Search for the Perfect LLC Name and Register It with the Indiana Secretary of State

Your Indiana business entity needs the perfect name, and we’re here to help. In this section we’ll guide you through searching the IN Secretary of State business registry, tell you about the rules for naming your business, describe assumed names and get you started with registering your LLC.

Indiana Secretary of State Business Search

You should start naming your business by completing an “Indiana business entity search” with the secretary of state. They have a helpful tool on their website that lets you search the register of IN LLCs and corporations to see if someone already has your desired business name.

If the business name is already used, that means it’s not available and you won’t be able to register it. Try running an LLC search for a different business name instead.

Rules on Indiana LLC Name Availability

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Indiana Secretary of State (SOS) naming rules. These do vary from state to state — we’ve got general naming rules below, as well as naming rules specific to LLC businesses formed in IN.

Your LLC Business Name Must Be Unique

The business name you have chosen cannot be used by any other LLC or corporation in the state of Indiana. This is why you should check business name availability on the IN SOS website.

Your LLC Business Name Must Not Be Confusable with Another Business Name

It’s not enough for your IN LLC name to be unique. It also cannot be similar to the name of a corporation or LLC in Indiana. For example, you cannot use the following factors to say your name is different from the name of another business:

  • Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., Ltd., LLC, etc.
  • Definite articles like “A,” “And,” “An,” “&,” “The,” etc.
  • The singular, plural or possessive forms of a word
  • Abbreviations, punctuation, symbols, fonts, typefaces, etc.
Your LLC Business Name Must Contain Certain Words

All LLCs must have the words “Limited Liability Company,” “L.L.C.” or “LLC” in their name. These words should normally come at the end of the name.

Your LLC Business Name May Have Other General Restrictions

Most states will not allow you to form LLCs with names that:

  • Are very similar to the name of a federal or IN agency or organization (e.g., FBI, FDA, Indiana Department of Revenue, Indiana Police, Treasury, etc.)
  • Suggest affiliation with a federal or state agency or organization
  • Use the term “Olympic” or any terms that are trademarks of the Olympic organization
  • Imply a purpose that it would be illegal for your business to carry out

Assumed Business Names in Indiana

You might choose to do business under a different name from your legal LLC name. In Indiana, doing business under a different name is known as an “Assumed Name.” You might choose to use a different name from your formal IN LLC name for a variety of reasons.

For example, your LLC might be called Indiana Architecture and Engineering Holding Company LLC, but you provide your main service as Indianapolis Commercial Building Services. You should file an assumed name to let the Indiana Secretary of State know. In Indiana, you do that through a Certificate of Assumed Business Name form, or you can have Incfile do it on your behalf through our Assumed Business Name service.

Register Your Business Name with the Indiana Secretary of State

Once you’ve searched for your Indiana business name, checked availability, followed the naming rules and decided whether you need an assumed name, you can register your IN LLC name. There are a couple of ways to do this:


If you don’t want to form your Indiana LLC right now, you can reserve the business name with the Indiana Secretary of State. You will need to complete a Reservation of Business Name and file it with the IN SOS. You do not need to reserve a name if you are forming your business right away.
