Minnesota's 12-month hold is one of the longest in the country, and it is renewable for successive 12-month periods — you can effectively park a name indefinitely.
How Business Name Availability Works in Minnesota
Minnesota runs business filings through MBLS — the Minnesota Business and Liens System — and its name search is free. The search covers domestic and foreign entities, limited liability partnerships, limited partnerships, assumed names, and reservations, which is exactly the set your proposed name will be tested against.
Two things make Minnesota naming distinctive. First, the LLC statute is unusually terse: Minnesota Statutes § 322C.0108 lists only two designators — "limited liability company" or "LLC." No "L.L.C.," no "Limited Company," no "Ltd. Co." Second, the name reservation is one of the most generous anywhere: $35 by mail or $55 online buys a full 12-month hold, renewable for successive 12-month periods.
If you plan to trade under a brand different from your legal name, budget for Minnesota's old-school assumed-name process: the Certificate of Assumed Name ($30 mail / $50 online) must be published in a qualified legal newspaper for 2 consecutive issues, and then renewed every year — the renewal is free, but skipping it voids the registration.

How to Check Name Availability in Minnesota
Use the tool above to open the Minnesota Secretary of State — Business Filings Search search and look up existing LLCs, corporations, and reserved names. Minnesota assumed names must be renewed every year — the renewal is free, but miss it and the registration lapses. The free-but-mandatory renewal catches more founders than the fee ever would.
Search the USPTO database at uspto.gov — clearing the Minnesota registry does not protect you from a federal trademark claim.
Check that the matching .com domain is available before you commit — renaming an LLC later means an amendment filing and new bank paperwork.
Confirm your name is free on Instagram, X, Facebook, and LinkedIn so your branding stays consistent everywhere.
Minnesota lets you reserve a name for 12 months for $35 by mail, $55 online or in person — Filed through the MBLS online system or by paper with the Secretary of State.

Searching Minnesota Names Through MBLS
The Secretary of State's MBLS portal offers a free business name search across corporations, LLCs, LLPs, LPs, assumed names, and reserved names. Because reserved names count against availability, a name can be blocked by someone who has not even formed a company yet — MBLS shows those holds.
Minnesota applies a "distinguishable upon the records" standard: your name needs to differ in some real way from everything on file. Changing punctuation, spacing, or the entity designator does not create distinguishability; adding or changing a key word does.
When the search comes back clean, you have two moves: file the Articles of Organization ($155 online) and take the name, or reserve it. Given that Minnesota's reservation lasts 12 months and renews indefinitely, it is one of the few states where reserving early is genuinely worthwhile for a slow-burn launch.
Minnesota Naming Rules: Only Two LLC Designators
Minnesota Statutes § 322C.0108 lists exactly two acceptable LLC designators: "limited liability company" or "LLC." Most states accept a half-dozen variants; Minnesota's statute names only these two, so do not plan a logo around "L.C." or "Ltd. Co."
Corporations follow § 302A.115: the name must contain "corporation," "incorporated," "limited," or "company" — with the classic caveat that "company" may not be immediately preceded by "and" ("Lund and Company" fails; "Lund Company" passes). Corporate names must be in English letters or characters.
The availability test runs against domestic and foreign entities, LLPs, LPs, and reserved names on the Secretary of State's records. Words implying banking, insurance, or a licensed profession trigger review by the Minnesota Department of Commerce or the relevant licensing board.
Assumed Names in Minnesota: Publication Required, Renewal Free
Minnesota's DBA — the Certificate of Assumed Name under Minnesota Statutes chapter 333 — costs $30 by mail or $50 online. Any person or entity doing business in Minnesota under a name other than its full legal name must file one.
The filing is only step one. Minnesota still requires newspaper publication: the certificate must run in a qualified legal newspaper for 2 consecutive issues in the county of your principal place of business, and you keep the affidavit of publication. Skip publication and the registration is not complete.
Then comes the trap: Minnesota assumed names require an annual renewal. The renewal is free — the Secretary of State just needs the filing — but because nothing is owed, founders routinely ignore the notice and let the registration lapse. Calendar it like a tax deadline.
