When we search the registered names, we get a list of all the businesses with the words “Lawn & Order.” To register a corporation or LLC name in Wisconsin, the name must be distinguishable from the other registered names. If you were looking to form an LLC with this name, you wouldn’t be able to since there is already one registered.

While the company name “Lawn & Order” by itself may not be available, other variants such as “Wisconsin Lawn & Order.”  Searching for this business name brings a result that says, “Sorry, your search returned no records.”  Even if the name looks like it is available, the Department of Financial Institutions will do its own search to avoid confusing potential customers with a business name that sounds like someone else’s.  Typically words that sound alike but are spelled differently, and even abbreviations will make names show up as available but won’t be approved.

Wisconsin Business Name Availability

These are the basics of searching for a business name in Wisconsin.  Even when the name of the business you want looks like it is available, the Department of Financial Institutions will make a final determination at the time of filing to ensure the name you picked isn’t too similar to other registered names. 

What information can be found on the Wisconsin business entity database?

The Wisconsin business search can find several pieces of information about the business. Some of the highlights include:

  • Business Name
  • Registered Effective Date: The date the entity was first filed with the Department of Financial Institutions
  • Status: Organized means the entity is in good standing, and all reports and filing fees are up to date. Other results include “Administratively Dissolved,” “Dissolved,” Delinquent,” and “Involuntarily Dissolved.” The names of these inactive results may be available to register.
  • Entity Type: Corporation, Limited Liability Company, etc.
  • Registered Agent’s information:Wisconsin registered agent is the singular point of contact for the entity should a legal, or tax notice need to be sent to the business.  This is often one of the owners, and if their home address is used, that address becomes public information.  Many people find this concerning and use a Registered Agent service like Northwest Registered Agent, so their home address isn’t listed.  

Wisconsin Business Name Search FAQs

How do I find a name for a Wisconsin sole proprietorship?

The Department of Financial Institutions Business Entity Database provides information on corporations and LLCs registered in Wisconsin, but the names of sole proprietorships and general partnerships are not available here. Instead, they are registered with the County Clerk’s office in the county where the business is located. 

To register, a sole proprietorship or partnership operating their business under a name that is different from the owner’s legal name will register for a Fictitious Business Name, which is also known as “Doing Business As,” DBA, Assumed Name, or Trade Name.
