How to Search Available LLC Names in Louisiana

1. Check Louisiana LLC Naming Guidelines

Before you do a name availability search, it makes sense to check if your business name meets the basic state guidelines.

Some key guidelines for Louisiana LLC names include:

  • Your name must include the phrase “limited liability company” or the abbreviations LLC or LC.

  • Your name must be distinguishable from any existing business in the state. This includes Louisiana reserved names.

  • Names of low-profit limited liability companies must have the words "low-profit limited liability company," the abbreviation "L3C," or the abbreviation "l3c."

  • Your name cannot imply that the LLC is organized for any unlawful purpose or one not outlined in its articles of organization.

Keep an eye out for restricted words. These words, such as “FBI” or “Treasury,” are often restricted to keep your LLC from sounding like an official institution.

Louisiana also has the following LLC name restrictions:

  • You must have approval to include certain words:

    • You must have approval from the Louisiana Professional Engineering and Land Surveying Board to include the words "engineer," "engineering," "surveyor," "surveying," (or any variations).

    • You must have approval from the Louisiana Commissioner of the Office of Financial Institutions to include any of the following words: bank, banker, banking, savings, safe deposit, trust, trustee, building and loan, homestead, or credit union.

    • Your name cannot include the word “insurance” unless the LLC is an independent insurance agency or brokerage firm.

  • Your name cannot contain the phrase "doing business as" or the abbreviation "d/b/a".

For more information, check out Louisiana’s official state statutes.

2. Complete an LLC Business Name Search

Once you know your LLC name meets Louisiana guidelines, it’s time to make sure it’s available by using the Louisiana Business Filings Search tool.

It is important that your name be distinguishable from all other business names. In Louisiana, a distinguishable name is one that is substantially different from the name of another corporate, LLC, or trade name that is registered or reserved.

Failure to use a distinguishable name could result in your formation filing being rejected.

How to Reserve or Register Your Business Name

Reserve Your Name

You can optionally reserve your LLC name in Louisiana for up to 120 days before you officially register it. This prevents other businesses from registering your name until you have the opportunity to register it yourself.

Name reservations can be filed online or by mail with the Louisiana Secretary of State. The filing fee is $25.

Register Your Name

If you want to register a legal entity name for your LLC, you can do so at the time of formation filing. Louisiana provides a section for your desired LLC name on the Articles of Organization.

Registering a DBA (doing business as) name, called a trade name in Louisiana, is a separate process that requires filing with the Secretary of State.
