Michigan Business Name Search: How to Check and Reserve a Name

Choosing and securing a business name is one of the first steps in forming a Michigan company. But before you file your formation documents with the Michigan Department of Licensing and Regulatory Affairs (LARA), you need to verify that your chosen name is actually available. A name search protects you from legal conflicts and wasted filing fees on a name you cannot use.

This guide walks you through searching for an available Michigan business name, understanding the state's naming rules, and how to reserve your name if you want to lock it in before filing incorporation or LLC formation documents.

Before You Start: What You'll Need

The Michigan business name search is free and requires very little upfront preparation:

• A web browser and internet connection
• Your proposed business name (have 2 to 3 alternatives ready, in case your first choice is taken)
• A basic understanding of your business structure (sole proprietorship, LLC, corporation, etc.)
• A way to pay the $25 fee, if you decide to reserve an LLC name (check or money order if you file by mail)

The entire search process takes fewer than 5 minutes, and you can repeat it as many times as you want with different name variations at no cost.

Step 1: Navigate to the Michigan Business Registry

Start your search on the official Michigan business registry operated by LARA, the Department of Licensing and Regulatory Affairs. This is the authoritative source for all registered Michigan business entities.

Go to https://mibusinessregistry.lara.state.mi.us/search/business. This is a public database that shows every active business entity registered with the state. You'll also find here any names that other businesses have reserved but not yet formed.

The search portal is called the MiBusiness Registry Portal (MiBRP). Bookmark this page if you plan to run multiple searches or return to check on your reservation status later.

Step 2: Enter Your Proposed Business Name

On the search page, you'll see a text field labeled "Business Name." Type your proposed business name exactly as you plan to file it. The search is not case-sensitive, so "ABC SERVICES" and "abc services" return the same results.

Do not include abbreviations like "Inc." or "LLC" in the search field itself, even if you plan to include them in your legal name. Search first for the core name (for example, search for "Riverside Consulting" rather than "Riverside Consulting LLC"). You'll verify the full legal naming rules in the next section.

If your name is longer than a few words, try searching for variations. For instance, if your proposed name is "Michigan Premium Landscaping Services," try searching for just "Michigan Premium Landscaping" or even "Premium Landscaping" to catch any similar existing names. LARA's search function looks for exact or very similar matches.

Step 3: Review the Search Results

Hit "Search" and review the results page. The database will show you:

• Any active business entities with the exact name or a confusingly similar name
• Reserved names (names held by others who have not yet filed formation documents)
• Inactive or dissolved businesses with that name (these are generally available for reuse, though LARA may request distinguishing language)

A blank result screen is a good sign, but only LARA's review of your filing confirms the name is available. Even if no exact match appears, you still need to verify that your name meets Michigan's naming requirements for your entity type. An available name that violates naming rules will be rejected when you file.

If your search returns a result that concerns you, look closely at the status. An "Active" entity with your exact name means the name is taken. A "Reserved" name means someone else has filed a reservation but not yet incorporated or formed the LLC. A name listed as "Dissolved" or "Inactive" is generally available, but LARA may ask you to add distinguishing language (like a number or geographic identifier) to your name when you file.

Step 4: Check the Naming Requirements for Your Entity Type

Michigan's naming rules vary by the type of business entity you are forming. An available name is only truly available if it also complies with the state's requirements for your business structure.

Limited Liability Companies (LLCs)

If you are forming an LLC, your business name must include one of the following:

• The words "Limited Liability Company"
• The abbreviation "L.L.C." or "LLC" (with or without periods)
• The abbreviation "L.C." (with or without periods)

Your LLC name also cannot contain "corporation" or "incorporated" or the abbreviations "corp." or "inc.", cannot indicate or imply a purpose other than the one in your articles, and cannot contain a word that another Michigan statute prohibits or restricts (MCL 450.4204(3)). Words tied to regulated industries, such as bank or insurance, are the kind to check before you file.

Professional LLCs (for doctors, lawyers, accountants, and other licensed professionals) have additional rules. The name must contain the words "Professional Limited Liability Company" or the abbreviation "P.L.L.C.", "P.L.C.", "PLLC" or "PLC" (Form CSCL/CD-701 instructions).

Corporations

If you are incorporating as a Michigan for-profit corporation, your business name must contain one of the following (it need not come at the end):

• "Corporation"
• "Incorporated" or "Inc."
• "Company" or "Co."
• "Limited" or "Ltd."

Like LLCs, corporations cannot use a name that implies a purpose outside their articles or a word that another Michigan statute restricts (MCL 450.1212).

Sole Proprietorships and Partnerships

Sole proprietorships and general partnerships that do business under a name other than the owner's legal name must file an assumed name certificate with the clerk of each county where they do business (MCL 445.1). LARA's Certificate of Assumed Name (Form CSCL/CD-541) is for LLCs, corporations and limited partnerships. These entities do not have formal "naming" requirements in the same way that LLCs and corporations do. However, an assumed name that is too close to an existing business name can cause problems, so run the same MiBRP search as a first check.

Step 5: Decide Whether to Reserve Your Name

If your search shows that your name is available and complies with Michigan's rules, you have two options:

Option 1: File Your Formation Documents Now

If you are ready to officially form your business, you can proceed directly to filing your Articles of Organization (for an LLC) or Articles of Incorporation (for a corporation) with LARA. Once your formation documents are filed and accepted, your business name is legally protected and registered. This is the fastest path if you are ready to move forward immediately.

Option 2: Reserve Your Name for Later

If you want to lock in your name before you file formation documents, you can file a Name Reservation with LARA. This protects your name for six months following the month of filing, giving you time to finalize your business plan, apply for licenses, or arrange financing without worrying that someone else will claim your name.

Step 6: File a Name Reservation (Optional)

To reserve a business name in Michigan, file Form CSCL/CD-540 (Application for Reservation of Name) with LARA's Corporations Division. The form's instructions say it can be completed and submitted online (www.michigan.gov/corpfileonline).

Cost: $25 for an LLC name. The fee schedule lists $10 for a corporation name.

Duration: Six months following the month of filing. The reservation does not renew on its own, but the Form 540 instructions say that for corporations and LLCs the name may be reserved again after it expires by filing another application and fee. Forming the entity before the reservation expires is how you keep the name.

Who Can Reserve: Any person or organization can reserve a name, whether or not they are a Michigan resident or citizen. You do not have to form the entity in Michigan for someone else to reserve the name, any person anywhere in the US can file a Michigan name reservation.

How to File: Submit Form CSCL/CD-540 online (the form's instructions point to www.michigan.gov/corpfileonline), or mail it with a check or money order to LARA's Corporations Division, P.O. Box 30054, Lansing, MI 48909. You can also use the MiBusiness Registry Portal to search for the name first.

LARA does not publish a guaranteed standard processing time for routine filings.

Common Mistakes to Avoid

Forgetting to Include the LLC or Corporate Designator

Many first-time business owners search for and find an available name like "Riverside Consulting" but then forget to add "LLC" or "Inc." when filing. The name will be rejected by LARA. Your search should include the full legal name you plan to file, including the required designator for your entity type.

Assuming a Similar Name Is Available Because Yours Is

If your search shows that "Riverside Consulting LLC" is available, that does not automatically mean "Riverside Consulting Services LLC" is also available. Search for each variation you are considering. LARA evaluates confusing similarity on a case-by-case basis, and two names that sound alike may both be rejected, or only one might be.

Not Searching Variations of Your Name

Before you settle on a name, search for common misspellings and variations. If "Riverside" could be spelled "Riverside" or "River Side," search both. This is especially important if your name includes a less common word. A competitor could register a variation and create customer confusion, even if your exact name is protected.

Reserving a Name and Then Forgetting to File Formation Documents

A name reservation lasts six months. If you file the reservation and then do not form the LLC or corporation before the six-month period ends, your name becomes available to anyone else. Mark the expiration date on your calendar and plan to file your formation documents before that date if you want to keep the name.

What to Do If Your Name Is Taken

If your search reveals that your preferred name is already registered or reserved, you have several options:

Contact the Owner: If the name belongs to an active business, you can sometimes negotiate with the owner to purchase the name or use a very similar alternative. The MiBRP search shows basic company information; you may be able to find contact details from their website.

Add Distinguishing Language: LARA allows you to register a name that is similar to an existing name if you add distinguishing language (such as a location, a number, or a descriptor) that makes it clear your business is different. For example, if "Riverside Consulting LLC" is taken, you might file as "Riverside Consulting Detroit LLC" or "Riverside Consulting 2.0 LLC." This is not automatic approval, but it is a common solution.

Choose a Different Name: This is often the simplest path. Use the brainstorm names you prepared before you started the search. Run the same steps to check availability and naming compliance on your second and third choices.

After Your Name Is Reserved or Filed

Once LARA accepts your name reservation or your formation documents are filed and accepted, your name is protected in Michigan. However, this does NOT protect your business name at the federal level or in other states.

If your business operates across state lines or online, you should consider:

• Registering your name as a trademark with the US Patent and Trademark Office if the name is truly unique to your brand
• Filing a DBA (Doing Business As) or fictitious name registration in any other state where you conduct substantial business
• Registering matching domain names and social media accounts to prevent others from claiming them

These steps are beyond LARA's scope but are important for protecting your business identity long-term.

Key Takeaways

Searching for an available Michigan business name is quick, free, and essential before you file any formation documents. Use the official MiBRP business search, verify that your name complies with Michigan's naming requirements for your entity type, and consider filing a $25 name reservation if you want to lock in your choice before filing formation documents.

Once your name is secured, you can move forward with the rest of your business formation process with confidence.
