Minnesota LLC Name Search

How to search for LLC names in Minnesota

Searching for an available LLC name in Minnesota is a required step before submitting your Articles of Organization to the Minnesota Secretary of State. The state maintains a publicly searchable database of all registered business entities, including LLCs, corporations, and limited partnerships. Running a name search through the Minnesota Business and Lien System (MBLS) portal shows you every active and recently dissolved entity on file, so you can identify potential conflicts before paying filing fees. Keep in mind that finding no exact match does not guarantee your name will be approved — the Secretary of State reviews whether your proposed name is "distinguishable" from existing names, a standard that catches close variations, not just identical matches. Checking the database yourself is the first step, but approval happens only at the time of filing.

Step-by-step: using the Minnesota Secretary of State name search

1. 1. Navigate to the Minnesota Business and Lien System (MBLS) portal at https://mblsportal.sos.state.mn.us/Business/Search using any web browser.
2. 2. In the 'Business Name' field, type the name you want to use for your LLC — you can enter a full name, a partial name, or key words; leave the entity type filter set to 'All' for the broadest search results.
3. 3. Click the 'Search' button and review the list of results, paying close attention to names that are spelled similarly, sound alike, or use common abbreviations of your proposed name.
4. 4. Click on individual entity names in the results list to view their full record, including current status (active, dissolved, inactive) and entity type, so you can assess whether an existing registration would block your filing.
5. 5. Repeat the search using variations of your name — plurals, abbreviations, different word orders, and alternate spellings — because the Secretary of State evaluates distinguishability broadly and may reject names that differ only in minor ways from an existing registration.

Minnesota LLC naming rules

• Your LLC name must contain the words 'Limited Liability Company,' the abbreviation 'LLC,' or 'L.L.C.' — no other designators are acceptable under Minnesota Statutes Section 322C.0108.
• The name must be distinguishable upon the records of the Secretary of State from all other registered business names in Minnesota, meaning it cannot be identical or deceptively similar to an existing entity name.
• Your LLC name cannot contain language that implies the business is a governmental agency, subdivision, or instrumentality — terms like 'Department of,' 'Bureau of,' or 'State of Minnesota' are not permitted.
• Certain words suggesting regulated professional or financial services — such as 'Bank,' 'Banking,' 'Insurance,' 'Trust,' 'University,' or 'College' — require prior written authorization from the applicable state regulatory agency before the Secretary of State will accept the filing.
• The name cannot include obscene, deceptive, or fraudulent language, and it cannot mislead the public about the nature, purpose, or activities of the business.
• If you wish to use a name that includes a professional title such as 'Attorney,' 'Doctor,' 'Engineer,' or 'Architect,' the LLC must be organized as a professional limited liability company (PLLC) and the members must hold the appropriate state license.
• The name may contain special characters and punctuation — such as ampersands or hyphens — but the Secretary of State treats these as equivalent to spaces or letters when evaluating distinguishability, so such variations will not make an otherwise conflicting name acceptable.
• Foreign LLCs (those formed outside Minnesota) that register to do business in the state must use a name that meets all the same naming requirements, and if their legal name is already taken in Minnesota, they must adopt an alternate name for use in the state.

Restricted words in Minnesota LLC names

The following words require special approval from a state agency before you can use them in your Minnesota LLC name:

• Bank / Banking / Banker / Bankers — requires approval from the Minnesota Department of Commerce
• Insurance / Insurer / Underwriter — requires written authorization from the Minnesota Department of Commerce
• Trust / Trust Company — requires approval from state banking regulators
• University / College / Academy — requires authorization from the Minnesota Office of Higher Education or relevant accrediting body
• Attorney / Lawyer — permissible only in a licensed Professional LLC (PLLC) with attorney members
• Doctor / Physician / Medical — permissible only in a PLLC whose members hold valid Minnesota medical licenses
• Engineer / Engineering — may require authorization depending on context; professional engineering PLLCs are regulated by the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience and Interior Design
• Cooperative / Co-op — implies a specific legal structure under Minnesota cooperative statutes and should not be used by a standard LLC

How to reserve an LLC name in Minnesota

Minnesota allows you to reserve an LLC name for 12 months by filing an Application for Reservation of Name with the Secretary of State. The filing fee is $35 online or $55 for paper submissions. You can file online through the MBLS portal. The reservation holds the name exclusively for you during that period. Minnesota does not offer a renewal or extension — if you need more time, you must file a new reservation application and pay the fee again before the original reservation expires.

Tips for choosing an LLC name that passes in Minnesota

• Search for your exact proposed name first, then run additional searches using common abbreviations, alternate spellings, plurals, and phonetically similar words — the Secretary of State can reject a name that merely sounds like an existing one.
• Check the United States Patent and Trademark Office (USPTO) TESS database at tess.uspto.gov to ensure your chosen name does not infringe on a federally registered trademark, since state approval does not protect you from trademark infringement claims.
• Verify domain name availability for your business name before filing — registering yourname.com or .co early prevents a competitor from claiming it after your LLC goes public in state records.
• Avoid names that are overly geographic (e.g., 'Minneapolis Tech LLC') if you plan to expand to other markets, as geographic descriptors can limit your brand and may conflict with locality-specific names already on file.
• Consider how your name will appear in searches and directories — short, distinctive names with no common words are less likely to conflict with existing registrations and are easier for customers to find online.
• If you plan to operate under a name different from your registered LLC name, file a Certificate of Assumed Name (DBA) with the Minnesota Secretary of State — this does not replace the name search requirement but allows you to use a trade name publicly.
