BEST PHONE CALL IN THE 364.25 DAYS OF 2025
Wow! Being nervous and not knowing exactly which direction to take I went online last night and found LegalZoom. I wasn’t completely sure about it (getting the LLC) and my anxiety kicked in so I backed out of it. My number must have saved anyway in their archive because I received a call this morning. Martha Anguiano called and the encounter with her was just what I needed to encourage me further with my LLC process. She was very polite, knowledgeable and immediately gave me a list of what I can choose from to start. After discussing with her more about my plans she suggested the best start up package for me. Martha was so genuinely enthusiastic about my idea that I felt truly comfortable sharing with her. After getting off the phone my smile and heart expressed the connection that was made even if it’s only for the professionalism she offers as an agent, I’m grateful it was her that called as I stated to her, “I’m not sure how it would have went if it were another agent that called.” (I can be nervous when speaking and studdar my words but she made me feel completely heard and understood) I can only hope and believe the entire Team at LeagalZoom is just as pleasant, knowledgeable and concerned for the customers as she exemplified. If you see this message Martha, thank you so much you’re definitely a Golden Star in this universe. ⭐️✨⭐️ Looking forward to working with you & LegalZoom. Thank You!

Key takeaways
Before you formally register your business in Wisconsin, perform a business name search to see if your first choice is available in the state.
All Wisconsin business entity searches and filings are done through the Wisconsin Department of Financial Institutions (WDFI), not the Secretary of State.
If your business name isn’t distinguishable from others currently in use, the WDFI could reject your registration filing.
LegalZoom’s free business name search helps you do a preliminary check of the WDFI database to see if your preferred name seems to be available.
Get into the details of a Wisconsin name search below, and learn more business names and registration in The Badger State.
Why does a Wisconsin business name search matter?
With business name registration, don’t take a “wait and see” approach. If you don’t confirm whether your preferred name is available before you file formation paperwork, the WDFI can reject it, causing you to resubmit and pay for another registration filing.
Instead, do a little legwork ahead of time by running a business name search before you register. With a name search, you can help confirm that your desired name is available for reservation and registration before you file, leading to a seamless formation experience.
Example: If “Madison Marketing Group LLC” is already registered, a name like “Madison Marketing Group Inc.” would likely be rejected, as different designators don't constitute distinguishability in Wisconsin.
Who needs to conduct a Wisconsin business name search?
If you plan on operating a business in Wisconsin, you should conduct a business search before registering with the WDFI. Here’s who that includes:
Corporations and limited liability companies (LLCs). These entities must include entity designators, like “Corp.” or “LLC.”
Nonprofit corporations. Nonprofits must register with the state to qualify for tax incentives and adhere to the same rules as other entity types.
Limited partnerships (LPs) and limited liability partnerships (LLPs). LPs and LLPs formally register with the WDFI and must make sure that their names are distinguishable from others on record.
General partnerships and sole proprietorships. General partnerships and sole proprietorships are not required to register in Wisconsin. However, if the owners decide to operate under a name different from their legal name, they must apply for a “doing business as” (DBA) name—called a “trade name” in Wisconsin. These names are subject to the distinguishability requirement as formal entity types.

How to conduct a Wisconsin business name search
There are a few ways to conduct a Wisconsin business name search.
Use LegalZoom’s business name lookup tool
LegalZoom’s business name check tool is free and allows for unlimited searches. With our tool, you can easily look up names on file with the DFI. All you have to do is type in your desired name, choose the business entity type, and click “Check Availability.” The tool combs the WDFI database for similar names and tells you whether your business name is available or not.
Run checks for variations of the name including different spellings, pluralizations, and more to ensure that you cover all your bases.
Search Wisconsin’s state records
You can also search name availability on the WDFI’s website.
Step 1: Visit the state’s name availability search portal. Head to the WDFI’s specific Name Availability search option through its Corporate Records database.
Step 2: Enter your search criteria. Type in the name you’d like to search, such as “Lakeside Designs.” Click “Search Records.”
Step 3: Review results. The tool will tell you if any WDFI records appear to conflict with your name or not. If there are conflicting records, you’ll be able to click to view the existing business with the same or similar name.
Step 4: Conduct an advanced search. If you’d like, you can perform an advanced WDFI Corporate Records search. At the top of the results page or on the portal’s home page, select “Advanced Search.” You’ll be able to enter your search criteria, choose what results you want to see (e.g., exact phrase, name contains, etc.), choose the entity status (e.g., in existence or no longer in existence), and more.
TIP: Wisconsin provides the option to call the Corporation Bureau and have an agent perform a name availability search for you. This can give you an extra sense of security about your name availability. You can reach the Corporation Bureau at (608) 261-7577.
How to conduct a trademark search for your Wisconsin business name
While a business name check tells you if a name is available for reservation or registration in Wisconsin, it doesn’t tell you if it infringes on any trademarks. That’s why it’s crucial to conduct a trademark search to ensure that you’re abiding by state and federal trademark protections.
Search for free with LegalZoom. LegalZoom’s Free Trademark Search checks the U.S. Patent and Trademark Office (USPTO) database for names that match your search criteria exactly. If the tool shows that your name is already trademarked, continue searching other names or variations of your preferred name. You get as many searches as you’d like—free!
Go beyond the basics with LegalZoom’s comprehensive trademark search. Our Comprehensive Trademark Search executes a full-scope search of existing and pending marks with the USPTO and provides ranked results to help pinpoint potential conflicts. You can select between a federal search and a combined federal, state, and common law search, based on your specific needs.
When you’re ready to register your trademark, turn to LegalZoom’s Premium Trademark Registration service—the #1 trademark filer with the U.S. Patent and Trademark Office. 1

Other searches you should run before registering your Wisconsin business name
Checking the WDFI’s Corporate Records database is a great—and necessary—place to start, but there are other types of searches you should perform before formally registering your business.
USPTO trademark search
Remember that state business registration only protects the use of your business name by other companies operating in Wisconsin. That means that your business name may or may not be trademarked at the national level.
To avoid infringing on pending or existing federal trademarks, perform a search through the USPTO’s trademark database, or use LegalZoom’s free trademark search tool, which combs the USPTO database for you, letting you know if your name is available or not.
With a USPTO trademark search, you can also look up other types of brand assets, including:
Taglines
Logos
Brand-specific symbols
If your name is trademarked, you unfortunately won’t be able to use it. This is where your backup options come in handy. You’ll need to keep searching until you find a name that hasn’t been trademarked.
Wisconsin trademark search
It’s also important to conduct a state trademark search to ensure that your business name doesn’t infringe on state trademark protections. You can either use LegalZoom’s Comprehensive Trademark Search tool, which performs federal and state trademark and common law searches. Alternatively, you can search the WDFI’s trademark database, which shows all active and expired trademarks in Wisconsin.
Domain name search & social media search
An online presence is important for any business to grow and thrive—yours included. Setting up a website and social media profiles is a great step to start marketing your Wisconsin business. Even if you’re not quite ready to launch your online presence, you can still check that your business name is available to reserve. This can be a helpful step even before you register with the WDFI. Here’s what to look up:
Existing businesses on the internet. See if your business name pops up on popular search engines, such as Google, Bing, and Yahoo. If similar or exact names exist in top results, it may be worth choosing a variation of your preferred business name just to stand out.
Domain name availability. To build a website, you’ll need a unique domain name. Check domain name registrars, like GoDaddy and Squarespace, to see if your business name is available. If it is, purchase it as soon as possible to keep others from taking it.
Social media handle availability. Do a search on social media platforms where you might create business profiles, such as Instagram, Facebook, and YouTube, to check if your business name is available as a handle.
These online searches pave the way for you to launch a digital presence for your brand, which helps ensure continuity between your business name and online brand assets.
What to do after a Wisconsin business name check
Now that you’ve verified that your business name is available, you can start the registration process:
Register your business with the Wisconsin Department of Financial Institutions. You can submit formation paperwork directly with the WDFI, but for the easiest, most seamless method, use LegalZoom’s formation service to start your Wisconsin business with confidence. You can also reserve your business name for 120 days.
Register a DBA (called a trade name in Wisconsin) if you plan on operating under a different name from the one listed on your formation documents.
What to do after you’ve registered your business name
Reserve a domain name and social handles
Reserve a domain name and social handles
Your online presence is just as important as your storefront. Here’s how to secure it:
Claim your domain name
Choose a domain that matches your business name as closely as possible.
Check social media availability
Platforms like Instagram, Facebook, and LinkedIn are key for connecting with customers.
Think long-term
Even if you don’t plan to use all platforms right away, securing them now ensures you won’t lose them later.
Protect your brand with a trademark
Protect your brand with a trademark

Enforces your rights in court if necessary.

Demonstrates professionalism and trustworthiness.

How to find information about an existing Wisconsin business
There may be instances in which you need to find information about a business registered in Wisconsin. Depending on what you’re looking for, you can use the following methods.
Use an employer identification number (EIN)
To check a company’s credit and financial details, you’ll need their EIN, which is a federal identification number for businesses. But looking up a company by their EIN can’t be done with a Wisconsin business entity search. Instead, you’ll need to use the following search methods:
Use a third-party service. You can look up Wisconsin businesses with an EIN through data and analytics companies like Dun & Bradstreet. You may be charged a fee to perform this type of search.
Conduct a search with credit bureaus. You can gather financial details about a business by reaching out to credit reporting bureaus. For example, an Experian Business Credit Report lets you check a company’s financial and legal standing.
These types of business searches are helpful for gaining insights into a company before investing in or partnering with them.
Reach out to the registered agent
Wisconsin business entities that register with the WDFI are required to designate and maintain a registered agent, who acts as the business’ legal point of contact. Here’s how to perform a Wisconsin registered agent lookup.
Step 1: Find the agent. Enter the company’s name in the WDFI’s business entity search tool. On the results page, select the business you’re looking up. On the business’ profile page, under “Addresses,” find the agent name and address.
Step 2: Contact the agent. Reach out to the agent at the address on file. You can contact the registered agent if you have legal business with the company or would like more information about the business.
Contact a company’s registered agent when you have legal business or need to deliver legal documents.
LegalZoom can help you file your state's formation paperwork and get your business on the right track.
Frequently asked questions
Is a Wisconsin business name search free?
Yes, both the Wisconsin DFI name availability search and the LegalZoom business name search tool are free to use.
Can I use the same name as a dissolved Wisconsin business?
If a Wisconsin business is dissolved, you may be able to register its name. This option isn’t guaranteed, though, so it’s best to contact the Wisconsin DFI at (608) 261-7577 to confirm whether the name can be used before you attempt to register it.
Does my Wisconsin LLC name need to be unique nationwide?
No, Wisconsin LLC names only need to be unique in the state itself. However, if there is a federal trademark on your preferred name, you may not be able to use it even if it's available for registration in Wisconsin. Always run a USPTO trademark search in addition to a Wisconsin LLC search.
What happens if my Wisconsin LLC name is rejected after filing?
If your Wisconsin LLC name is rejected after filing, you’ll need to choose a different name and resubmit your formation paperwork with the DFI, along with paying the filing fee again. That’s why it’s a good idea to perform a Wisconsin business name search before you register with the DFI.
