How to search Idaho business entities online

Idaho's business entity search is at sosbiz.idaho.gov/search/business, part of the SOSBiz portal operated by the Idaho Secretary of State. The older URL path at sos.idaho.gov/business-services-2/ no longer resolves — the current system is at sosbiz.idaho.gov. All public record information is viewable without an account; a free SOSBiz account is required only to file documents.

What the search covers

The database covers all Idaho business entities: domestic and foreign corporations (profit and nonprofit), LLCs, limited partnerships, limited liability partnerships, general partnerships, assumed business names (ABNs), and statutory trusts. Trademarks and UCC/lien records appear in separate search tabs within the same portal.

How to search

The default search uses a "starts with" name match — type the first few words of the business name. A file number entered in the search field returns a single, precise record. An Advanced search mode allows filtering by entity type, status, and other criteria. Selecting an entity from results opens a panel displaying governors (officers, directors, members, or managers depending on entity type), registered agent name and address, mailing address, and a complete filing history.

Certificate of Existence — a scam warning

The Idaho Secretary of State has posted a formal public warning about deceptive third-party mailers — specifically solicitations from an entity calling itself "ID Certificate Service" that charge businesses for Certificates of Existence they do not need. Idaho businesses are not required to obtain or display a Certificate of Existence. If you do need one for a legitimate purpose (a bank, lender, or contracting partner may ask), request it through the official SOSBiz portal or call (208) 334-2301. Do not pay a third party for this document.

Processing times

Standard filings currently process in approximately 15–20 business days. Expedited service is available for some filing types and is processed within 8 working hours. Same-day service is available if the filing arrives by 1:00 p.m. Mountain Standard Time. Online filings through SOSBiz tend to post faster than paper submissions.
