MI Business Entity Searches & Naming Your Michigan LLC

Whether you’re searching for the right name for your new business or want to register your company name with the MI Department of Licensing and Regulatory Affairs, we can help. We’ve got all the information you need on Michigan LLC searches, LLC naming rules, fictitious names and registering your business.

Michigan Secretary of State Business Search

While most people think of the secretary of state when it comes to naming and registering a new business, in Michigan you actually want the Department of Licensing and Regulatory Affairs (LARA). You should start naming your business by completing a Michigan business name search. We have a simple business name search tool that searches the business registry of LARA.

We’ll complete a search on your behalf and let you know if another LLC or corporation is already using your desired business name.

If the business name is already used, that means it’s not available, and you won’t be able to start a business with that name. Try searching for a different business name in the corporation search tool instead.

The department also has a helpful tool on their website that lets you search the register.

Rules on Michigan LLC Name Availability

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Michigan Department of Licensing and Regulatory Affairs naming rules. These do vary from state to state — we’ve got both general naming rules below as well as naming rules specific to MI.

General Business Name Availability Rules

These rules typically apply to all LLCs, no matter what state they are formed in. You will need to pay attention to these rules, as they will influence the name you choose for your Michigan LLC.

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 Michigan. This is why you should check business name availability on the MI LARA website.

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

It’s not enough for your MI LLC name to be unique. It also cannot be similar to the name of another corporation or LLC in Michigan. 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 MI agency or organization (e.g., FBI, FDA, Michigan Department of Treasury, Michigan 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

Specific LLC Naming Rules for Michigan

In addition to the general rules listed above, the Michigan Department of Licensing and Regulatory Affairs has some specific business naming rules for your LLC. You will need to follow these rules if you want to name your MI business appropriately.

A Limited Liability Company name may not include the words "Corporation", "Incorporated" or the abbreviations "Corp." or "Inc."

Michigan LLC Fictitious Names

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

For example, your LLC might be called Michigan Tourism Holding Company LLC, and you have a chain called Great Lakes Apparel. You should file a Certificate of Assumed Name to let the Michigan Department of Licensing and Regulatory Affairs know, or you can have Incfile do it on your behalf through our Assumed Business Name service.

Register Your Business Name in Michigan

Once you’ve searched for your Michigan business name and checked availability with our business name search tool, it’s time for some next steps. You will need to check the naming rules and decide if you want a fictitious name. Once that’s done, you can register your MI LLC name. There are a couple of ways to do this.


If you don’t want to form your Michigan LLC right now, you can reserve the business name with the Michigan Department of Licensing and Regulatory Affairs. You will need to complete an Application for Reservation of Name and file it with the MI LARA. You do not need to reserve a name if you are forming your business right away.

Trademarks and Service Marks

You must be careful that your Michigan LLC name does not infringe on the trademark or service mark of another business.
