Idaho business entity information, including entity name, type, file number, and formation date, is available through the Idaho Secretary of State's SOSBiz business search portal. This guide walks you through how to search the database, where to find each piece of information, and what format each data point takes in Idaho's system.

Summary table: finding your Idaho entity information

How to search for Idaho business entities

The SOSBiz portal is the Idaho Secretary of State's official business search system. Navigate to the Idaho SOSBiz portal and use the Business Search interface, which offers separate modes for searching by name, by file number, by city, and by date of organization or authorization. The SOSBiz Help page provides guidance on each method.

While Idaho's system supports partial matches, using your complete legal name as registered produces the most precise results. Advanced search lets you filter to active entities only, combine multiple criteria, filter by registered agent, and use name-matching modes such as "Begins with," "Contains," or "Exact match."

Click the entity name in the results to view complete details. A panel appears on the right side of the screen showing the legal entity name, entity type, file number, formation or registration date, current status, Idaho registered agent information, principal office address, and complete filing history with downloadable documents. No login is required to search; all business entity information filed with the office is public record.

How to find your entity number in Idaho

Your Idaho entity number was assigned by the Idaho Secretary of State when your entity was formed and serves as your unique business identifier across all filings. Idaho generally refers to this identifier as a "File Number" on official SOS forms and in the SOSBiz portal. Some interfaces may also use "Organizational ID" or "Filing Number" for the same identifier.

Where to locate your Idaho file number

1. Idaho business search (fastest method)

• Displayed on the entity details page, labeled "File Number"

2. Certificate of Organization/Incorporation

• Usually at the top of the document, stamped with the Idaho Secretary of State seal

3. Annual reports and correspondence

• Appears on all official Idaho Secretary of State documents and is used as your account identifier for ongoing filings

How to find your entity type in Idaho

Idaho recognizes a range of business entity types, listed as shown in your search results and formation documents. The SOS Business Forms page provides the current list of recognized categories.

Where to find your Idaho entity type

1. Idaho business search (most accessible)

• Displayed prominently in search results and the entity profile, labeled "Entity Type." Idaho recognizes (but is not limited to) LLCs, corporations (for-profit, nonprofit, professional, and benefit), partnerships, limited partnerships, and limited liability partnerships. For the full current list, refer to the Idaho SOS Business Forms page.

2. Certificate of Organization/Incorporation

• States the specific entity type formed; uses Idaho's official terminology (for LLCs, the document is titled "Certificate of Organization," not "Certificate of Formation")

3. Annual reports

• Listed in the entity information section and cannot be changed without a formal amendment filing

For PLLCs and other professional entities, check the entity type field on your specific SOSBiz record to confirm categorization.

How to find your formation date in Idaho

Your formation date appears in Idaho business search results and is part of the state's official records, though it may not always be prominently printed on your Certificate of Organization or Articles of Incorporation.

Where your Idaho formation date appears

1. Idaho business search (easiest access)

• Displayed in search results and the entity profile, labeled "Initial Filing Date" or "Date of Organization/Authorization" depending on entity type. Standard MM/DD/YYYY format.

2. Certificate of Organization/Incorporation

• At the top of the document, often stamped with the Idaho Secretary of State seal and official filing date

3. Annual report confirmations

• References the original filing date and appears in the filing history timeline

Formation date vs. effective date in Idaho

Idaho Code § 30-21-203 governs effective dates and times for Title 30 entity filings. Most filings become effective when filed and approved, though certain filing types permit a delayed effective date of up to 90 days from the filing date.

For nonprofit corporations, Idaho Code § 30-30-203 provides that corporate existence begins upon filing unless a delayed effective date is specified. Statements of correction may not specify a delayed effective date per Idaho Code § 30-21-205.

The date shown in SOSBiz typically represents when the Idaho Secretary of State processed your formation documents, making this your official formation date for most purposes. Processing times vary; check the Idaho SOS business resources page for current estimates.
