Registered business names cannot be used by other business entities in the state of Wisconsin. If you submit a business name already registered, all business filing paperwork will be returned. Before submitting business filing paperwork, conduct a business name availability search using search tools provided by the Wisconsin Department of Financial Institutions and by conducting your own searches using local business directories and other resources found at your local library, chamber of commerce or local small business administration office.
Conduct a search of registered business names using the Wisconsin Department of Financial Institutions Corporate Registration Information System (CRIS). Click "Name Availability" and enter the business name in the open field. Click "Search Records."
