We’re here to help you find the right business name for your Mississippi LLC. From searching for a business name with the Mississippi Secretary of State to understanding naming rules or creating a “Doing Business As” name to register your entity, you’re in the right place.

Mississippi Secretary of State LLC Business Search

You should start naming your business by completing a Mississippi business entity search” with the secretary of state. They have a helpful tool on their website that lets you search the register of Mississippi LLCs and corporations to see if someone already has your desired business name. Just visit the Business Search Tool on the Mississippi SOS website and enter the MS business name you want to search for.

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

The Mississippi Secretary of State search tool lets you enter details and search for your MS LLC by the following fields:

  • Business Name
  • Business ID
  • Officer Name
  • Registered Agent

Mississippi Secretary of State Rules for Naming Your LLC

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

Standard LLC Naming 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 Mississippi 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 Mississippi. This is why you should check business name availability on the MS 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 another corporation or LLC in Mississippi. 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 MS agency or organization (e.g. FBI, FDA, Mississippi Department of Revenue, Mississippi 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

Mississippi LLC Trade Names

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

For example, your LLC might be called Mississippi Leisure and Tourism Holding Company LLC and you have a chain called Steamboat. You should file a Trade Name to let the Mississippi Secretary of State know. In Mississippi, you do that through a form, or you can have Incfile do it on your behalf through our Assumed Business Name service.

Register Your Mississippi LLC Business Entity

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

  • If you don’t want to form your Mississippi LLC right now, you can reserve the business name
  • If you’re ready to start your Mississippi LLC, you can register it through Incfile
