To find out if an LLC name is already taken, run a free search of your state’s business entity database, usually hosted on the Secretary of State’s website. That search takes a few minutes and tells you whether another registered entity in the state is already using the name. A complete check goes further: the federal trademark registry, local county filings, and domain availability all affect whether the name is actually safe to use.
Search Your State’s Business Entity Database
Each state maintains a searchable database of registered business entities. Most sit on the Secretary of State’s website, though a few states run them through a Department of Commerce or Division of Corporations. The search is free and generally requires no account. The database covers corporations, LLCs, limited partnerships, and other formal entities registered in that state.
Look at the status column in your results. A business marked “active” or “in good standing” means the name is off limits. A “dissolved,” “withdrawn,” or “inactive” result doesn’t automatically free the name up, because some states hold dissolved names in reserve for a period or allow the original owner to reinstate. No results at all usually means the name is available to file.
Run partial searches, not just the exact name you want. Most state databases offer a “starts with” or “contains” filter. Searching the first two or three distinctive words catches variations an exact match would miss, like plural forms or different entity suffixes. Try several versions, including common misspellings, so you see everything on file that resembles your name.
Understand What “Distinguishable” Means
States don’t just require your name to be different. They require it to be “distinguishable on the records” of the filing office, and that standard is narrower than most people assume. Superficial differences usually fail. In most states, each of the following won’t make a name distinct from an existing one:
- Swapping the entity suffix, so “Apex Consulting LLC” and “Apex Consulting Inc.” are treated as the same name.
- Adding or removing punctuation like periods, commas, hyphens, or ampersands.
- Singular versus plural, so “Golden Oak Design” and “Golden Oak Designs” are the same.
- Capitalization, formatting, or stylized lettering.
- Adding “The” at the start or switching “and” for “&”.
Your name needs at least one meaningfully different word, or a word arrangement that changes the overall impression. A minor tweak intended to slide past a similar filing will almost certainly be rejected.
Search the Federal Trademark Database
A name being available at the Secretary of State does not mean it’s safe from a trademark claim. Trademark law runs on a separate track from business entity registration, and a name that clears the state database can still infringe someone’s federal trademark. This is where many new owners run into expensive trouble.
The USPTO maintains a free trademark database at tmsearch.uspto.gov covering active and pending federal registrations. The older TESS system was retired in late 2023 and replaced with this tool. Don’t limit yourself to exact matches. Search for phonetically similar marks (names that sound alike but are spelled differently) and visually similar ones, because trademark law looks at the overall impression on consumers, not identical spelling.
Check whether a matching trademark covers goods or services related to your business. Trademark rights are tied to specific categories of commerce. A “Brightpath” mark registered for software consulting doesn’t necessarily block a “Brightpath” LLC selling landscaping supplies. But if there’s any overlap in industry or customer base, you’re walking into litigation risk. When you spot a potentially conflicting mark, talking to a trademark attorney before filing is cheaper than responding to a cease-and-desist after you’ve printed business cards.
Check for Unregistered and Local Uses
Federal and state databases won’t catch every conflict. Businesses can acquire trademark rights just by using a name in commerce, without filing anything. These “common law” rights exist from the moment a business uses a distinctive name to sell goods or services, and they’re enforceable in court even against a later-registered LLC.
Common law rights are limited to the geographic area where the business actually operates. A small bakery in one city using an unregistered name can’t stop you from using it three states away. But if you’re in the same market, or plan to expand into theirs, the earlier user has priority. There’s no central database for this. Run thorough internet searches, check social media, and look through industry directories for businesses using similar names in your space.
State databases also skip “Doing Business As” (DBA) and fictitious business name filings, which are registered at the county level through the county clerk or recorder. A sole proprietor operating under a trade name won’t show up in your state search, but they may have a legitimate local filing that predates your LLC. This matters most if your business will serve a local market or run a physical location. Many counties offer online search tools for fictitious name records; some still require an in-person or phone inquiry.
Check Domain and Social Media Availability
A name can be legally available and still practically unusable if someone else holds the matching domain or social handles. Before locking in your choice, check whether the .com (and any other extensions relevant to your industry) is available through a domain registrar, and search the major social platforms for matching usernames.
Coordinating your legal name, domain, and social handles from the start avoids the situation where your LLC is registered under one name but your online presence uses a variation. Customers notice the inconsistency. If the .com is held by an active business, adjusting your name to something with an available domain is easier and cheaper than trying to pry it loose later.
Watch for Restricted Words
Even a name that’s unique can be rejected if it includes a word the state restricts. “Bank,” “trust,” “insurance,” “credit union,” and “savings” are restricted in most states because they imply a regulated financial institution. Using any of them typically requires written approval from the state’s banking or financial services regulator before the Secretary of State will process your filing.
Other commonly restricted terms include “university,” “college,” “attorney,” and “architect,” which suggest licensed professional services. If your LLC actually provides those services, you may need to form a Professional LLC rather than a standard one. Before you file, check your state’s naming statute for its specific list of restricted words. If your preferred name includes a financial or professional term and you don’t hold the required license or approval, pick a different name.
What to Do if the Name Is Taken
If your first choice is unavailable, you have a few options depending on the situation:
- Modify the name by adding a meaningful word (not just an article or a different suffix). “Brightpath Consulting” and “Brightpath Digital” are different enough in most states.
- Contact the existing owner. If the conflicting business is dissolved or inactive, some states let you use the name after a waiting period. If it’s active, you can try to negotiate a transfer or purchase, though the other party has no obligation to agree.
- File a DBA once your LLC is formed. Your LLC’s legal name stays one thing, and you operate publicly under a different fictitious or trade name.
- Start over with a new name that’s clear across the state database, the trademark registry, and domain availability all at once.
Whichever route you take, run the full search process again on any new candidate before filing.
Reserve the Name Once It’s Clear
When your search confirms the name is available but you aren’t ready to file your Articles of Organization yet, you can hold the name by submitting a name reservation application. This is useful while you finalize your operating agreement, secure funding, or line up a registered agent.
Fees vary by state and generally run $10 to $50, with a few states charging up to $100. The reservation holds the name for a set period, most commonly 60 to 120 days. Some states allow extensions; others require a short gap before you can reserve the same name again. If the reservation expires before you file, the name goes back into the public pool. Most states let you file the reservation through the same online portal where you ran your search, though a handful still require a mailed paper form with a check. A reservation is not the same as forming the LLC. It holds your place in line until you file.
