How to Search and Register Your Business Name: State, Federal, and Domain
Registering a business name that someone else already owns — legally or as a trademark — is a mistake that can cost thousands to fix. Running the right checks before you file takes 30 minutes and prevents years of headache. Here is the exact sequence.

The Quick Answer
Before you register anything, run three searches in this order: 1. Your state's business name database. 2. The USPTO federal trademark database. 3. Domain registrar search. All three must come back clear before you commit to a name. Then register your LLC or DBA with your state and secure the domain on the same day.
The Three Searches You Must Run
State business database: Every state maintains a searchable database of registered business names. Go to your Secretary of State website and search your exact desired name plus obvious variations. A name is typically unavailable if it is identical or confusingly similar to an existing entity in your state.
USPTO Trademark Electronic Search System (TESS): Go to tess.uspto.gov and search for your name in your industry category. A federally registered trademark gives the holder the right to stop you from using the name nationally, even if you registered your LLC first.
Domain search: Check Namecheap or Google Domains for your .com and obvious variations. The domain search also shows you whether another business is already operating under that name online.
LLC Name vs DBA vs Trademark
LLC name: Your LLC's legal name registered with your state. Gives you the right to use the name within that state. Does not protect you nationally.
DBA (Doing Business As): A fictitious business name that lets you operate under a different name than your LLC. Required if your LLC is 'Smith Holdings LLC' but you operate as 'Bright Bakery.'
Trademark: Federal registration through the USPTO. Gives you nationwide rights to use the name in your industry category. Costs $250-$350 per class to file. Takes 8-12 months. Worth it if your brand name is a significant business asset.
When to File a DBA
File a DBA (also called a fictitious business name or assumed name) when you want to operate under a name different from your LLC's legal name. This is common when the LLC name is generic (like your own name) and you want a branded operating name. DBA registration costs $10-$100 at your county clerk's office and requires periodic renewal.
When to File a Federal Trademark
File a trademark when: your brand name is a meaningful business asset, you operate or plan to operate in multiple states, you are in a competitive market where name confusion could redirect customers to competitors, or you plan to franchise or license the brand. Do not trademark a name you have not yet used in commerce — file an intent-to-use application if you are still building.
The Verdict
Run all three searches before you file anything. Register the LLC and the domain on the same day once you confirm availability. File a DBA if you need a different operating name. File a trademark when the brand is worth protecting — typically once you have revenue and customers who know the name.
How to Get Started
Start with your state Secretary of State business search. Then search tess.uspto.gov. Then check Namecheap for the .com. If all three are clear, file your LLC with a formation service, register your domain the same day, and handle DBA registration at your county clerk if needed.

FREQUENTLY ASKED QUESTIONS
What if my name is available in my state but there is a similar trademark?
You can still register the LLC, but using the name in commerce may infringe on the trademark holder's rights. Consult a trademark attorney before proceeding if there is a similar federal trademark in your industry.
Do I need to register my business name in every state?
You register your LLC name in your state of formation. If you register as a foreign LLC in other states, you may need to register the name there too. A DBA is registered at the county or state level where you operate.
How long does a business name registration last?
LLC registrations are typically perpetual as long as you file annual reports and pay any required fees. DBA registrations often expire every 3-5 years and must be renewed. Trademarks last 10 years and can be renewed indefinitely.
