To register my business name in the US, you need to search your state database and the USPTO trademark system to confirm availability, choose a legal structure, file with your state agency, add a DBA if needed, appoint a registered agent, and apply for an EIN. Filing online gets most registrations done within one to three business days. Skipping any of these steps can mean filing under a name someone else already owns, or choosing a structure that forces you to re-file later at extra cost.

The process has two distinct paths: one for sole proprietors who just need a trade name on file, and one for founders forming an LLC or corporation. Which path you take changes where you file, what you pay, and how much legal protection your name actually gets. This guide walks you through each step in order so you don't backtrack.

Is Registering a Business Name the Same as Forming an LLC?

No. These are two different legal acts, and confusing them is one of the most common mistakes new founders make.

Registering a business name, on its own, puts a name on record. It does not create a separate legal entity. A sole proprietor who files a "doing business as" (DBA) name with their county clerk has a registered name, but the business and the owner are still the same legal person. If the business gets sued, personal assets are exposed.

Forming an LLC or corporation is different. You are creating a new legal entity that owns the business name as part of its formation. The name gets registered automatically when the entity is formed, and the liability separation between you and the business becomes real from that point forward.

The practical question is: do you need name protection only, or do you need the legal structure that comes with an LLC? If you are testing a side project under a trade name, a DBA may be enough to start. If you are taking on clients, signing contracts, or hiring anyone, forming an LLC is worth doing from day one.

For a detailed walkthrough of the entity formation side of this process, the guide on key steps to form an LLC covers what to file, in what order, and what to watch for at each stage.

Step 1: Check Whether Your Business Name Is Available

Before you file anything, you need to confirm the name is actually free to use. One search is not enough. Run all three of the following checks before you spend time or money on registration.

1. Search your state's business name database.
Every state maintains a searchable registry of active business names and entities. Go to your Secretary of State's website (or the equivalent agency in your state) and search the exact name you want, plus close variations. A name that differs by only one word or a punctuation mark may still create a conflict.

2. Search the USPTO federal trademark database.
A state-level search only tells you whether the name is taken in your state. It does not tell you whether someone holds a federal trademark on that name or something confusingly similar. The USPTO TESS tool lets you search the full federal trademark register for existing marks that might conflict with your proposed name. This matters because a federal trademark holder can challenge your use of a name even if your state approved it. TESS is free to use and recommended before any registration filing.

3. Check the domain name and social handles.
This step is not a legal requirement, but it is a practical one. If your exact business name is taken as a.com domain or on the platforms where your customers spend time, you will either operate under a fragmented brand or need to rebrand later. Run the search now, before you commit.

A name that clears all three checks is one you can file with confidence. A name that clears only one or two may still create problems. The few minutes this triple-check takes can save weeks of legal back-and-forth after the fact.

Step 2: Choose Your Legal Business Structure

Your legal structure determines where you register, what you file, and how much protection your name gets. Get this decision right before you touch a single form.

The four structures most US founders choose between are:

• Sole proprietorship: No formal state filing required to operate, but you and the business are legally the same person. To use a name other than your own legal name, you will need a DBA filing.
• Partnership: Two or more people operating together. Like a sole proprietorship, it offers no liability separation by default. A DBA or formal partnership registration may be required depending on your state.
• LLC (Limited Liability Company): A state-registered entity that separates your personal assets from business liabilities. The business name is registered as part of the formation filing.
• Corporation: A more formal entity type, typically used when you plan to raise investment or issue stock. The name is also registered through the state formation process.

If you are a sole proprietor operating under your own name, you may not need to register a business name at all. The moment you want to operate under any other name, a DBA filing becomes necessary. If you want liability protection, an LLC or corporation is the structure that provides it, and the name registration happens as part of forming that entity.

The structure you choose now shapes every filing that follows, so it is worth deciding before you move to the next step.

Steps 3 and 4: How Do You Register My Business Name Online With Your State?

Once you know your name is available and your structure is set, you file with the appropriate state agency. The exact agency and process depend on whether you are forming an entity or filing a DBA.

Step 3: Register with your state agency.

For LLCs and corporations, the filing goes to your state's Secretary of State office, or the equivalent agency in states that use a different title. Most states now offer online portals where you can complete the formation filing, pay the fee, and receive confirmation within one to three business days. A handful of states still process paper filings by mail, which can add one to three weeks to the timeline.

Filing fees vary by state. Some states charge relatively low flat fees; others charge significantly more, particularly for corporations. Check your specific state's fee schedule before you start, since costs differ enough to factor into your planning.

Step 4: File a DBA if your operating name differs from your legal entity name.

If you are a sole proprietor, or if your LLC or corporation plans to operate under a name other than its registered legal name, you need a separate DBA filing. In most states, this goes to the county clerk's office rather than the Secretary of State. Some states route it through the Secretary of State directly.

A small number of states require you to publish a notice of your DBA in a local newspaper for a set number of weeks before the registration is complete. This requirement varies by state, and the associated costs depend on local publication rates. Check your state's specific rules before assuming the online filing alone is sufficient.

Name reservations buy you time if you are not ready to file.

Most states let you reserve a business name before you complete the full registration. Reservations typically cost between $10 and $50 and hold the name for 30 to 120 days. This is useful if you need time to finalize your structure or gather formation documents without risking someone else filing the same name first.

Between January and July 2026 alone, the US saw 3,867,036 new business applications, according to MyStateLLC's 2026 research. That volume means popular name combinations disappear fast. If you find a name you want, reserving it while you prepare your full filing is worth the small fee.

Step 5: Do You Need a Registered Agent?

If you are forming an LLC or corporation, yes. Every state requires these entities to designate a registered agent as part of the formation process.

A registered agent is a person or company with a physical address in your state who agrees to receive official legal documents on behalf of your business. This includes service of process (meaning lawsuit paperwork), state correspondence, and compliance notices. The address must be a street address, not a P.O. box, and someone must be available there during normal business hours.

You can serve as your own registered agent if you have a physical address in the state where you are registering and you are consistently available during business hours. Many founders choose this option to save money in the early stages. The risk is that legal documents, including time-sensitive ones, may arrive when you are unavailable, traveling, or simply not watching that address closely.

Using a professional registered agent service costs more, but it keeps your personal address off the public record and ensures nothing gets missed. If you operate in multiple states, a professional service also handles the registered agent requirement in each state from a single account.

Sole proprietors filing only a DBA generally do not need a registered agent, since a DBA does not create a separate legal entity. The requirement applies specifically to LLCs, corporations, and other formal entity types.

Step 6: Apply for an EIN After Your Name Is Registered

An EIN, or Employer Identification Number, is a nine-digit federal tax ID assigned by the IRS. Think of it as a Social Security number for your business. You need one to open a business bank account, hire employees, file business taxes, and, in many cases, sign contracts as an entity rather than as an individual.

Sole proprietors with no employees can sometimes operate under their personal Social Security number, but getting an EIN is still recommended. It keeps your personal tax ID out of vendor agreements and business documents.

The IRS EIN Portal provides a free online application that takes about 10 to 15 minutes to complete. You receive your EIN immediately upon approval. The portal is open Monday through Friday, 7 a.m. to 10 p.m. ET. Sessions time out after 15 minutes of inactivity, so have your formation documents and personal identification ready before you start. Do not close the browser before saving or printing your confirmation, since the IRS does not re-display the EIN after the session ends.

Apply after your entity is formed or your DBA is on file, not before. The IRS application asks for your legal business name and structure, and those need to match your state registration exactly.

DIY vs. Filing Service: Which Option Is Right for You?

Most founders can register their business name without professional help. The question is whether the time and error risk are worth the savings. According to MyStateLLC's 2026 research, 3,867,036 new business applications were filed in the US between January and July 2026 alone. A large share of those founders filed on their own. Some hit problems. Others did not.

Here is how the two paths compare:

Factor	DIY via State Portal	Filing Service
Cost	State filing fee only	Service fee plus state filing fee
Speed	1–3 business days online	Same or slightly faster with expedited options
Error risk	Higher if unfamiliar with forms	Lower, errors caught before submission
Support	None beyond state instructions	Guided process or human review
Name check	You run it manually	Usually included
Best for	Simple structures, confident filers	First-time filers, multi-state needs, time pressure

DIY works well when you are forming a single-member LLC in a state with a clear online portal, you have already run your name availability triple-check, and you have time to read the instructions carefully. The state portal will not catch a name conflict you missed, and it will not flag a form error before you submit.

A filing service adds value when the stakes are higher. California, for example, requires LLCs to file a Statement of Information within 90 days of formation, and missing that deadline triggers a penalty. If you are registering in multiple states, or if your state has layered requirements like that, a service that catches those deadlines before you miss them is worth the extra cost.

LegalMente AI is a legal AI platform that handles business formation alongside contract review, document drafting, and ongoing legal questions, all through a single platform.

FAQs

How much does it cost to register a business name in Florida?

Florida's filing fees vary depending on your business structure. LLC formation and DBA filings each carry separate fees set by the state. Florida's fees vary by entity type; check the Florida Division of Corporations website for current rates before you file.

Do I need to register my business in Alabama?

If you are operating under any name other than your own legal name, or if you are forming an LLC or corporation, yes. Alabama requires formal registration for LLCs and corporations through the Secretary of State's office. Sole proprietors using a trade name need a DBA filing at the county level. Operating without the required registration can expose you to fines and limit your ability to open a business bank account or sign contracts as an entity.

What are the different types of business structures in the US?

The four structures most US founders use are sole proprietorships, partnerships, LLCs, and corporations. A sole proprietorship is the default for a single person operating without a formal entity. A partnership applies when two or more people operate together. An LLC creates a separate legal entity with liability protection. A corporation is a more formal structure typically used for investment or stock issuance. Each structure determines where and how your business name gets registered.

How long does a business name reservation last, and how much does it cost?

Business name reservations typically cost between $10 and $50 and hold your chosen name for 30 to 120 days before formal registration. The exact duration and fee depend on your state. A reservation is useful if you need time to finalize your structure or gather formation documents without risking someone else filing the same name first. It does not replace the full registration, it just holds your spot.

Can someone else take my business name while I am waiting to file?

Yes. Until your registration or reservation is on file with the state, the name is available to anyone else who files first. State databases update in near real time for online filings, so a competitor could claim the same name hours after you confirmed it was available. If you find a name you want but are not ready to complete the full filing, use your state's name reservation option to protect it while you prepare.

Conclusion

Registering your business name is a multi-step process, not a single form. The path depends on whether you need a trade name on record or a full legal entity, and getting that decision right before you file saves you from re-filing later at extra cost. Run the availability triple-check, choose your structure, file with the right state agency, and get your EIN in place once the name is confirmed.

Once your name clears the availability triple-check, the next decision is structure. If you need liability protection, file your LLC formation at the same time you confirm the name, so both are on record together. That single filing step is where most founders either get the foundation right or create problems they fix later at extra cost.
