How to Search Missouri Business Entities

1

Step 1: Access the Official Missouri SOS Website

Navigate to the official Missouri Secretary of State business entity search portal at sos.mo.gov/business. You can also access it through sos.mo.gov/business/corporations for corporation-specific searches. This is the free, government-operated database for all Missouri business entities including corporations, LLCs, and partnerships.

2

Step 2: Choose Your Search Method

Select how you want to search: by business name (most common), charter number, or registered agent name. The business name search allows partial matches and is the most frequently used method for finding Missouri businesses. You can search for corporations, LLCs, limited partnerships, and other business entities.

3

Step 3: Enter Search Criteria

Type the business name in the search field. Try variations: with and without business suffixes (LLC, Inc, Corp, L.L.C.), partial names if exact match doesn't work, and check for common abbreviations. Missouri's search is case-insensitive and supports partial name matching for more flexible results.

Step 4: Review Search Results

Browse the results list to find your business. Each result shows the entity name, type, status, and charter number. Click on a result to view detailed information. Missouri's database typically shows multiple results if there are similar business names, so review carefully to find the correct entity.

Step 5: View Detailed Entity Information

The detailed view shows registration date, current status (Active, Dissolved, Merged, Withdrawn), registered agent name and address, principal office address, officers and directors, charter number, and filing history including annual reports and amendments. Verify all information matches what you expect for the business you're researching.

6

Step 6: Verify Business Status

Check that the business status is 'Active' or shows 'Good Standing'. If it shows 'Dissolved', 'Merged', 'Withdrawn', or 'Revoked', the business may not be in good standing with the state. Active status indicates the business is current with all required filings and annual reports. Missouri requires annual reports to maintain active status.
