Hawaii's Naming Rules
Hawaii's LLC naming requirements come from HRS §428-105 and are fairly standard for the mainland-style LLC model:
- Must include a designator — "Limited Liability Company," "LLC," or "L.L.C."
- Must be distinguishable from every other business entity on file with the DCCA Business Registration Division.
- Restricted words like "Bank," "Insurance," "University," or "Trust" may require extra approval before use.
- Can't imply a purpose your LLC isn't authorized for, or affiliation with a government agency.

Trade Names and DBAs
Hawaii offers an optional name reservation for $10, lasting 120 days. A database search does not reserve a name or guarantee filing approval. If you are ready to form, you can file the Articles of Organization without buying a separate reservation. A reservation differs from a trade name or trademark. If you will use another business name, review these separate options:
- File an Application for Registration of Trade Name (Form T-1) with DCCA for $51, valid for a 5-year term, renewable for another $50–$51.
- Optional for LLCs — most only need it if operating under a name different from the legal LLC name on file.
- Also check the USPTO trademark database separately — state name availability and federal trademark protection are two different systems.
