South Dakota Secretary of State Business Name and LLC Search:

Business Information 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:

  • Active
  • Good Standing
  • Delinquent

If you see the following statutes to the right of a name that you would like, this name will be available for use:

  • Dissolved
  • Cancelled
  • Terminated
  • Withdrawn
  • 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.
