The official search
The registry is run by the Office of the Minnesota Secretary of State, Business Services, through the Minnesota Business & Lien System.
- Search page: https://mblsportal.sos.state.mn.us/Business/Search
- Cost: Free
- Login: None required to search (an online account is required to file)
The database covers corporations, LLCs, limited and limited liability partnerships, nonprofits, cooperatives, and assumed names (DBAs) registered under Chapter 333 — all in one system. That breadth matters, because Minnesota tests your LLC name against all of those records, not just other LLCs.
There is no separate yes/no availability tool for the public. The filing flow itself includes a name check, and you can buy certainty in a different way — a name reservation (below). For a free check, you judge availability from the Business Search results; the Secretary of State decides what counts as "distinguishable" when your filing is reviewed (§322C.0108, subd. 2). One caution printed on the portal itself: everything you put in a filing is public data that may be viewable online, including individual names and addresses.
A results list shows matching business names with their entity and name types (current legal name, former legal name, or assumed name). A detail record adds the file number, status (Active or Inactive), the statute chapter the entity is organized under, registered office and agent, formation date, renewal status, and filing history. Minnesota Articles of Organization do not list members or managers, so ownership is not on the public record.
Step by step
- Open Business Filings Online and choose Search Business Filings.
- Search by Business Name, without "LLC." Searching the bare name surfaces the same name across corporations, nonprofits, partnerships, and assumed names — all of which can block you.
- Run both a "Begins With" and a "Contains" pass (where offered), one on the full name and one on its most distinctive word, so near-misses built on the same word turn up.
- Check the status on anything close. An inactive record may still matter — names of terminated entities and reserved names are part of the distinguishability test, and a terminated LLC can reinstate retroactively.
- Search the assumed names too. Chapter 333 assumed names (DBAs) are inside the same system and inside the statute's test — a DBA can block an LLC name in Minnesota.
- If nothing distinguishable appears, the name is probably available — the Secretary of State's review of your filing is still the final word.
Minnesota's name rules
The rules are in Minn. Stat. §322C.0108 of the Minnesota Revised Uniform LLC Act.
Designator. The name must contain the words "limited liability company" or the abbreviation "LLC". That short list is the whole list — "Limited Company" and "LC" alone do not satisfy the Minnesota statute (professional firms organized under Chapter 319B follow a different section).
Prohibited terms. The name may not contain "corporation" or "incorporated," or any abbreviation of them, and may not contain a word or phrase implying the LLC is organized for a purpose it is not permitted to pursue. The name must also be expressible in English letters or characters.
Distinguishable. The name must be distinguishable upon the Secretary of State's records from the name of every domestic and foreign LLC, LLP, corporation, and limited partnership — profit or nonprofit — on file or authorized in Minnesota, and from every name reserved under the reservation statutes (§§5.35, 302A.117, 317A.117, 321.0109, 322C.0109) or filed as an assumed name (§§333.001–333.54). There are exceptions if the existing holder files written consent, if a court decree establishes your prior right, or if you file an affidavit that the conflicting entity has been on file at least three years and is not actually doing business — read the statute's exact conditions before relying on one.
Reserving a name. Under §322C.0109 you can reserve a name for one full year — unusually long — and renew it for additional one-year periods. The Secretary of State's reservation form lists the fee: $35 by mail, or $55 in person or online. A reservation does not register the business; it only holds the name.
What the search can't tell you
- A final verdict. The search shows records, not rulings. Distinguishability is decided by the Secretary of State at filing, and Minnesota's test is broader than LLC-vs-LLC.
- Trademarks and domains. The statute itself says the name rules do not limit trademark, trade name, or unfair-competition law. A clear state search is not trademark clearance, and it says nothing about .com availability.
- Who owns a company. Minnesota Articles do not collect member or manager names, so the public record will not identify an LLC's owners.
- Names in use but never filed. A business operating under an unfiled trade name leaves no trace in this system.
If the name looks available
File Articles of Organization (§322C.0201) with the Secretary of State — online through Business Filings Online (account required), in person, or by mail.
- Cost: $155 online or in person, $135 by mail. Minnesota's fee schedule prices the expedited channels higher, so the convenient route costs $20 more — the opposite of most states.
- What you file: essentially the name, registered office/agent information, and the organizer's details. No operating agreement and no member list is filed.
Ongoing: the free Annual Renewal. Every Minnesota LLC must file an Annual Renewal each year — and it costs $0.
- Due date: December 31, the same date for every LLC, starting the calendar year after the year you formed. Form in 2026 and your first renewal is due by December 31, 2027.
- There is no late fee, because there is no late filing. Miss December 31 and the Secretary of State administratively terminates the LLC under §322C.0208.
- Reinstatement is done by filing the missed renewal: $25 by mail or $45 in person/online on the Secretary of State's fee schedule. Do not rely on being able to fix it later — while terminated, the LLC is not in good standing and its name is exposed.
Set a recurring December reminder the day you form. A free filing is still a mandatory one.
FAQ
Is the Minnesota LLC name search free? Yes. Business Filings Online is free, and searching needs no account. You only need an account when you are ready to file.
How much does it cost to form a Minnesota LLC? Articles of Organization cost $155 online or in person, or $135 by mail, per the Secretary of State's fee schedule.
Does a Minnesota LLC file an annual report? Yes — an Annual Renewal, due every December 31 starting the year after formation. It is free, but missing it gets the LLC administratively terminated; there is no late fee or grace period.
Can I reserve my LLC name in Minnesota? Yes. A reservation under §322C.0109 holds the name for one year and can be renewed. It costs $35 by mail or $55 in person or online.
Why did my search find a corporation with my name? Does that block my LLC? Very likely, yes. Minnesota tests an LLC name against corporations, nonprofits, partnerships, reserved names, and assumed names — not just other LLCs (§322C.0108).
