Michigan LLC Name Search

How to search for LLC names in Michigan

Searching the Michigan Department of Licensing and Regulatory Affairs (LARA) business entity database is a required first step before filing your LLC. The database displays all active and inactive business entities registered with the state, including corporations, LLCs, partnerships, and fictitious names. Running a search lets you confirm whether your proposed name is distinguishable from existing registrations, which Michigan law mandates. A name appearing available in the search tool is not a guarantee of approval — LARA staff make the final determination when they review your Articles of Organization. Identical names will be rejected outright, but names that are merely similar may also be refused if they could cause confusion. Searching early saves you filing fees and delays that come with a rejected application.

Step-by-step: using the Michigan Department of Licensing and Regulatory Affairs (LARA) name search

1. 1. Navigate to the LARA Corporations Online Filing System (COFS) search page at https://cofs.lara.state.mi.us/SearchApi/Search/Search.
2. 2. In the 'Entity Name' field, type your proposed LLC name — you can search a partial name or keyword to broaden results and catch similar names.
3. 3. Set the 'Entity Type' filter to 'Limited Liability Company' to narrow results to LLCs only, then click the Search button.
4. 4. Review the list of returned entities; click any result to view full details including status (Active, Dissolved, Revoked) and filing date.
5. 5. If no identical or confusingly similar name appears in the results, your name may be available — proceed to verify distinguishability and then file your Articles of Organization or reserve the name through LARA.

Michigan LLC naming rules

• The name must contain the words 'Limited Liability Company', the abbreviation 'L.L.C.', or 'LLC' — these designators are mandatory under Michigan's Limited Liability Company Act (MCL 450.4204).
• The name must be distinguishable upon the records of LARA from any other business entity already registered or reserved in Michigan — minor spelling differences or punctuation changes may not be sufficient to pass.
• The name cannot contain words that imply the LLC is a governmental body, such as 'State', 'Federal', 'United States', 'Municipal', or 'Congressional', unless authorized.
• Restricted professional terms — including 'Bank', 'Banking', 'Trust', 'Insurance', 'Cooperative', and similar financial or regulated-industry words — require prior written consent from the appropriate state regulatory authority before LARA will approve them.
• Terms suggesting a licensed profession, such as 'Engineer', 'Architect', 'Surveyor', or 'Physician', may require proof of licensure or board approval depending on context.
• The name cannot include obscene language, profanity, or words that are misleading about the nature or purpose of the business.
• The name may not include 'Corporation' or 'Corp.' as a standalone designator, as that implies a different entity type; however 'Incorporated' as part of a descriptive phrase unrelated to entity type may be permissible in limited contexts — confirm with LARA.
• Punctuation such as periods and commas is generally ignored when LARA evaluates distinguishability, so 'ABC, LLC' and 'ABC LLC' are treated as the same name.

Restricted words in Michigan LLC names

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

• Bank / Banking / Banker — requires approval from the Michigan Department of Insurance and Financial Services (DIFS)
• Insurance / Insurer / Assurance — requires prior written consent from DIFS
• Trust / Trust Company — requires DIFS authorization
• University / College — may require approval from the Michigan Department of Education or the relevant accrediting body
• Attorney / Law Office / Legal — context-sensitive; may require Michigan State Bar involvement if it implies a legal practice
• Engineer / Engineering — may require review by the Michigan Board of Professional Engineers
• Cooperative / Co-op — implies a specific legal structure and may require approval from relevant state agencies
• Lottery / Casino / Gaming — requires licensing approval from the Michigan Gaming Control Board

How to reserve an LLC name in Michigan

Michigan allows you to reserve an LLC name before filing by submitting a Name Reservation application (Form BCS/CD-540) to LARA with a $25 filing fee. An approved reservation holds the name exclusively for 180 days. Reservations cannot be renewed or extended — once the 180-day period expires, the name becomes available again. You must file your Articles of Organization before the reservation lapses to secure the name permanently.

Tips for choosing an LLC name that passes in Michigan

• Search both the exact name and keyword variations — LARA's distinguishability standard catches names that sound or look similar, not just identical matches, so run multiple searches with different word orders and abbreviations.
• Check the United States Patent and Trademark Office (USPTO) TESS database at tmsearch.uspto.gov to confirm your name does not infringe on a federally registered trademark, which the state search will not catch.
• Verify that your preferred domain name is available before committing to a business name — securing a matching .com domain protects your brand online and simplifies marketing.
• Avoid hyper-local geographic terms like a specific Michigan city or county in the primary identifier if you plan to expand, as they can limit perceived scope and may conflict with existing regional brands.
• Check Michigan's assumed name (DBA) filings as well, since a business operating under a trade name in your target market could still create confusion even if it is registered under a different legal name.
• Once you have a strong candidate name, reserve it immediately for $25 — this locks in the name for 180 days while you finalize your operating agreement, registered agent, and other formation details.
