How to Name Your LLC: Rules, Tips, and Mistakes (2026)

Learn how to name your LLC in 2026. We cover the designator rule, distinguishability, availability search, name reservation, DBAs, and trademark checks.

To name your LLC, you pick a unique business name, add a required designator like LLC or Limited Liability Company, and confirm it's available through your state's Secretary of State. The name must be distinguishable from every other registered business in your state. This guide walks through the rules, the search, and the extras like reservations and DBAs.

Every LLC name needs a designator

State law requires your legal name to include a designator that tells the public you run a limited liability company. The most common options are LLC, L.L.C., or the full phrase Limited Liability Company. Some states also accept variations like LC or Limited Company.

You can't use a designator that suggests another business type. For example, you generally can't end your name with Inc., Corp., or Co. unless you actually formed a corporation. The designator is a legal requirement, not a style choice.

The distinguishability rule

Your name must be distinguishable from every other business name already on file in your state. That means it can't be the same as an existing name, and it can't be so similar that a reasonable person would confuse the two.

Minor differences usually don't count. Changing LLC to Limited Liability Company, adding a comma, or swapping in a different designator won't make a name distinguishable. A different word, a different spelling, or a clearly different order of words usually will.

Run a name search first

Before you file, check availability through your state's Secretary of State business name database. Most states offer a free online search tool. You can also use a dedicated LLC name search to check availability across multiple states at once.

• Search your state's Secretary of State database first.
• Check federal trademarks through the USPTO.
• See if the matching domain name is available.

Keep in mind that a state search only tells you about names registered in that state. It won't tell you about trademarks, domain names, or businesses in other states. A name can be available in your state and still conflict with a federal trademark.

Reserve a name before you file

If you've settled on a name but aren't ready to file your formation documents, you can reserve it. A name reservation holds the name for a set period, usually 60 to 120 days, so no one else can take it while you prepare.

Reservation fees are small, typically $10 to $50 depending on the state. You can usually renew a reservation if you need more time. Once you file your articles of organization, the name is officially yours.

Use a DBA for a brand name

Your legal LLC name doesn't have to be the name you do business under. If you want to operate under a different brand name, you can file a DBA, short for doing business as. This lets you use a trade name while keeping your legal name on file.

• File a DBA with your state or county.
• Renew it on schedule, usually every few years.
• Keep your legal LLC name on file.

A DBA is useful if your legal name is long, or if you want to run multiple brands under one LLC. It doesn't create a separate legal entity, and it doesn't give you any extra liability protection. Learn more about the difference in our guide to LLC vs DBA.

Check trademarks before you commit

State registration doesn't protect your name nationwide. A trademark does. Before you invest in branding, search the U.S. Patent and Trademark Office database to make sure your name isn't already trademarked in your industry.

You don't need a trademark to form an LLC, but it's smart to check early. A conflict can force you to rebrand later, which is expensive. If your name is clear, you can apply for a federal trademark to protect it across the country.

Frequently Asked Questions

What are the rules for naming an LLC?

Your LLC name must include a designator like LLC or Limited Liability Company, must be distinguishable from other names on file in your state, and can't suggest a different business type. You also can't use restricted words like bank or insurance unless you hold the proper license.

How do I check if an LLC name is available?

Search your state's Secretary of State business name database, which is usually free and online. The search tells you if the name is already taken or too similar to an existing one. It won't check trademarks or domain names, so do those separately.

Can I use a different name than my LLC name?

Yes. You can file a DBA, or doing business as, to operate under a brand name that differs from your legal LLC name. The DBA doesn't create a new entity and doesn't add liability protection, but it lets you market under a name you prefer.

How much does it cost to reserve an LLC name?

Name reservation fees are typically $10 to $50, depending on your state. A reservation holds the name for a set period, usually 60 to 120 days, so no one else can claim it while you prepare your formation documents. You can usually renew it if you need more time.

Do I need a trademark for my LLC name?

No, a trademark isn't required to form an LLC. But it's wise to search the USPTO database before you commit to a name. A federal trademark protects your name nationwide and can prevent a costly rebrand if a conflict shows up later.
