someone who already holds them. If your name is confusingly similar to a registered or pending mark in a related industry, the owner can demand that you stop using it. That can mean a costly rebrand after you’ve built your customer base.
- You can confuse customers. Even without legal trouble, a name that closely resembles a competitor’s splits your search traffic and makes you harder to find online.
Common Mistakes to Avoid While Choosing a Business Name
- Only searching one place. A state search alone won’t reveal trademark conflicts, and a trademark search alone won’t tell you whether the state will accept your filing.
- Assuming “available” means “safe.” A business name can be open in your state’s database and still infringe on a mark owned by someone else.
- Searching only the exact spelling. Similar names are what get filings rejected and cause customer confusion.
- Ignoring the domain. A great name with no matching website address is harder to market.
- Waiting too long. If you have found a good name, file or reserve it before someone else does.
Conclusion
Checking whether a business name is available means searching multiple places: your state’s entity database, the USPTO trademark register, DBA records, domains, social media, and the open web. Do all five checks before you file, and you will avoid rejections, legal trouble, and an expensive rebrand later.

FAQs
Search your state’s Secretary of State business entity database first, then run a federal trademark search on the USPTO website. After that, check domain names, social media handles, and DBA records, and finish with a general web search.
In most cases, yes. Most state business databases, the USPTO trademark search, domain lookups, and social media checks are free to use. A few states charge a small fee for certain searches or name reservations.
Within one state, two LLCs or corporations generally can’t register the same name. But unregistered businesses, businesses in other states, and businesses in unrelated industries may use similar names, and trademark rights can still apply across state lines. That’s why checking several sources matters.
It protects the name at the state level, preventing other entities in that state from registering it. It doesn’t give you trademark rights or stop others from using a similar name elsewhere. For wider protection, you’d need to register a trademark.
It depends on the state. Reservation periods vary, and some states let you renew. Check your Secretary of State’s website for the exact length and fee.
If it’s already registered in your state, your filing will likely be rejected. If it infringes a trademark, you could receive a cease-and-desist letter, be forced to rebrand, or face legal action. Checking first is far cheaper than fixing it afterward.
Yes. A DBA also has to be distinguishable from other names on file in many places, and you can still run into trademark issues. Search your state or county records before filing.
A sole proprietorship does not require forming a separate entity, so you can operate under your own legal name without a state filing. If you want a different trade name, you typically register a DBA with the county or state. Check the same places: your county clerk or state assumed-name registry, the state entity database (so you do not trade under an existing LLC's name), the USPTO, and the web.
