Search for and Register Your Idaho LLC Name

Whether you’re searching for the right Idaho business name or registering your LLC with the ID Secretary of State, we can help. We’ve got all the information you need on a Idaho business entity search, LLC naming rules, fictitious names and registering your business.

Idaho Business Entity Search

You need to check whether there’s already another Idaho LLC registered with your desired business name. That means searching the Idaho Secretary of State website using their business search tool. You can easily look up LLCs and corporations by name and other details.

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

Idaho SOS Naming Rules for LLCs

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Idaho Secretary of State naming rules.

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 Idaho. This is why you should check business name availability on the ID SOS website.

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

It’s not enough for your LLC name to be unique. It also cannot be similar to the name of a corporation or LLC in Idaho. 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 ID agency or organization (e.g., FBI, FDA, Idaho Department of Revenue Administration, Idaho 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 would be illegal for your business to carry out

Idaho Assumed and “Doing Business As” (DBA) Names

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

For example, your LLC might be called Idaho Potato Processing Holding Company LLC and you have a brand called Northwestern Kettle Chips. You should file an assumed business name to let the Idaho Secretary of State know. In Idaho, you do that through the Cancellation or Amendment of Certificate of Assumed Business Name form, or you can have Incfile do it on your behalf through our Assumed Business Name service.

Business Name Registration for Your Idaho LLC

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

  • If you don’t want to form your LLC right now, you can reserve the business name with the Idaho Secretary of State. You will need to complete an Application for Reservation of Name and file it with the ID SOS. 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 Idaho LLC name does not infringe on the trademark or service mark of another business.
