How to Do a Business Name Search in Wisconsin and Choose a Name for your LLC
Starting an LLC in Wisconsin isn’t a complicated process, but it’s important to follow the required steps. One of the first steps is to select your business name and make sure it’s available for you to use.
Before you register your name, it’s essential to perform a business entity search. This makes sure the name you want is unique and complies with all applicable state regulations. The guide below will walk you through the process of performing a business entity search in Wisconsin, understanding the state’s naming guidelines, and determining the next steps once you’ve chosen an available name.

Why You Need to Perform a Business Entity Search When Starting an LLC
A business entity search involves checking the availability of a name in the state and it is required if you plan to register an LLC in Wisconsin. This is crucial for several reasons:
- Ensuring your chosen name is not already in use by another business.
- Avoiding potential legal issues related to trademark infringement.
- Complying with Wisconsin-specific naming regulations.
- Establishing a unique identity for your business.
State Naming Guidelines
Wisconsin has specific guidelines you must follow when choosing a name for your LLC:
- Uniqueness: The LLC name must be distinguishable from all existing businesses registered in Wisconsin.
- Required Words: The name must include “Limited Liability Company”, “LLC” or “L.L.C.”
- Restricted Words: Certain terms that can confuse your LLC with a government agency (e.g., “FBI,” “Treasury”) are prohibited unless you have permission from that agency.
- Prohibited Words: Terms like “bank,” “trust,” or any words suggesting an association with the financial industry are restricted unless you comply with additional regulatory requirements.
When it comes to restricted and prohibited words, it’s best to just avoid using them. For more detailed guidelines, visit the Wisconsin Department of Financial Institutions’ website.

Fictitious Name/DBA
If you plan to do business under a different name than your LLC, you should also search the fictitious name database to ensure your DBA name is not already being used.
What to Do Once You Have a Name That Is Available
Consider reserving your name
You can reserve your LLC name for up to 120 days by filing a name reservation application with the Wisconsin Department of Financial Institutions and paying the $15 fee. This secures the name while you take the other necessary steps to form your LLC.
The name reservation form is available for download on the Secretary of State’s website. It includes detailed instructions on how to complete it.
Consider trademarking your name
Registering your name as a trademark provides protection against name infringement throughout the U.S. Visit the USPTO website for more information on the trademark process.
Consider Registering Your Domain
Secure a domain name that matches your business name to establish your online presence.
