Wisconsin lesson 1 of 6
Name your Wisconsin LLC
DFI will reject an Articles of Organization filing if the proposed name is not distinguishable from a name already on its register, so search the entity database before you submit.
Required wording
A Wisconsin LLC name must contain the words limited liability company or the abbreviation LLC or L.L.C. Wording that falsely implies the LLC is a government agency, or that it is organized for a purpose other than one stated in its Articles, is not permitted.
- Acceptable: Badger Ridge Contracting LLC, Badger Ridge Contracting L.L.C.
- Avoid words suggesting a bank, trust, or insurance company without the required state approval
- Certain professional and regulated terms may require sign-off from the relevant licensing board
Checking availability and reserving a name
Search the DFI online business entity database before filing. Wisconsin uses a distinguishable-on-the-record standard, so punctuation, spacing, or a generic designator alone usually will not separate your proposed name from an existing one.
If you are not ready to file the Articles of Organization yet, you can reserve a name with DFI for a fee, which holds it for you rather than leaving it open to another filer.
Trading under a name different from the one in your Articles is a separate filing in Wisconsin, made with DFI rather than at the county level.
🇺🇸 Check United States company name availability
Search the official United States state registry before you file. Opens the government portal in a new tab.
Tip: also confirm the .com domain and matching social handles are free before you commit.
Key takeaways
- End the name with LLC or L.L.C., or the words limited liability company in full.
- Search the DFI business entity database before filing.
- A paid name reservation with DFI holds a name before you are ready to file.
