If you want to register a DBA in Louisiana, known as a trade name, that’s a separate process that requires filing a separate form with the Secretary of State.

Reserve Your Name

While not required, you have the option to reserve your corporation name in Louisiana for up to 120 days before you register it. This prevents other businesses from registering your name until you are ready to register it yourself. 

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

Louisiana Corporation Name Requirements

Key Guidelines

Louisiana has official requirements for its corporation names.

The name must include one of the following words or abbreviations (with or without punctuation): corporation, incorporated, company, limited, corp., inc., co., or ltd.

There are also restricted words, such as “FBI” or “Treasury,” that you cannot use in order to keep your LLC from sounding like an official institution.

Louisiana also has the following restrictions for corporation names:

  • The name cannot imply that the corporation is organized for any unlawful purpose or one not outlined in its Articles of Incorporation. It also cannot contain any words “that consist of or comprise immoral, deceptive, or scandalous matter.”
  • The name cannot falsely suggest that your corporation is a charity, nonprofit, or government organization. 
  • The name cannot include the phrase "doing business as" or any abbreviation of that phrase, such as "d/b/a".
  • The name cannot include the words “casualty,” "redevelopment corporation," or "electrical cooperative."

For more information, check out the Louisiana state statute on corporation names.

Distinguishability

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

If your corporation name isn’t distinguishable, your Articles of Incorporation filing will likely be rejected.
