Idaho LLC Name Search — Step 1 of 8
Idaho gives you an unusually wide set of acceptable designators — including one most states don't allow. Here's how to pick a name that clears the Secretary of State's review the first time.
Your Idaho LLC name must include "Limited Liability Company," "Limited Company," or the abbreviation "L.L.C.," "L.C.," or "LLC" — Idaho is one of the few states that accepts "L.C." as a standalone abbreviation. Search for free using the Idaho Secretary of State's business entity search before filing. There's no separate name reservation fee bundled into a normal filing — your name is approved automatically when your Certificate of Organization is accepted. Note: a dissolved business's name stays protected for up to 6 months, so a name that looks free may not actually be available yet.

Idaho Naming Rules
Under Idaho Code §30-21-301, every Idaho LLC name must follow a few clear rules:
- Include a designator — "Limited Liability Company," "Limited Company," or the abbreviation "L.L.C.," "L.C.," or "LLC" must appear in the name.
- "L.C." is unusually accepted here — most states only allow "LLC" or "L.L.C.," but Idaho also permits the shorter "L.C." or "LC" abbreviation.
- Be distinguishable — your name can't be identical, or confusingly similar, to any other business name already on file with the Secretary of State.
- Avoid restricted words — terms implying a bank, insurance company, university, or federal agency generally require additional approval or licensing before you can use them.
- Search first — use the Idaho Secretary of State's free business entity search to confirm availability before you file.

Type your proposed name to check it against Idaho's core naming rules:
Reserving Your Name (Optional)
- Not required, but available — if you're not ready to file your Certificate of Organization yet, you can reserve your chosen name to lock it in temporarily.
- Most people skip this step — since your name is approved automatically the moment your Certificate of Organization is accepted, reservation is really only useful if there's a meaningful delay before you're ready to file.
- Trade name (Assumed Business Name) — if you want to operate under a different public-facing name than your LLC's legal name, file a Certificate of Assumed Business Name with the Secretary of State.
- Idaho DBAs don't expire — unlike most states, an Idaho assumed business name registration is filed once and never needs periodic renewal.
A dissolved business's name isn't immediately freeIf you find a name that appears to belong to a dissolved business, don't assume it's instantly available. Idaho protects a dissolved entity's name for up to 6 months after dissolution, so it may still be reserved even though the business search shows it as inactive.
