How to Search Available LLC Names in South Dakota

1. Check South Dakota LLC Naming Guidelines

Before you do a name availability search, it makes sense to check if your business name meets the basic state guidelines.

Some key guidelines for South Dakota LLC names include:

  • Your name must include the phrase “limited liability company” or “limited company” or one of their abbreviations (LLC, L.L.C., LC, or L.C.). “Limited” may be abbreviated as “Ltd.,” and “company” may be abbreviated as “Co.”

  • Your name must be distinguishable from any existing business in the state. This includes South Dakota reserved names.

Keep an eye out for restricted words. These words, such as “FBI” or “Treasury,” are often restricted to keep your LLC from sounding like an official institution.

For more information, check out South Dakota's official state statutes.
