How to Register a Business Name in 2026: LLC, DBA & Trademark Explained

"Registering a business name" actually means three different things — and most guides conflate them. There is entity registration (LLC/corp), DBA (doing business as), and trademark. Each protects a different thing at a different level.

Here is what each one does and which you actually need.

The Three Ways to Register a Business Name

Method	What It Does	Cost	Protection Level
LLC/Corp registration	Reserves name in your state	$50-500	State only
DBA (fictitious name)	Lets you operate under a different name	$10-150	None — just permission
Trademark	Exclusive rights to the name nationwide	$250-350/class	National, strongest

Method 1: Entity Registration (LLC or Corporation)

When you form an LLC or corporation, your business name is automatically registered with the state. No other LLC in your state can use the same name.

The process:

1. Search your state's business database — every Secretary of State website has a free name search. Your name must be "distinguishable" from existing entities.
2. Check the name rules — most states require "LLC" or "Inc." in the legal name and ban words like "Bank" or "Insurance" without licenses.
3. File formation documents — Articles of Organization (LLC) or Articles of Incorporation (corp) with the state fee.
4. Name is yours the moment the state approves the filing.

Important limitation:

State registration only blocks identical names in that state. Someone in another state can register the same LLC name tomorrow. For real protection, you need a trademark.

Method 2: DBA (Doing Business As)

A DBA — also called fictitious name, trade name, or assumed name — lets you operate under a name different from your legal entity name.

When you need one:

• Sole proprietor "Jane Smith" operating as "Smith Marketing Co"
• LLC "JS Holdings LLC" running a store called "Downtown Coffee"
• Any business using a name that is not its exact legal name

The process:

• File with your county clerk or state (varies by state)
• Cost: $10-150 depending on jurisdiction
• Some states require publishing a notice in a local newspaper (California, New York)
• Renewals every 3-5 years in most states

Critical: a DBA is NOT protection

A DBA is a permission slip, not ownership. It does not stop anyone else from using the name, does not create a legal entity, and does not provide liability protection. It exists so banks can cash checks made out to your trade name.

Method 3: Federal Trademark

A USPTO trademark gives you exclusive nationwide rights to the name for your category of goods/services. This is the only registration that actually stops competitors from using your name.

The process:

1. Search the USPTO TESS database plus Google, social media, and domain availability — a clear search prevents a $350 rejection
2. File at uspto.gov — $250-350 per class of goods/services
3. Wait 8-12 months for examination — the USPTO attorney may issue office actions requiring responses
4. Maintain it — declarations at year 5-6, renewal every 10 years

When a trademark is worth it:

• You are building a brand you will invest in (products, content, ecommerce)
• You plan to expand beyond one state
• The name is distinctive (not "Best Pizza Chicago" — descriptive names are weak marks)

For a local service business with a descriptive name, state registration is usually enough.

The Domain + Social Handle Check

Before registering anything, verify:

• .com availability — or a strong alternative (.co, .io, industry TLD)
• Social handles — Instagram, TikTok, LinkedIn, X, YouTube
• Google the name — existing businesses, negative associations, trademark conflicts

A name you cannot get the .com for will cost you traffic forever. Check everything before filing.

Common Mistakes

• Thinking a DBA protects the name — it does not; anyone can use it
• Skipping the trademark search — launching a brand on a name someone else trademarked means rebranding after you have built equity
• Registering in the wrong state — your home state is correct for 95% of businesses
• Forgetting renewals — DBAs and trademarks lapse; calendar the renewal dates

Frequently Asked Questions

Do I need to register my business name if I am a sole proprietor?

Only if you operate under a name other than your legal name — then you need a DBA. "John Smith Consulting" needs nothing; "Summit Consulting" needs a DBA.

How much does it cost to register a business name?

LLC registration: $50-500 (state fee). DBA: $10-150. Trademark: $250-350 per class. You can do all three for under $1,000 total in most states.

Can two businesses have the same name?

Yes, in different states (state registration) or different industries (trademark). "Delta" is an airline and a faucet company — trademarks are category-specific.

What happens if someone trademarks my business name first?

If you used the name commercially before their filing, you have common-law rights in your geographic area — but expanding becomes legally risky. Search before you launch, not after.

Do I need a lawyer to register a business name?

Not for LLC or DBA — both are simple state filings. For trademarks, DIY works for clean applications, but a $500-1,500 attorney review is worth it for brands you will invest in heavily.

Bottom Line

Form your LLC to register the name in your state, file a DBA if you operate under a different name, and get a federal trademark if the brand matters beyond your state. Check the .com and social handles before you file anything — a great name you cannot own online is not a great name.
