Verify Your Business Name With a Missouri Business Name Search

Most states offer one way to search their business databases. Missouri offers four options: by business name, by registered agent, by name availability, or by charter number.

You can search for a company by what you have, whether it's the company’s name or a registered agent. This guide walks through all four search types, what your results actually mean, and how to reserve or register a name once you've confirmed it's clear.

Key Takeaways

Missouri's Business Entity Search lets you search by Business Name, Registered Agent, Name Availability, or Charter Number, all from the same page.

The Registered Agent search works in reverse, showing every entity a specific agent represents, useful for vetting a registered agent service before you sign up with them.

A name attached to a dissolved or forfeited entity isn't automatically available for reuse. Confirm through a Name Availability search first.

Name reservations run 60 days and can be renewed twice, for up to 180 days total.

What Is the Missouri Business Entity Search

The Missouri business entity search is a free, no-login database run by the Secretary of State. It lists every corporation, LLC, limited partnership, limited liability partnership, and professional entity registered in the state, each with its name, charter number, status, formation date, registered agent, and filing history. [1]

The Four Search Types, and Which One You Need

• Business Name: The default choice when you know or can guess the company's name.
• Registered Agent: Searches by the agent's name instead, returning every entity that agent represents. Useful for due diligence on a person or firm.
• Name Availability: Checks whether a name you want for a new business is likely free to use.
• Charter Number: An exact-match lookup when you already have the entity's unique ID from a filing, contract, or prior search.

Sole proprietorships and general partnerships do not file formation documents as Missouri business entities. However, if they operate under a registered fictitious name, that fictitious-name registration may appear in the Secretary of State’s records.

How to Search for a Business Entity in Missouri

Step 1. Go to the Official Portal

Open the Secretary of State's Business Entity Search. [1] No account or login is required, and the tool is available 24 hours a day.

Step 2. Choose Your Search Type

Use the first dropdown to pick Business Name, Registered Agent, Name Availability, or Charter Number, depending on what you are trying to find.

Step 3. Enter Your Search Term and Match Type

Type the name, agent, or number into the search box. Then use the second dropdown to choose how the search matches it: Starting With, All Words, Any Word, or Exact Match.

Note: Missouri’s search can be sensitive to spacing and punctuation. Start with the shortest distinctive part of the business name. Use Exact Match only when you know the complete legal name, including its entity designator and punctuation.

Step 4. Check "Active Entities Only" If You Want Current Businesses Only

Mark this checkbox to hide dissolved, forfeited, or cancelled entities from your results. Leave it unchecked if you want to see an entity's full history, including businesses that are no longer active.

Step 5. Click Search and Review Your Results

Results appear in a table showing Business Name, Charter Number, Type, Status, Created date, and Registered Agent Name. Recently submitted filings may not appear immediately. If you expect a record but cannot find it, check the spelling and punctuation, search using less information, or try again later.

Step 6. Open the Full Entity Record

Click any business name to open its General Information page, including the principal office address, registered agent, and tabs for Filings, Principal Office Address, and Contacts.

How to Read Your Business Entity Search Results

What Information Is Public

• Legal entity name and charter number
• Entity type and current status
• Formation date and where the entity was formed (domestic vs. foreign)
• Registered agent name and address
• Principal office address, current and (optionally) historical
• Filing history, with free document views for most filings

What the search generally does not show:

• Beneficial owners or a complete ownership structure
• Shareholder identities or stock holdings
• Every member of a Missouri LLC
• Financial information such as revenue, assets, or bank-account details
• Federal Employer Identification Numbers
• Tax returns or detailed tax-compliance records

What Does Entity Status Mean

Dissolved, forfeited, and cancelled entities stay in the search results with that status shown, so their filing history remains publicly accessible even after they stop operating. A name attached to one of these is not automatically available for reuse; confirm through a Name Availability search before relying on it.

How to Use the Search to Vet a Business

If you are running the search to check out a company before you deal with it, a few patterns are worth a closer look:

• A status of Forfeited, Administratively Dissolved, or Cancelled on a business presenting itself as fully operational.
• A very recent formation date on a company that claims a long track record.
• Several unrelated entities sharing one registered agent and address, which is often an ordinary registered-agent arrangement but occasionally warrants a closer look.
• Missing, outdated, or inconsistent registered-agent information, which may indicate that the business record needs closer review.

Checking Name Availability and Reserving Your Name

If you have a name in mind and are not ready to file yet, Missouri lets you hold that name for up to 180 days through a formal reservation. This step is optional. Many people forming a business skip it and file Articles of Organization directly, since a reservation adds a fee without adding protection once you're ready to file anyway.

A reservation makes sense if you still need time to line up a registered agent, finish an operating agreement, or wait on funding before you file, and want to make sure no one else takes the name in the meantime.

How to Check Business Name Availability

Run the Name Availability search type with your proposed name. No exact match in the results is a good sign, but it is not a guarantee: Missouri requires names to be distinguishable, not merely non-identical, so a close variant can still be rejected when you actually file. If you are still weighing options, our free business name generator can help you find alternatives before you search.

How to Reserve a Name in Missouri

Option A: Online, Through the Secretary of State's portal

1. Create an account or sign in at the Secretary of State's website.
2. Select "Create a Business Entity," then choose "Name Reservation" from the dropdown.
3. Follow the on-screen instructions and pay the applicable state fee. A name reservation costs $25 for most entity types and $30 for a limited liability partnership.

Option B: By Mail

1. Download and complete the Application for Reservation of Name form. [3]
2. Mail it with a $25 ($30 for LLP)check to: Secretary of State, Corporations Division, P.O. Box 778, Jefferson City, MO 65102.
3. Mailed applications are processed in the order received, so processing times may vary.

What a Name Reservation Does and Does Not Protect

• Holds the name for 60 days and can be renewed twice, for a maximum of 180 days.
• Does not itself form your business. You still need to file Articles of Organization or Incorporation before the reservation expires.
• Does not protect against a federal trademark conflict.

Note: After the same applicant has reserved the name for the full 180 days, that applicant cannot reserve it again, although the applicant may still use the name in a formation filing if it remains available.

Missouri Business Naming Conventions

Before you search or reserve a name, it helps to know what Missouri actually allows. A name can appear as available in the search tool and still be rejected at filing if it violates one of the state's naming rules.

Missouri LLC naming rules

• A Missouri LLC name must contain “limited liability company,” “Limited Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.”
• It may not contain “Corporation,” “Incorporated,” “Limited Partnership,” “Limited Liability Partnership,” “Limited Liability Limited Partnership,” “Ltd.,” or an abbreviation of one of those terms.
• The name must be distinguishable from protected business names in the Secretary of State’s records unless the applicant obtains the required consent or establishes a prior legal right to the name.

Missouri corporation naming rules

• A Missouri corporation’s name must contain “Corporation,” “Company,” “Incorporated,” or “Limited,” or end with an abbreviation of one of those words.
• The name may not imply that the corporation is a government agency or is organized for a purpose not permitted under Missouri corporate law.
• It must also be distinguishable from other protected entity names and reserved names in the Secretary of State’s records.

Note: A Name Availability search is only a preliminary check. A name that appears available may still be rejected when the Secretary of State reviews the actual reservation or formation filing.[2]

Fictitious Name (DBA) Search in Missouri

If a person or business operates in Missouri under a name different from its true or registered legal name, it generally must register that name as a fictitious name with the Missouri Secretary of State. The registration must generally be filed within five days after beginning business under the fictitious name.

A fictitious-name registration costs $7 and remains effective for five years. It may be renewed during the six months before its expiration date. Once a registration expires, it cannot be renewed; the business must submit a new registration and will receive a new charter number.

Registering a fictitious name does not reserve the name or provide exclusive ownership rights. More than one person or business may register and use the same fictitious name.[4]

You can register online through Missouri’s Business Filing System or submit the official form by mail or in person. The registration must provide the business name and address, the owners’ names, and their ownership percentages.[5]

What is the Cost to Search and Reserve a Business Name in Missouri

The search itself is free. These are the costs that come up once you act on what you find, whether that is reserving a name, filing a new business, or ordering proof of a company's standing.
