You've chosen your name. Now comes the part that actually makes it yours — registration. This guide walks you through every step: state registration, getting your EIN, filing a DBA, and when you need federal protection. No legal jargon, just what to do and in what order.
Registering a business name isn't a single action — it's a sequence of filings across different government agencies, each serving a different purpose. Most founders get confused because "registering your business" can mean four different things depending on who you ask: forming an LLC, filing a DBA, getting a tax ID, or applying for a federal trademark. This guide covers all four and tells you which ones you actually need.

State Registration vs. Federal Registration: What's the Difference?
Most businesses only need state-level registration. Federal registration is for specific situations — primarily if you want nationwide trademark protection or operate across multiple states under a single identity.
| Factor | State Registration | Federal Registration |
|---|---|---|
| What it does | Creates your legal business entity (LLC, Corp) or reserves your trade name within a state | Grants nationwide trademark rights to your business name in a specific industry |
| Where you file | Secretary of State (or equivalent) in the state where you operate | U.S. Patent and Trademark Office (USPTO) |
| Cost | $50–$300 (varies by state and structure) | $250–$350 per class of goods/services |
| Protection scope | State-level only — another business in a different state can use the same name | Nationwide — exclusive rights across all 50 states in your industry |
| Timeline | 1–5 business days (online); 2–4 weeks (paper) | 8–12 months for standard application |
| Required? | Yes, if forming an LLC or corporation | No — optional but strongly recommended for scalable businesses |
| Enforceability | State courts only | Federal courts; presumption of nationwide ownership |
The simple rule: Register at the state level first. Add federal trademark protection once you know the name is working and you're scaling.
Step-by-Step: State Registration Process
State registration has five distinct steps. Each one builds on the last — don't skip ahead.
Choose Your Business Structure
Your business structure determines which government forms you file and what legal protections you get. The four main options:
Limited Liability Company
Separates personal and business liability. Flexible tax treatment. Best for most small businesses and startups.
C-Corp or S-Corp
Required if you plan to raise venture capital or issue stock. More compliance overhead. C-Corp is standard for VC-backed companies.
Sole Proprietorship
No formal registration required — you operate under your own name. No liability protection. Fine for freelancers testing an idea.
General Partnership
Two or more people operating together. No liability protection by default. A formal partnership agreement is strongly recommended.
Most founders building a real business should form an LLC. It's the simplest structure that provides personal liability protection and doesn't have the compliance overhead of a corporation.
Check Name Availability with Your Secretary of State
Before filing anything, search your state's Secretary of State database to confirm your name isn't already taken. Most states have a free online search tool — just Google "[your state] Secretary of State business name search."
States typically reject names that are identical or confusingly similar to an existing registered entity in the same state. They also block names containing restricted words like "Bank," "Insurance," or "University" without special approval.
If your preferred name is taken in your state, your options are: add a word (e.g., "NamingKit Studio LLC"), use a DBA to operate under a different name while filing the LLC under something else, or check availability in a different state.
Also check at the USPTO trademark database (tess.uspto.gov) before investing in the name — a state filing doesn't protect you from federal trademark infringement claims. See our guide on how to check if a business name is taken for the full multi-database process.
Register with Your State (File Articles of Organization or Incorporation)
Once you've confirmed name availability, file the formation document with your Secretary of State. For an LLC, this is the Articles of Organization. For a corporation, it's the Articles of Incorporation.
Most states now offer online filing through their Secretary of State website. You'll need:
- Your chosen business name (including the required entity suffix — "LLC," "Inc.," "Corp.," etc.)
- A registered agent's name and address in the state (a person or service that receives legal documents)
- Your principal business address
- The names of the organizers or incorporators
- Payment for the filing fee ($50–$500 depending on state and entity type)
After approval, you'll receive a Certificate of Organization (LLC) or Certificate of Incorporation (Corp). This is your official state registration document — store it somewhere safe.
Tip: Delaware, Wyoming, and Nevada are popular states for formation because of favorable business laws, even if you don't operate there. If you form in a state you don't operate in, you'll typically need to also register as a "foreign entity" in your home state (an extra filing and fee).
Get Your EIN from the IRS
An Employer Identification Number (EIN) is your business's federal tax ID — the equivalent of a Social Security Number for your company. You need it to open a business bank account, hire employees, file taxes, and apply for business licenses.
The IRS issues EINs for free through their online application at irs.gov/ein. The process takes about 5 minutes and you receive your EIN instantly upon completion. There's no filing fee — if anyone tries to charge you for this, they're a third-party service adding markup to a free government process.
You can apply for an EIN as soon as your state registration is approved — or even before, since the IRS doesn't require state approval to issue one.
Single-member LLCs can use either the EIN or the owner's Social Security Number for most purposes, but it's best practice to use an EIN to keep personal and business finances clearly separated.
Register a DBA If Operating Under a Different Name
A DBA (Doing Business As) — also called a fictitious business name, assumed name, or trade name — lets your legally registered entity operate under a different name. You need one when your operating name is different from your legal entity name.
Example: If you formed "Smith Consulting LLC" but want to operate as "Bright Path Business Advisors," you'd file a DBA for "Bright Path Business Advisors" under your LLC.
DBA requirements vary by state. Most states require filing with the county clerk or Secretary of State, paying a small fee ($10–$100), and in some states, publishing a legal notice in a local newspaper. The DBA doesn't create a separate legal entity — it's just a name registration.
You can have multiple DBAs under one LLC, which is useful if you run different product lines or brands under the same company.
Important: A DBA is not the same as an LLC name change. It doesn't provide liability protection and doesn't give you trademark rights — it simply allows you to use and advertise under a different name.

Federal registration means filing a trademark application with the U.S. Patent and Trademark Office (USPTO). This is separate from your state LLC registration and is not required to operate a business — but it's the only way to get nationwide name protection.
When You Need Federal Registration
- You operate in multiple states or plan to expand nationally — state registration only protects you within that state
- You're building a brand that's central to your business value (e-commerce, consumer products, SaaS)
- You've chosen a distinctive name worth protecting — coined names and suggestive names are better candidates than descriptive ones
- Investors require it — many VC-backed companies trademark their names as a condition of funding
- You want to license or franchise your brand — trademark ownership is the legal foundation for licensing agreements
How to File a Federal Trademark
- Search the USPTO TESS database (tess.uspto.gov) for conflicting marks in your industry class
- Identify your Nice classification — the international class of goods or services your business operates in (e.g., Class 35 for business services, Class 42 for software)
- File via TEAS (Trademark Electronic Application System) at the USPTO website — the TEAS Plus application costs $250/class; TEAS Standard costs $350/class
- Respond to any Office Actions — a USPTO examining attorney may request clarifications or reject similar marks, and you'll have 3 months to respond
- Publication and registration — approved applications are published for 30 days of public opposition, then registered (total timeline: 8–12 months)

Intent-to-Use applications: You don't have to be actively using your name in commerce to file a federal trademark. The USPTO allows "Intent-to-Use" applications that reserve your name for up to 36 months before you launch. This is useful for locking in a name before your product is live.
5 Common Registration Mistakes to Avoid
A name available in your state can still be trademarked federally by a competitor in another state. Always search the USPTO database before filing state paperwork. A state-approved name doesn't protect you from federal trademark infringement.
If your LLC name and your operating/marketing name are different, you need a DBA. Operating as "Bright Spaces Design" when your LLC is registered as "Jane Smith LLC" without a DBA can void contracts and create banking complications.
Forming an LLC does not give you trademark rights. Your state filing reserves the name within the state business registry — it doesn't prevent someone else from using the same name commercially across the country. These are completely different filings with different agencies.
The USPTO regularly rejects purely descriptive names because they describe a quality of the product rather than serving as a brand identifier. "Quick Clean Laundry LLC" will pass state registration but will struggle at the USPTO. Read our guide on brand vs. descriptive names before committing to a name style.
If you're formed in Delaware but have employees or offices in California and New York, you need to register as a foreign entity in those states too. Each additional state typically costs $100–$300 and may have annual report requirements. Skipping this can result in fines and void legal protections.
Start With a Name Worth Registering
The registration process is straightforward — the hard part is choosing a name that's distinctive enough to protect and memorable enough to build a brand around.

Frequently Asked Questions
How much does it cost to register a business name?
State registration fees range from $50 to $300 depending on your state and business structure. LLC formation typically costs $50–$500 in filing fees; a DBA (doing business as) registration costs $10–$100. Getting an EIN from the IRS is completely free. Federal trademark registration costs $250–$350 per class of goods or services. Budget $100–$600 for a standard state registration and $350–$700 if you also want federal trademark protection.
Do I need to register my business name federally?
Most small businesses only need state registration. Federal registration is required if you operate across multiple states and need nationwide name protection, or if you want federal trademark protection. Registering federally with the USPTO as a trademark is optional but gives you exclusive nationwide rights to the name in your industry, the ability to sue infringers in federal court, and a legal presumption of ownership. State registration alone only protects you in the states where you're registered.
What is the difference between an LLC and a DBA?
An LLC (Limited Liability Company) is a legal business structure that separates your personal assets from business liabilities and registers a primary business name with the state. A DBA (Doing Business As), also called a fictitious business name or trade name, lets you operate under a different name without changing your legal structure. For example, "Jane Smith LLC" (the legal entity) might operate as "Bright Spaces Interior Design" (the DBA). You can have multiple DBAs under one LLC. DBAs do not provide liability protection — that comes from the LLC itself.
Can two businesses have the same name in the same state?
Generally no — state Secretary of State offices reject new registrations that are identical or confusingly similar to existing registered names in the same state. However, two businesses in different states can share the same name, and a DBA name might not be checked against the LLC database in all states. To get true nationwide exclusivity, you need a federal trademark registration with the USPTO. State registration only protects you within that state's filing system.
How long does it take to register a business name?
State online registrations are typically approved in 1–5 business days; some states (like Delaware) process in 24 hours. Paper filings can take 2–4 weeks. DBA registrations are usually same-day to 1 week. An EIN from the IRS is issued instantly when you apply online at IRS.gov. Federal trademark registration takes 8–12 months for a straightforward application. Expedited options exist in many states for an additional fee.
