How to Choose a Name for Your LLC
Choosing an LLC name means satisfying three separate checks: your state's naming rules, which require an LLC designator and a name distinguishable from other registered businesses; a federal trademark search, which your state doesn't perform for you; and practical availability, such as a matching domain name. Clearing your state's check only means the state will approve your filing, not that the name is free of trademark or branding conflicts elsewhere.

Comprehensive Guide
Follow Your State's LLC Naming Rules
Every state requires your LLC's legal name to include a designator showing it's a limited liability company, such as "LLC," "L.L.C.," or the full phrase "Limited Liability Company," and some states accept additional variants like "Limited Company" or "LC." The name must also be distinguishable from every other corporation, LLC, and limited partnership already on file with that state's filing agency; two names that differ only by punctuation, spacing, or a word like "the" are usually treated as the same name and will be rejected.
Search Your State's Business Entity Database
Before you settle on a name, search your state's free online business entity database to confirm no one has already registered it. Do this early, since discovering a conflict after you've ordered a logo, built a website, or printed materials is far more costly than checking first.
Search the USPTO Trademark Database Before You Commit
Your state's name check only looks at other businesses registered in that state; it has no connection to federal trademarks. Search the United States Patent and Trademark Office's trademark database for your proposed name and any close variations before you commit to it, especially if you plan to use the name as a product or service brand beyond your LLC's legal registration. A name can pass your state's check and still expose you to a trademark infringement claim from a business registered elsewhere.
Watch for Words That Require Extra Approval
Some words trigger additional review in certain states because they imply a regulated activity or a government affiliation. New York, for example, publishes a specific list of restricted and prohibited words and phrases, requiring sign-off from another state agency before the name can be approved, according to the New York Department of State. Words implying banking, insurance, or a government connection are common examples across states generally; check your own state's specific list rather than assuming a word is fine.
Check Domain and Social Media Availability
Your state's approval has nothing to do with whether a matching website domain or social media handle is available. If an online presence matters to your business, check domain availability and your preferred social platforms before finalizing the name, since a perfect legal name with no matching domain can mean building your brand around a different, less direct web address.
Reserve the Name if You're Not Ready to File
If you've settled on a name but aren't ready to file your Articles of Organization, most states let you reserve the name for a fee, typically for 60 to 120 days depending on the state, which keeps anyone else from registering it in the meantime. This is useful if you're still finalizing a business plan, waiting on funding, or coordinating a launch date.
Practical Considerations
A State Check and a Trademark Search Protect Against Different Risks
Treat these as two separate steps, not one. Your state's check determines whether you can legally file and register the LLC under that name. A trademark search determines whether using that name, especially as a public-facing brand, risks a legal claim from someone who registered it federally first, even in a different state. Clearing one doesn't clear the other.
Your LLC's Legal Name Doesn't Have to Match Your Brand Name
Many businesses operate under a brand name that differs from their LLC's legal name, using a DBA ("doing business as") filing to do so legally. This gives you flexibility: you can register a straightforward, compliant legal name with the state while using a more marketable brand name for customers, as long as the DBA is properly filed where required.
Restricted Words Can Delay Your Filing
If your chosen name includes a word that requires extra approval, your filing can take significantly longer while the state routes it to another agency for sign-off, or it may be rejected outright if you don't have the required license or authorization. Check your state's specific restricted-word list before you file, not after a rejection notice arrives.
Think Beyond Today's Business Plans
A name that's too narrowly tied to one product or service can box you in if the business grows or pivots. Consider whether the name still makes sense if you expand your offerings later, since a full legal name change later means a new state filing fee and updating every license, contract, and account that references the old name.

Frequently Asked Questions
What words are restricted when naming an LLC?
Rules vary by state, but words implying a regulated activity, such as banking or insurance, or a government affiliation commonly require extra approval. New York publishes a specific list of restricted and prohibited words and phrases, according to the New York Department of State; check your own state's list before filing.
Does my LLC's legal name have to match my website domain?
No. Your state's approval only concerns the legal name on file; it has no connection to domain availability. Many businesses use a DBA to operate under a different, more marketable name while keeping a separate legal name registered with the state.
Can I reserve an LLC name before I'm ready to file?
In most states, yes. States typically let you reserve a chosen name for a fee and a set period, commonly 60 to 120 days, which prevents another business from registering it while you finish preparing your Articles of Organization.
If my state approves my LLC name, does that mean it doesn't conflict with a trademark?
No. Your state only checks the name against other businesses registered in that state; it doesn't search the USPTO's federal trademark database. Search the USPTO's database separately before committing to a name you plan to use as a brand.
