How to Search Colorado Business Entities
Step 1: Access the Official Colorado SOS Website
Navigate to the official Colorado Secretary of State business entity search portal at sos.state.co.us/biz/BusinessEntityCriteriaExt.do or coloradosos.gov/biz/BusinessEntityCriteriaExt.do. You can also access it through co.colorado.gov/search-business-records or sos.state.co.us/ucc/pages/biz/bizSearch.xhtml. These are the free, government-operated databases for all Colorado business entities.
Step 2: Choose Your Search Method
Select how you want to search: by entity name (most common), entity ID number, document number, or registered agent name. The entity name search allows partial matches and is the most frequently used method for finding Colorado businesses. You can also search by city or zip code.
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. Colorado's search is case-insensitive and supports wildcard searches 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 entity ID number. Click on a result to view detailed information. Colorado's database typically shows multiple results if there are similar business names, so review carefully.
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The detailed view shows registration date, current status (Active, Dissolved, Merged, Withdrawn), registered agent name and address, principal office address, officers and directors, entity ID number, document history, and filing history including annual reports and amendments. Verify all information matches what you expect.
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 If it shows 'Dissolved', 'Merged', 'Withdrawn', or 'Revoked', the business may not be in good standing with the state.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. Colorado has very business-friendly fees with low annual report costs.
