1. Use the South Dakota Business Name Search

The South Dakota Secretary of State Office offers different search options:

a. Name Search

To begin, the most common method is the Name Search. This tool, available on the South Dakota Secretary of State's website, allows you to search for a business by its registered name.

Here's how you can search for business name availability:

• Go to the Business Name Availability Search on the South Dakota Secretary of State website.
• In the provided field, type the business name you wish to check for availability.
• Click on the 'Search' button to initiate the search process.
• The search will return results indicating whether the name is available or already in use.
• If the name is available, you may proceed with the registration process.
• If the name is in use, consider alternative names or slight variations.

"If the search results reveal names that are sufficiently distinct from yours, indicating that your Limited Liability Company name is unique, then it is available for use."

b. State Business ID Number

Each LLC in South Dakota is assigned a unique ID Number upon registration.

Searching by this number is particularly useful if you have specific details about the LLC.

Here is how you can go about the search:

• Visit the Business Information Search page on the South Dakota Secretary of State website.
• On the search page, you will find different search options. Choose the 'ID Search' tab to search by the State Business ID.
• In the provided field, type the specific State Business ID of the LLC you seek.
• Click on the 'Search' button to start the search process.
• The search will return information about the LLC associated with the entered State Business ID.

2. Call the State

For personalized assistance or specific queries, contacting the South Dakota Secretary of State's office is a reliable option. Reach out at (605) 773-4845 for direct support from state officials.

This method is particularly useful for complex questions or when seeking guidance on legal compliance and registration processes.

3. Send an Email

Alternatively, you can send an email to the Secretary of State's office at sos@state.sd.us. This channel is ideal for non-urgent inquiries and when you need a written record of the information provided.

4. Other Business Entity Search Alternatives

There are also other unofficial avenues to get information about an LLC in South Dakota.

They serve different purposes than official state business entity searches and may provide varying levels of detail and reliability.

Here's a brief overview of each:

a. Social Media Platforms

Many businesses have a social media presence. Platforms like LinkedIn can be particularly informative.

b. Search Engines

A simple Google search can sometimes reveal information about an LLC, including news articles and website links.

c. Industry-Specific Databases

Depending on the business sector, databases may list registered businesses.

d. Local Business Directories

How to Check If A Business Name Is Trademarked in South Dakota?

To check if a business name is trademarked in South Dakota, conduct a search on the South Dakota Secretary of State's website and the United States Patent and Trademark Office (USPTO) database for federal trademarks.

According to recent statistics, approximately 77% of trademark applications are approved by the USPTO, with the process taking an average of 8-12 months for completion, as reported by the USPTO's official data.

1. United States Patent and Trademark Office (USPTO) database

To check if a business name is trademarked, the primary resource is the United States Patent and Trademark Office (USPTO) database.

Here's how you can conduct this search:

• Start by visiting the USPTO's official website.
• Access the Trademark Electronic Search System (TESS).
• Input the business name you're considering.
• Click search, and the system will display any existing trademarks or applications identical or similar to your proposed name.
• Review the results carefully. If there's a match or a close similarity, it's a strong indicator that you should consider a different name to avoid potential legal issues.

2. Using the Secretary of State's Website for State-Level Trademark Search

In South Dakota, the Secretary of State's office maintains a registry of trademarks that are registered within the state.

This is crucial because a business might have a trademark registered at the state level, which wouldn't necessarily appear in the USPTO database.

To search the Secretary of State's website:

• Visit the South Dakota Secretary of State's Website.
• Navigate to the Trademark Search Tool.
• Use the search tool to enter the name you are considering for your LLC.
• The system will display any state-registered trademarks that match or closely resemble your proposed name.
• Like the USPTO search, you must review the results for exact matches or close similarities.
• Pay attention to trademarks in the same or related industries as your intended business.

State-level trademarks protect the name within the state of South Dakota. A federal trademark might be more appropriate if your business plans to operate nationally or you want broader protection.

According to the South Dakota Secretary of State website, as of January 2024, approximately 80% of businesses in South Dakota opt for state-level trademarks, while the remaining 20% choose federal trademarks.
