Louisiana Naming Requirements

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."

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 restrictions for LLC names:

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


It is important that your name be distinguishable from all other business names. In Louisiana, a distinguishable name is one that is substantively different from all other existing or reserved business names in the state.

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