Interpreting Search Results

If the results in the search show names that aren’t similar to yours, then your LLC name is available. For example, if your LLC name is Riverwalk Studios LLC and the only name that comes up in the search is Riverwalk Rentals, your name is available.

If no results show up, then your LLC name is unique, and your name reservation can be completed. To double-check, you can run your name availability search again with only part of your LLC name.

If your exact LLC name is on the list, then that name is not available because another Wisconsin LLC is using that name.

If your LLC name isn’t available, you will have to come up with another name for your business or a different variation of your chosen name.
