Business Entity Search

The Wisconsin LLC lookup is a search database provided by the Secretary of State. You can use this search to see if the preferred name of your limited liability company (LLC) is taken by another Wisconsin business. This tool allows users to find the details of any cooperative, limited partnership, limited liability partnership, or corporation registered with the state. Businesses can also use it to submit their annual reports, file registered agent and office update forms, or obtain a Certificate of Status. 

A business entity search can tell you the following details about a business:

Understanding the Wisconsin Business Entity Search System

The Wisconsin business entity search is a public database maintained by the Wisconsin Department of Financial Institutions (DFI). It provides up-to-date records for all registered business entities, including LLCs, corporations, limited partnerships, and cooperatives. This system helps users determine whether a business name is available, verify the legitimacy of a company, or review essential compliance filings.

When you search an entity, you’ll find:

  • Legal name and entity type (LLC, corporation, etc.)
  • Formation date and state ID number
  • Registered agent’s name and address
  • Status (active, delinquent, or dissolved)
  • Filing history, including annual reports and amendments

The Wisconsin DFI’s entity search is particularly useful for confirming whether a business is authorized to operate within the state. You can also download official documents such as a Certificate of Status, which is often required for banking, licensing, or interstate registration purposes.

Search by Name

Searching by the organization name is the most common method of finding an LLC. You can also search by registered agent or check the availability of a name. Checking name availability can help you choose the right name for your Wisconsin LLC. 

Enter the name you plan to use; then click "Search Records." Use additional keywords that will return similarly named businesses. You'll receive a list of all businesses that match the terms you entered in alphabetical order. Each listing includes:

  • The company's identification number
  • Type of business entity
  • The date it was formed
  • The date the information was last updated. 

Click on the name to learn more information about that business. You'll receive all the information published by the Department of Financial Institutions. This includes:

  • Annual reports
  • The name and address of the registered agent
  • The company's legal status. 

On your company's page, you can request a Certificate of Status, file your annual report, and update your company's information.

Other Search Methods and Advanced Filters

While searching by name is most common, the Wisconsin business entity search also allows alternative search methods for more targeted results:

  • Search by Registered Agent: Enter the name of a registered agent to view all entities they represent in Wisconsin. This is helpful for law firms, corporate service providers, or business owners managing multiple LLCs.
  • Search by Entity ID: Each business has a unique ID assigned by the DFI. Using this number provides precise, single-entity results.
  • Search by Filing Type: Narrow your search to specific filings such as amendments, mergers, or dissolutions.

If your search returns many similar results, you can refine it using partial keywords or the “begins with” filter. Always review the entity status to confirm whether the business is currently in good standing with the DFI.

Recent updates to Wisconsin’s LLC laws under Chapter 183 (WULLCL) now require greater accuracy in public filings and operating agreements. This makes the entity search a vital tool for ensuring your business information remains compliant with state law.

Search for Name Availability

After you do a name availability search and confirm the name you want is available, make sure the name is available as a URL. Purchase the domain so you'll be able to use it when you're ready to make a website. You'll also need a professional email address, such as [email protected]. You can set this up through a company such as Google apps, which also provides business tools, security, and cloud storage.

Tips for Choosing and Registering Your Wisconsin LLC Name

After confirming name availability through the Wisconsin business entity search, make sure your chosen name complies with the state’s naming rules. The name must:

  • Include “Limited Liability Company,” “LLC,” or “L.L.C.”
  • Be distinguishable from other registered business names
  • Avoid restricted terms such as “bank,” “insurance,” or “trust” unless authorized

Once you find an available name, it’s recommended to reserve it through the DFI (optional but beneficial) and secure a matching domain name for your website.

If your preferred name is unavailable, you can modify it slightly—for example, by adding geographic or descriptive words (e.g., “Madison Builders LLC” or “Superior Tech Solutions LLC”).

Because Wisconsin’s LLC laws have recently been updated, business owners should also review how these changes affect operating agreements and ownership rights.
