Wisconsin Business Entity Search

You can search for a business either by name or ID. You also have the option of advanced search, where you can run complex queries based on multiple parameters.

Note: For checking business name availability, click on the ‘Name Availability’ tab next to the Search bar.

Basic Search – By Name/DFI Entity ID

Step 1: Open Wisconsin Department of Financial Institutions corporation search page – Link.

Step 2: In the search box, enter either the complete/partial name of the business or registered DFI entity ID of the business.

Search Tips:

  • Prefer to search by DFI ID. Searching by ID is faster and gives you more accurate results. DFI ID is of 7 characters containing one alpha character and six numeric characters. It can be in two formats: A###### or #A#####. Searching by valid DFI Entity ID will yield single result only.
  • If you are unable to find a business using the complete name, try entering the partial name of the business.
  • Don’t add any extension such as LLC or Corp or any punctuations.

Step 4: Click on the ‘Search‘ button.

Step 5: On the next page, you can view the search result. In the case of ‘Search by ID’, only one result will be shown.

If you encounter too many results, try searching again with a more precise search query or use the advanced search.

For instance, searching for ‘automobile repair‘ instead of just ‘automobile‘ yields 3 results instead of 77 results.

Step 7: Click on the desired business name to view more information.
