How to search for Missouri business entities

Access the Missouri business entity search to look up any registered business by name, charter number, or registered agent. Missouri's enhanced search portal offers multiple search methods to help you locate entities quickly and accurately.

For business name searches, enter your search term and select a match type (Starting With, All Words, Any Word, or Exact Match). While Missouri's system supports partial matches, using your complete legal name as registered ensures you get precise results. You can filter results to show only active entities by selecting "Only Active Corporations" if desired.

Click on the business name or charter number in your search results to access the detailed entity profile. This comprehensive view is organized into multiple tabs: General Information, Filings, Principal Office Address, and Contacts, providing complete transparency into the entity's registration and filing history.

What you'll see in search results

• Legal entity name (exact spelling and punctuation)

• Charter Number (Missouri's unique identifier format)

• Entity type (LLC, Corporation, LP, LLP, Not-for-profit Corporation, etc.)

• Status (Active, Forfeited, Expired, Merged, etc.)

• Created Date (formation date)

How to find your formation date in Missouri

Where your Missouri formation date appears

• Location: Main search results table and General Information tab of detailed view

• Format: Standard MM/DD/YYYY display

2. Certificate of Formation/Organization/Incorporation

• Sometimes stamped with Missouri Secretary of State seal and date

3. Filing history and confirmations

• References original filing date in the Filings tab

• Used to calculate annual report due dates and compliance requirements

Formation date vs. effective date

Missouri allows businesses to specify a future effective date when filing formation documents, creating two different dates:

• Formation date (file date): When the Missouri Secretary of State processed your paperwork

• Effective date: When your entity officially began operations (if you requested and received approval for a later date)

For most Missouri entities, the formation date and effective date are identical since businesses typically don't request delayed effectiveness. 

The business search portal displays the filing date as "Created Date," which represents when the state processed your formation documents. If you specified a future effective date when filing, that later date marks when your LLC officially began operations, though the Created Date still reflects the original filing.
