How to search Missouri business entities online

Missouri business entity records are searchable at bsd.sos.mo.gov/BusinessEntity/BESearch.aspx, operated by the Missouri Secretary of State's Corporations Unit. The portal requires JavaScript and handles both business entity registration and UCC filing — a tab at the top of the page toggles between the two sections.

What the search covers

The database covers domestic and foreign for-profit corporations, close corporations, professional corporations, agricultural cooperatives, mutual associations, LLCs, limited partnerships, LLPs, nonprofit corporations, and fictitious names. The portal is the single system for all of these record types.

Search modes

Missouri offers more name search granularity than most states:

• Includes Names — finds the term anywhere in the name
• Starting With — starts-with match
• All Words — every word you enter must appear in the name
• Any Word — at least one of your words appears in the name
• Exact Match — requires the full legal name including corporate designator (Inc., LLC, etc.) and punctuation

Additional search fields include Registered Agent name and Charter Number (the Missouri entity ID). Results default to active entities only; unchecking "Only Active Corporations" adds dissolved and revoked records.

Entity detail

Each record has two tabs: General Information and Filings. The General Information tab shows the charter number, status, formation date, registered agent name and address, and officer/director information. The Filings tab lists every document on file with the Secretary of State, with links to document images. Certificates of Good Standing and certified copies can be ordered directly from the record.

Annual reports — a note on due dates

Missouri LLCs do not file on a calendar-year basis. The annual registration report is due at the end of the entity's anniversary month — the month in which the LLC was formed or qualified to do business. For corporations, the annual registration report is also tied to the anniversary month. Confirm the exact due date for your entity by reviewing the record detail page.
