Before you form, buy from, or partner with an Idaho company, you need two answers: is the business name free, and is the entity real and current? The Idaho business entity search settles both in minutes.
Run it free on the Idaho Secretary of State (SOS) SOSBiz portal. Use the official Idaho Secretary of State business search. No account or login is required to search. This guide covers the search, the record fields, and every status label.
What Is the Idaho Business Entity Search?
The Idaho business entity search is the Secretary of State’s free public lookup on the SOSBiz portal. It covers every entity registered in Idaho: limited liability companies (LLCs), corporations, limited partnerships (LPs), limited liability partnerships (LLPs), assumed business names, and out-of-state (foreign) companies authorized in the state. Searching needs no account; only filing does, per the Idaho Secretary of State.
The portal is a single hub. The same site also holds the state’s lien and trademark searches, covered below.
How Do You Search for a Business in Idaho? (Step by Step)
Go to the SOSBiz business search, type a business name or file number, and open a result to read the full record. One search box handles both inputs. An advanced caret adds match modes and filters. Searching is free and needs no login, per the Idaho Secretary of State.
- Open the SOSBiz business search.
- Enter a business name or file (entity) number in the single search box.
- Click the advanced caret to choose “Starts with” or “Contains,” check “Search by Registered Agent,” limit to “Active entities only,” or set a filing-date range.
- Widen results with partial names; drop suffixes such as LLC or Inc. and strip punctuation.
- Select a result to open its record.
What Does an Idaho Entity Record Show?
An Idaho entity record shows the filing type, status, formation date, term, principal and mailing address, initial filing date, annual report due date, and registered agent with an Idaho street address. Filed documents download free. Certified copies and certificates cost $10 through the record’s “Request Certificate” button, per the Idaho Secretary of State Certificate Request form.
Owners and members are usually not listed. The public state filing shows the entity and its registered agent, not internal ownership records.
What Do Idaho Business Status Labels Mean?
Idaho shows “Active-Existing” for an entity that exists and is current. Any other label means the business closed voluntarily, was terminated by the state, or lost its foreign authority. “Good Standing” never appears in the results grid; you prove it with a $10 Certificate of Good Standing, per the Idaho Secretary of State Certificate Request form.
| Status label | What it means | What it means for you | Source |
|---|---|---|---|
| Active-Existing | Registered and current on filings | Safe to transact; the name is taken | Idaho SOSBiz search results |
| Dissolved | Closed voluntarily by the owners | Wound down; confirm before relying on it | Idaho SOSBiz search results |
| Administratively Dissolved | Terminated by the state, usually for a missed annual report | Red flag; the name may free up | Idaho Code § 30-21-602 |
| Revoked | A foreign entity’s authority to operate in Idaho ended | Not authorized to do business in Idaho | Idaho SOSBiz search results |
What Happens If an Idaho Business Is Administratively Dissolved?
It missed its annual report. Idaho administratively dissolves an entity that does not cure within 60 days after the Secretary of State serves notice, per Idaho Code § 30-21-602. The report is due by the last day of the anniversary month and costs $0 online. A dissolved entity can reinstate within 10 years for $30, per Idaho Code § 30-21-603.
For due diligence, an Administratively Dissolved counterparty is a warning sign. It also means a “taken” name held by that entity may become available.
| Item | Rule or fee | Source |
|---|---|---|
| Annual report due | Last day of the anniversary month | Idaho Secretary of State |
| Annual report fee, online | $0 | Idaho Secretary of State |
| Annual report fee, paper (in person, Boise) | $20 | Idaho Secretary of State |
| Cure window after SOS notice | 60 days | Idaho Code § 30-21-602 |
| Reinstatement fee | $30 | Idaho Code § 30-21-603 |
| Reinstatement deadline | 10 years after dissolution | Idaho Code § 30-21-603 |
Which Business Types Appear in an Idaho Entity Search?
Every entity registered with the Secretary of State appears. Sole proprietorships without an assumed business name (ABN) do not, which is the top reason a real business returns no results. The table maps each Idaho entity type to its formation document and state filing fee.
| Entity type | Idaho formation document | State filing fee (online / paper) | Source |
|---|---|---|---|
| LLC / professional LLC (PLLC) | Certificate of Organization | $100 / $120 | Idaho SOS Certificate of Organization form |
| Corporation (for-profit, nonprofit, professional) | Articles of Incorporation | $100 / $120 | Idaho Secretary of State |
| Limited partnership (LP) | Certificate of Limited Partnership | Varies | Idaho Secretary of State |
| Limited liability partnership (LLP) | Statement of Qualification | Varies | Idaho Secretary of State |
| Assumed business name (ABN / DBA) | Certificate of Assumed Business Name | $25 / $45 | Idaho SOS Certificate of Assumed Business Name form |
| Foreign entity | Foreign Registration Statement | Varies | Idaho Secretary of State |
How Do You Check if a Business Name Is Available in Idaho?
Search with “Contains” and no suffix. Zero conflicting results means the name is likely open, but Idaho requires names to be distinguishable on the record, and the Secretary of State makes the final call at filing. Reserve a clear name for four months for $20 online ($40 by mail), per the Idaho SOS Application for Reservation of Legal Entity Name.
Entity clearance is not trademark clearance. Run the SOSBiz trademark search too, and use a company name checker to scan availability before you commit.
How Do You Search for a DBA or Assumed Business Name in Idaho?
Assumed business names (ABNs), also called DBAs (doing business as), are filed with the Secretary of State for $25 and appear in the same SOSBiz business search. Search the trade name, then open the record to find the legal owner. This is why a storefront name and the legal entity name often differ.
Anyone clearing a new name should search both registered entities and assumed business names, since an ABN can conflict with a proposed name.
Can You Search UCC Filings and Trademarks in Idaho?
Yes. Both live on SOSBiz. The Uniform Commercial Code (UCC) lien search reveals liens on a business’s assets, a core step for lenders and buyers. The state trademark search covers Idaho trademark and service mark registrations, which are separate from entity names.
Run the UCC lien search before lending to or buying a business. Run the state trademark search to confirm a mark is clear at the state level; federal marks are a separate USPTO check.
Why Does Your Idaho Business Search Return No Results?
Usually the query, not the database. Switch to “Contains,” strip punctuation and suffixes, and try the file number or the registered agent. Other causes: the business trades under a DBA, it is an unregistered sole proprietorship, or the filing is too recent to index.
Dissolved entities still appear, because the search is historical, not current-only. If a name matches a company in another state, remember this database is Idaho-only.
How Commenda Helps After Your Idaho Business Search
An Idaho business entity search confirms a name is free and an entity is real. Keeping your own entity “Active-Existing” is the ongoing work. Commenda’s entity management platform handles that: a compliance calendar for every annual report deadline, registered agent tracking, and filings done for you.
Forming the entity first? Commenda incorporation files your Certificate of Organization or Articles of Incorporation with the Secretary of State. See what an Idaho LLC costs before you file, and map every state deadline with the compliance calendar.
