Check LLC Name Availability in South Dakota

1. Do a South Dakota Business Name Search

You can use South Dakota’s Business Name Availability Search for an EXACT name search and the Business Information Search for variations of a name to check the availability of your desired name.

To perform the most effective search, type in the name you would like to use, excluding identifiers like “LLC.” This will return all entities using the same or similar names. If your business name is several words, you can even search just the first two words to ensure you pull up all possible similar names.

Be sure to conduct a thorough search before completing your paperwork to avoid rejection. 

2. Search Available Domain Names

Another important consideration to make when selecting a business name is whether or not your desired web domain name is available.

Having a URL that clearly matches your business name is important. This seemingly small step can make a big difference in how prospective customers find your business.

The best way to determine if your desired URL is available is to search for it online using your preferred domain registry, such as GoDaddy.

3. Follow South Dakota Naming Guidelines

When choosing a name for your limited liability company (LLC) in South Dakota, there are specific guidelines you need to follow.

Required Designators

Your LLC name must include one of the following designators:

• "Limited Liability Company"
• "Limited Company"
• Abbreviations: "L.L.C.," "LLC," "L.C.," or "LC"
• "Limited" may be abbreviated as "Ltd."
• "Company" may be abbreviated as "Co."

Examples of acceptable names include:

• ABC Consulting Limited Liability Company
• XYZ Holdings LLC

Distinguishability From Other Entities

To register your LLC name in South Dakota, it must be distinguishable from the following:

• Names of existing corporations, limited partnerships, or companies incorporated, organized, or authorized to do business in the state.
• Names reserved or registered with the state.
• Fictitious names approved for foreign companies authorized to do business in South Dakota due to the unavailability of their real name.

Authorization for Non-Distinguishable Names

In some cases, you may apply to the Secretary of State for authorization to use a name that is not distinguishable from existing names. Authorization can be granted if:

• The current user, registrant, or owner of a reserved name consents to your use of the name and undertakes to change their name to a distinguishable one.
• You provide a certified copy of a final judgment from a court of competent jurisdiction, establishing your right to use the name in South Dakota.

Use of Another Company's Name

Your LLC may use the name of another domestic or foreign company if the other company is organized or authorized to do business in South Dakota and:

• You have merged with the other company.
• You have been formed by reorganization with the other company.
• You have acquired substantially all of the assets, including the name, of the other company.

Reserve Your South Dakota Business Entity Name

To reserve a business name, you must file an application by mail. There is currently no online option for name reservations. When reserving your name, you will have to pay a filing fee. Checks must be made out to the “Secretary of State.”

Other Considerations

While reserving the name for your LLC is straightforward, there are some other things you should think about when choosing the best name for your business. You may want to do a Trademark and Social Media search for your name to see if it's available for use across the internet. This will help ensure you have full, unrestricted use of your business name.

Trademark Search

Conducting a trademark search of your business name and associated slogans or logos before registering can help prevent costly litigation in the future. Discovering that another entity has trademarked your business name does not automatically disqualify you from using it.

However, it is important to know who is using the name, what industry they operate in, and where they are located to be sure you do not inadvertently infringe upon anyone’s intellectual property rights.

To complete this step: 

• Search South Dakota’s trademark records by filling out the Trademark Database Subscription form to see if your business name or associated slogans, logos, or others are in use by another business in your state. 
• Search the U.S. Patent and Trademark Office’s electronic records to find any federally registered trademarks associated with your business name.

Social Media Search

Just as important, or more so, than finding a domain name that fits your business is ensuring that your business name is available for use across social media platforms. You can do this by simply searching your business name on each major site, or use a tool such as Namecheckr to search across all platforms at once.

Bottom Line

Having a name for your business is an important first step for creating a successful LLC, and one that is incredibly easy to do. Once you have found your preferred name using South Dakota's Business Information Search and Name Availability Search, you'll want to secure your domain name so that your customers will be able to find your business online. Reserving your name with an Application for Reservation of Name will help you stand out from the competition. With your name secured, you will be ready to take the next steps to formalize your LLC.
