Quick answer: Idaho Business Entity Search
What the Idaho Business Entity Search does
The Idaho Business Entity Search is a free public lookup of every entity registered with the Idaho Secretary of State, run through the SOSBiz portal. It confirms an entity’s name, file number, status, registered agent, and annual report due date. It is the first check founders, investors, suppliers, and banks make before doing business with a company.
How to run an Idaho business search
Follow these steps on the official Idaho SOSBiz portal. Searching is free and needs no account or login.
Open the SOSBiz search
Go to sosbiz.idaho.gov, the official Idaho Secretary of State business search page.
Enter a name or file number
One search box handles both. Type a full or partial business name, or the file (entity) number.
Open the advanced options
Click the advanced caret to choose Starts with or Contains, search by registered agent, limit to active only, or set a filing-date range.
Open the entity record
Click a result to view filing type, status, formation date, addresses, annual report due date, and registered agent.
Check the status label
Look for Active-Existing, the combined label meaning the entity legally exists and is current on its filings.
What each result field means
Once you open an entity’s record, read the status field first. Idaho uses a single combined label, Active-Existing, which means the entity legally exists and is current on its filings. Because the annual report is free, an inactive Idaho entity usually reflects an abandoned business rather than a missed payment. The record also shows the annual report due date.
| Field | What it tells you |
|---|---|
| Entity Name | The legal registered name of the business |
| File Number | The unique file number assigned by the Secretary of State |
| Filing Type | LLC, corporation, nonprofit, or partnership |
| Status | Active-Existing, or dissolved |
| Registered Agent | The agent with an Idaho street address |
| Addresses | Principal and mailing address on file |
| Annual Report Due | The date the free annual report is due each year |
Search using Contains with no entity suffix like LLC or Inc. to catch close matches. If no conflicting names appear, the name is likely open, but Idaho requires names to be legally distinguishable on the record. The Secretary of State makes the final call when you file. You can reserve a name for four months for a $20 base filing fee.
What you can and can’t find in Idaho records
Idaho records are public and searchable on SOSBiz. The registered agent, principal and mailing addresses, file number, status, and annual report due date are all visible. Some internal details stay off the record. Here is what is visible and what is not.
🔓 Public on the record
- Company legal name
- File number
- Registered agent & address
- Entity type & status
- Annual report due date
🔒 Never disclosed
- Operating Agreement
- Ownership percentages
- Internal financials
- EIN & tax filings

Founders who want to keep their own name and home address off the public record often use a registered agent service instead. Be Filing provides a registered agent in Idaho so your personal details stay off the public filing.
