Idaho LLC lookup: how to use the SOSBiz Business Search
An LLC lookup in Idaho is the same search as a business search. The SOSBiz Business Search, kept by the Idaho Secretary of State, lists LLCs alongside corporations and other registered businesses. You can search by name or file number. It's free, and you don't need an account.

- Open the SOSBiz Business Search. You don't need an account.
- Type the start of the business name, or the file number, in the box marked "Search by name or file number". The search starts with your keyword.
- Use "Advanced Search Options" to narrow the results.
- Click a row to expand it. You'll see the status, addresses, initial filing date, AR Due Date and registered agent.
- To file an annual report or a change, log in to SOSBiz and open your business record.
Good to know in Idaho: The annual report is free but has a hard deadline: it must reach the Secretary of State by close of business on the last day of your formation month, every year. The record shows the next "AR Due Date", and a company that misses it can be administratively dissolved after a 60-day notice. Assumed business names are filed with the state too, and they no longer expire.
What the search shows you
- Business name with the file number in parentheses, and filing type
- Status
- Filing date
- Registered agent
- Formed in and term of duration
- Principal and mailing addresses
- AR Due Date (next annual report due date)
- Registered agent address, marked commercial or noncommercial
What the status words mean
Idaho uses its own words for a company's status, and they don't always mean the same thing as in other states. Here's what you'll see on the SOSBiz Business Search, in the state's own wording.
| Status | What it means |
|---|---|
| Active-Existing | An active entity on record. SOSBiz shows this on active domestic LLCs. The Secretary of State's help pages don't define it. |
| Active-Good Standing | An active entity. The help pages don't explain how it differs from Active-Existing, so check the AR Due Date on the record. |
| Inactive-Dissolved (Administrative) | The Secretary of State administratively dissolved the entity, for example for not filing its annual report or not having a registered agent for 60 consecutive days. It may only wind up its affairs. An Idaho entity can apply for reinstatement within 10 years ($30). |
| Inactive-Dissolved | Not defined in the help pages. An Idaho LLC closes voluntarily by filing a Statement of Dissolution, which has no filing fee. |
| Inactive-Merged Out | Shown when the entity merged into another entity. The help pages don't define it further. |
For how these compare across states, see what business entity status means.
Finding the registered agent, filing history and owners
Registered Agent
In the expanded record, with the agent's address and whether it's a commercial or noncommercial agent. The agent needs a physical street address in Idaho, not a PO box.
Filing history
Copies of filed records cost 25 cents per page, plus $10 for certification, under Idaho Code 30-21-214.
Owners, managers and officers
Each annual report must name at least one governor. The Secretary of State doesn't keep records of stock ownership. If the state record doesn't name anyone, our guide on how to find the owner of an LLC covers where else to look.
Finding an Idaho File number
Idaho gives every business on its register a File number. It's the quickest way to pin down the right company when names are alike.
- What it looks like
- A number shown in parentheses after the business name in search results (for example 408878).
- Where to find yours
- In the SOSBiz search results, next to the business name.
- Search by it
- Yes. The SOSBiz Business Search accepts it.
It's easy to mix it up with these, which come from other offices:
- Idaho tax permits (seller's permit, withholding account) (Idaho State Tax Commission). Issued through the Idaho Business Registration (IBR) process after you register with the Secretary of State. They're tax permits, not the SOS file number.
Your federal EIN is a different number again. See which business number a form is asking for.
Checking whether a business name is available in Idaho
- Search the name in the SOSBiz Business Search.
- Reserve a name for 4 months with an Application for Reservation of Legal Entity Name ($20 online, $40 on paper).
- An assumed business name that isn't distinguishable from a registered name needs a written consent letter from that name's owner.
A clear result on the state search isn't a trademark clearance. If the name matters to you, also search the USPTO trademark database and check the domain. More in our business name search guide.
