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."
Contact the WDFI Division of Corporate and Consumer Services at 608-261-7577 or visit the office to request a search of business names to verify their availability. Office hours are Monday - Friday 7:45 a.m. - 4:30 p.m.

Visit your library to review Wisconsin business directories to determine if the business name you want is available. Contact your local chamber of commerce to request a list of all registered businesses in your area and throughout the state. Some chamber of commerce websites include a directory of registered businesses.
Download a Name Reservation Application from the WDFI website. Include the business name you intend to use. You may reserve a business name for up to 120 days. A fee of $15.00 for LLC's, cooperatives and foreign business corporations or $10.00 for domestic and foreign for-profit and nonprofit corporations and limited partnerships is required.
