Check LLC Name Availability in Wisconsin

You can use Wisconsin’s Business Entity Search to check the availability of your desired name.

To perform the most effective search, type in the name you would like to use, excluding identifiers like “LLC.” This will return all entities using the same or similar names. If your business name is several words, you can even search just the first two words to ensure you pull up all possible similar names. Wisconsin also offers a specific Name Availability Search.

Be sure to conduct a thorough search before completing your paperwork to avoid rejection.

2. Search Available Domain Names

Another important consideration to make when selecting a business name is whether or not your desired web domain name is available.

Having a URL that clearly matches your business name is important. This seemingly small step can make a big difference in how prospective customers find your business.

The best way to determine if your desired URL is available is to search for it online using your preferred domain registry, such as GoDaddy.

3. Follow Wisconsin Naming Guidelines

When forming a limited liability company (LLC) in Wisconsin, choosing the right name is crucial. This section provides an overview of the naming requirements and guidelines to help you select a unique and distinguishable name for your LLC.

Permitted Names

To comply with Wisconsin law, the name of your LLC must include one of the following phrases or abbreviations:

  • "Limited Liability Company" or "Limited Company"
  • "LLC" or "LC"

Additionally, you may use variations of these abbreviations, differing only in capitalization or punctuation. You can also abbreviate "Limited" as "Ltd." and "Company" as "Co."

Distinguishing Names

To ensure that your LLC's name is distinguishable from others on record, it must not be confusingly similar to any of the following:

  • Names of existing individuals that required filing with the Department of Financial Institutions and are not administratively dissolved
  • Names of registered limited liability partnerships (LLPs)
  • Names under which a person is registered to do business in Wisconsin
  • Reserved names filed under state laws
  • Names registered under state laws

Authorization for Nondistinguishable Names

In certain cases, you can apply for authorization to use a name that is not distinguishable from other registered names. The Department of Financial Institutions may grant authorization if:

  • The entity with the conflicting name provides written consent and undertakes to change its name or cancel its registration/reservation
  • You provide a certified copy of a court judgment establishing your right to use the name

Prohibited Language

The name of your LLC should not imply that it is organized for a purpose subject to regulation under another Wisconsin statute unless the purpose is permitted by that statute and the entity complies with its limitations.

Ensure you follow these naming requirements to select an appropriate and available name for your Wisconsin LLC. Conduct a thorough search and ensure your chosen name complies with the guidelines before proceeding with the registration process.

Other Considerations

While reserving an entity name for your Wisconsin LLC is straightforward, there are some other things you should think about when choosing the best name for your business. You may want to do a Trademark and Social Media search for your entity name to see if it's available for use online. This will help ensure you have full, unrestricted use of your business name.

Trademark Search

Conducting a trademark search of your entity name and associated slogans or logos before registering can help prevent costly litigation in the future. Discovering that another entity has trademarked your business name does not automatically disqualify you from using it.

However, it is important to know who is using the name, what industry they operate in, and where they are located to be sure you do not inadvertently infringe upon anyone’s intellectual property rights.

To complete this step:  

Social Media Search

Just as important, or more so, than finding a domain name that fits your business is ensuring that your business name is available for use across online social media platforms. To do this, search for your business name on each major site, using a tool such as Namecheckr to search across all platforms at once.

Bottom Line

Having a name for your business is an important first step for creating a successful LLC, and one that is incredibly easy to do. Once you have found your preferred entity name using Wisconsin's Business Entity Search, you'll want to secure your domain name so that your customers will be able to find your business online.

Reserving your entity name with a Name Reservation Application Form will help you stand out from the competition. With your name secured, you will be ready to take the next steps to formalize your Wisconsin LLC.
