South Dakota LLC name lookup

South Dakota Secretary of State Business Name and LLC Search:
Tip: Select “Contains” as your search option when going through the South Dakota name database. This option will display more business names that may be similar to your desired LLC name in the search results.
Statute: South Dakota LLC name rules and restrictions are governed by Section 47-34A-105 of the South Dakota Uniform LLC Act.
How to Search an LLC Name in South Dakota
1. It’s best to search only part of your LLC name to ensure you see everything that is potentially similar. For example, if your desired South Dakota LLC name is “Organic Produce Market LLC”, it’s best to just search “Organic Produce”.
Why: This way, if there is a “Organic Produce Markets” or “Organic Produce Marketing”, you’ll see both of them; which is important, since they will be confusingly similar to your name and the state may reject your LLC filing.
2. Leave out the designator “LLC”, “L.L.C.”, etc., during your search.
3. Leave out any punctuation like commas, periods, apostrophes, quotes, hyphens, etc.
4. The South Dakota name database ignores capitalization so you can search using uppercase letters, lowercase, or any combination.
5. Use “Contains” (instead of “Starts With”) to broaden your search criteria so you can see all the names that are potentially similar to yours.

How to Determine the Search Results:
• If the results show names that are not too similar to yours, then your desired South Dakota LLC name is available for use.
• If a “No Records Found” message appears, this means your desired South Dakota LLC name is unique and available for use.
• If your desired LLC name already appears in the list exactly as you want it, your desired South Dakota LLC name is not available for use. You’ll need to come up with a new name or unique variation that makes your LLC name distinguishable.
• If the results show a name that is deceptively similar to yours, your desired South Dakota LLC name will likely be rejected. We recommend coming up with a new name or unique variation that makes your LLC distinguishable.
Statuses in the Secretary of State’s Database
You’ll see different statuses when going through the businesses in the Secretary of State’s database.
If you see the following statutes to the right of a name that you would like, this name will not be available for use:
• Good Standing
If you see the following statutes to the right of a name that you would like, this name will be available for use:
• Revoked (Administrative)
However, there is a chance the prior owners of those names can make a claim against your business. Additionally, courts, collection agencies, or similar places may mistake your new company for someone’s old company. In order to avoid any future headaches, lawsuits, or claims, we recommend choosing a South Dakota LLC name that is truly unique instead of using someone’s old name.
South Dakota LLC Name Requirements & Restrictions
Before finalizing your LLC name, it’s important to understand the requirements and restrictions in South Dakota.
Here is a brief overview (scroll down for details on each bullet point):
• LLC designators: You must use a proper designator at the end of your LLC name
• Restricted designators: You cannot make it sound like your LLC is a Corporation

Your South Dakota LLC must contain one of the following designators at the end of its name:
• LLC (most popular)

• Limited Liability Company
Example: If your desired name is “Gem’s Haberdashery Services”, it must be officially filed as “Gem’s Haberdashery Services LLC”, “Gem’s Haberdashery Services L.L.C.”, etc.
Tip: If you’re not sure which designator to use, “LLC” is the most common.
Your South Dakota LLC cannot imply that it is a Corporation, Limited Partnership, or any other type of business entity besides an LLC.
You cannot use the following Designators anywhere in your LLC name:

Comma in LLC Name
You can file your LLC name with or without a comma before the designator. Both are acceptable in South Dakota.
For example, you can file as either “John’s Party Store, LLC” or “John’s Party Store LLC”. It’s up to your personal preference.
