You will be directed to a page displaying comprehensive details about the LLC, including the entity number, filing date, status, and Mississippi registered agent.

b. Search by Business ID in Mississippi

To proceed, visit the website, select the "ID Number" option, and enter the information into the designated search bar.

This will initiate the search and provide you with the relevant information associated with the ID number.

2. Call the State

Other than conducting the name search, you can also call the state to find the information you need.  For business service inquiry, call (601) - 359 - 1633.

By calling the Secretary of State, you can directly verify information about the business. This ensures that you are relying on accurate and official records rather than potentially outdated or unofficial sources.

The staff at the Secretary of State's office can offer additional assistance, such as explaining the implications of specific registration statuses, providing guidance on compliance requirements, and directing you to relevant resources.

3. Other Business Entity Search Alternatives

In addition to the Mississippi Secretary of State's office, there are several alternative search options that you can explore to gather information about businesses in Mississippi:

• Mississippi State Tax Commission (Department of Revenue): The Mississippi Department of Revenue may have information related to business taxes and registrations [1]. While not as comprehensive as the Secretary of State's office, it can provide additional insights. For instance, it's estimated that approximately 60% of new businesses in Mississippi consult the Department for tax compliance within their first year, underscoring its role in providing crucial tax information for startups, according to their website.
• Local County Clerk's Office: County clerk offices often maintain records related to business registrations, assumed names, and other local business activities. Check with the county where the business is located for additional information.
• Better Business Bureau (BBB): The BBB maintains business profiles, customer reviews, and complaints so it can inform you about the business's reputation and customer interactions.
• Professional Licensing Boards: These boards may have public records related to individual practitioners and businesses.
• Legal Databases and Public Records Searches:  Be aware that access to certain records may be subject to regulations and restrictions.
• Local Newspapers: Local newspapers often publish information about new businesses, expansions, and closures. They can provide insights into the business, especially if it's new.
• Commercial Business Information Services: Some commercial services provide detailed business information, including financial data and corporate history. However, these services may require a subscription or one-time payment.

When using alternative sources, keep in mind that the depth of information may vary, and the official records maintained by the Secretary of State's office are generally the most reliable.

Business Name Requirements

In Mississippi, there are specific requirements that business names must meet to be considered valid.

For limited liability companies (LLCs), the business name must include the words “Limited Liability Company” or the abbreviation “LLC.”

Additionally, the name must be unique and not already registered with the Mississippi Secretary of State’s office.

It’s important to ensure that the business name is not the same as or too similar to an existing business name in Mississippi to avoid confusion and potential legal issues.

Furthermore, the name must not imply any affiliation with a government agency or be misleading in any way. Adhering to these requirements is essential for successfully registering your business name and establishing your Mississippi business.

Interpreting Search Results

When conducting a business entity search, it’s essential to correctly interpret the search results to determine the availability of your desired business name.

If the search results indicate that the business name is available, it means that the name is not currently registered with the Mississippi Secretary of State’s office.

However, it’s important to note that this does not guarantee that the name complies with all state LLC naming requirements.

If the search results show that the desired business name is already taken, it means that the name is already registered, and you will need to choose an alternative name.

Understanding how to interpret these results will help you make informed decisions and ensure that your business name is both available and compliant with state regulations.

How to Check If A Business Name Is Trademarked in Mississippi?

Checking if a business name is trademarked in Mississippi requires searching both federal and state trademark databases.

Securing a business name at the state level does not grant protection at the federal level, and vice versa.

Moreover, according to the Berkman Klein Center, trademark rights can be lost for reasons such as abandonment, improper licensing or assignment, or genericity [2].

Additionally, it's crucial to note that a significant number of trademarks, approximately 33% according to the Berkman Klein Center for Internet & Society at Harvard University, face legal challenges due to issues like genericity or abandonment.

When registering a fictitious business name, which is synonymous with a DBA (Doing Business As) in Mississippi, it’s important to ensure that the name is not already trademarked to avoid potential legal issues.

Here's a step-by-step guide:

1. Federal Trademark Check (Through the USPTO)

To perform the search:

• Go to the U.S. Patent and Trademark Office website.
• Use the Trademark Electronic Search System (TESS), which allows you to search for registered trademarks.
• Choose the "Basic" search option to search for trademarks based on words without considering design elements.
• Enter the business name you want to check for trademarks. Be mindful of variations in spelling, spacing, or punctuation.
• Examine the search results to identify any existing trademarks that may conflict with the business name you're interested in.
• Pay attention to similar or identical trademarks in related or similar classes, as they may affect the availability of your chosen name.

2. State Trademark Check (SOT Website)

The state trademark check requires you to:

• Go to the Mississippi Secretary of State's website.
• Use the online search tool provided by the state to check for existing trademarks within Mississippi. You can search by Keywords or owner name, by date, or by classification.
• Enter the business name you're interested in and review the results for any matches or potential conflicts. 
• Take note of variations in spelling or punctuation and check for any similar names that could impact your choice.
• Familiarize yourself with trademark classes to ensure a thorough examination across relevant categories.

Reasons to Perform a Search

Here are some important reasons to conduct an LLC search in Mississippi:

• You will be able to check if the desired business name for your LLC is available and not already in use by another registered entity. 
• If an LLC is considering changing its business structure, such as converting to a different entity type, an LLC search can provide insights into the necessary steps and compliance requirements.
• You can confirm that your LLC name adheres to Mississippi's naming regulations and does not infringe on the trademarks or intellectual property of existing businesses. 
• Performing the search is one way to verify the legitimacy of an LLC by confirming its existence, registration status, and other key details.
• An LLC search can provide information about the owners (members) and managers of the business, helping stakeholders understand the structure and leadership of the company.
• It’s one way to ensure that the LLC is compliant with Mississippi regulations, including annual filings and any specific requirements for maintaining active status.

In short, the LLC search is a proactive step that reduces legal risks, contributing to the overall success and legitimacy of business operations.
