How to Do a Michigan LLC Name Search (2026 Guide)

Last Updated April 30, 2026 by the LLCForge Editorial Team. Verified against current state filing data and official Secretary of State sources.

Before you file Articles of Organization in Michigan, you need to confirm your LLC name is available and follows state rules. Run your search through the Michigan Department of Licensing and Regulatory Affairs (LARA) at cofs.lara.state.mi.us. The search itself takes about two minutes. But your name isn’t locked in until you either reserve it for $25 or file your formation paperwork. Pick a name that’s already taken and your filing gets rejected, costing you the $50 formation fee and days of waiting.

How to Search Michigan LLC Names: Step-by-Step

Step 1: Open the LARA Business Entity Search

Go to cofs.lara.state.mi.us and click “Business Entity Search” from the menu. This is the official Michigan Corporations Online Filing System (COFS), run by the Department of Licensing and Regulatory Affairs Corporations Division. It’s free, public, and updated in near real time.

You don’t need an account to search. You only need an account if you plan to file or reserve a name through the portal.

Step 2: Enter Your Proposed Name

Type your desired LLC name into the “Entity Name” field. Drop the designator for the first search. If you want “Great Lakes Roofing LLC,” search “Great Lakes Roofing” first. The designator (LLC, L.L.C., etc.) doesn’t make a name distinguishable, so searching without it gives you the real picture.

Set the search type to “Begins With” or “Contains.” “Contains” casts a wider net and surfaces near-matches you’d miss with an exact search.

Step 3: Review the Results

The system returns a list of every Michigan business entity matching your query, along with entity type (LLC, corporation, LP), status (Active, Dissolved, Withdrawn), and identification number. Click any result to see formation date, registered agent, and filing history.

An “Active” entity with your exact name means you can’t use it. A “Dissolved” or “Withdrawn” entity may free the name up, but Michigan doesn’t release dissolved names immediately, and some restrictions can linger. Call LARA at (517) 241-6470 if you want to confirm whether a dissolved name is reusable.

Step 4: Test Variations

If your first choice is taken, run searches for close variants. Michigan’s distinguishability standard is strict: just adding “The,” changing punctuation, swapping “and” for “&,” or pluralizing won’t make your name distinguishable from an existing one. You’ll need a meaningfully different word.

Step 5: Check Beyond the State Database

State availability isn’t the same as legal availability. Run your name through the USPTO trademark database to spot federal trademark conflicts. Then search Google, Instagram, and your preferred domain registrar. A Michigan LLC can technically register a name that conflicts with a federal trademark, but you’ll get sued the moment you start operating.

Step 6: Lock It In

Once you’ve confirmed availability, you have two paths. File Articles of Organization right away ($50) and your name is yours. Or reserve it for $25, which holds the name for six months while you finish your business plan, line up funding, or sort out partner agreements.

Michigan LLC Naming Rules

Designator Requirement

Under Michigan Compiled Laws Section 450.4204, every LLC name must contain one of these designators: “Limited Liability Company,” “L.L.C.,” “LLC,” “L.C.,” or “LC.” Capitalization and periods are flexible. “Limited” can be abbreviated as “Ltd.” and “Company” as “Co.” So “Detroit Auto Repair Ltd. Liability Co.” is valid, even if unusual.

Distinguishability on the Record

Your name has to be distinguishable from every active and reserved name on LARA’s records. That includes domestic and foreign LLCs, corporations, limited partnerships, and assumed names (DBAs).

Michigan considers these differences insufficient:

• Adding or removing “The,” “A,” or “An”
• Changing singular to plural (or vice versa)
• Swapping “and” with “&” or “+”
• Different punctuation, spacing, or capitalization
• Adding or removing the entity designator (LLC vs. Inc.)

You need a different distinctive word. “Great Lakes Marketing LLC” and “Great Lakes Marketing Group LLC” would likely both pass; “Great Lakes Marketing LLC” and “The Great Lakes Marketing, L.L.C.” would not.

Prohibited Words

Some words can’t appear in any Michigan LLC name without specific authority:

• “Corporation,” “Corp.,” “Incorporated,” or “Inc.” (these signal a corporation, not an LLC)
• Words implying the entity is a government agency (FBI, Treasury, State Department)
• “Olympic” or related Olympic terminology (federal restriction)

Restricted Words Requiring Approval

These words require approval from the relevant Michigan regulator before LARA will accept your filing:

• Bank, banker, banking, trust: Michigan Department of Insurance and Financial Services (DIFS)
• Insurance, insurer, surety: DIFS
• Cooperative or co-op: Specific statutory requirements apply
• Attorney, lawyer, law firm: Members must be licensed Michigan attorneys; a PLLC may be required
• Doctor, physician, medical, dental, chiropractic: Licensed professional members; usually requires a PLLC
• Engineer, architect, accountant, CPA: Professional licensing rules apply

If you want a regulated word, plan an extra two to four weeks for the approval letter before you can file.

What If Your Michigan LLC Name Is Already Taken?

Try Strategic Variations

The fastest fix is adding a meaningful word. If “Mitten Coffee LLC” is taken, try:

• Geographic: “Mitten Coffee Detroit LLC” or “West Michigan Mitten Coffee LLC”
• Descriptive: “Mitten Coffee Roasters LLC” or “Mitten Coffee Trading LLC”
• Industry suffix: “Mitten Coffee Group LLC” or “Mitten Coffee Co. LLC”

Run each variation through the LARA search before you fall in love with one.

Reserve the Name for $25

If you’ve found an available name but you’re not ready to file, reserve it. Michigan lets you file Form CD-540 (Application for Reservation of Name) for $25. The reservation holds the name for six months. You can renew it once for another six months at the same fee.

This is useful if you’re still finalizing your operating agreement, opening a business bank account that wants formation documents, or waiting on a co-owner’s signature.

File a DBA (Assumed Name)

Your registered LLC name and your customer-facing brand don’t have to match. If “Mitten Coffee LLC” is taken but you formed “GLC Holdings LLC,” you can file a Certificate of Assumed Name with LARA for $25 and operate publicly as “Mitten Coffee” (or anything else available). The assumed name lasts five years and renews for $25.

This isn’t a workaround for the distinguishability rule, the assumed name itself still has to be distinguishable, but it gives you brand flexibility.

Trademark Considerations

Michigan registration doesn’t grant trademark rights. If you plan to operate beyond Michigan, build a national brand, or sell online, file a federal trademark with the USPTO ($250 to $350 per class). A federal trademark beats a state LLC registration when there’s a conflict, even in Michigan.

After You Confirm Your Michigan LLC Name

Once your name is available, file Articles of Organization (Form CD-700) with LARA. The fee is $50 and standard processing runs 10 to 15 business days, with expedited options at $50 (24-hour), $100 (same-day), $500 (2-hour), or $1,000 (1-hour). You’ll also need a Michigan registered agent and an EIN from the IRS.

Walk through the full process in our Michigan LLC formation guide, compare service options in the Michigan LLC overview, learn the registered agent requirements in our Michigan registered agent guide, and draft your Michigan LLC operating agreement before you open a bank account.

Frequently Asked Questions

How do I know if my Michigan LLC name is actually available?

Search the LARA business entity database at cofs.lara.state.mi.us. If no active or reserved entity matches your name (under Michigan’s distinguishability standard), it’s available. The final check happens when LARA reviews your Articles of Organization, which usually takes 10 to 15 business days under standard processing.

How long does a Michigan name reservation last?

Six months. You file Form CD-540 with a $25 fee, and LARA holds the name for you. You can renew once for another six-month period at the same fee. After that, you either file Articles of Organization or release the name.

Can my LLC name be different from my business brand?

Yes. File a Certificate of Assumed Name with LARA for $25 and operate under any available DBA. Your legal LLC name appears on contracts, tax filings, and bank accounts; your assumed name appears on signage, websites, and marketing. The assumed name registration lasts five years.

Does my domain name need to match my LLC name?

No, but it helps. Customers search for your brand, not your legal entity name. Check domain availability before you finalize the LLC name. If your top choice is taken as a .com, consider adjusting the LLC name slightly or using a DBA that matches an available domain.

What makes two Michigan LLC names “distinguishable”?

A meaningful difference in wording. Adding “The,” changing punctuation, swapping “and” for “&,” or pluralizing isn’t enough. You need a different distinctive word. “Lakeside Marketing LLC” and “Lakeside Digital Marketing LLC” usually pass; “Lakeside Marketing LLC” and “Lakeside Marketings, L.L.C.” won’t.

Can I use a name from a dissolved Michigan LLC?

Sometimes. Dissolved or withdrawn names may become available, but Michigan doesn’t release them immediately, and there can be a waiting period. The safest move is to call LARA at (517) 241-6470 with the entity ID and ask whether the name is clear before you file.

Do I need a different name if I’m forming a professional LLC (PLLC)?

Yes. A Michigan PLLC must include “Professional Limited Liability Company,” “P.L.L.C.,” or “PLLC” in the name (instead of LLC). The same distinguishability and prohibited-word rules apply, plus the licensing board for your profession has to approve the use of regulated terms like “doctor,” “attorney,” or “engineer.”
