Naming the LLC

Naming Guidelines in South Dakota

In South Dakota, an LLC must publicly showcase its status by including one of the following phrases as part of the official company name: “LLC,” “L.L.C.,” or “Limited Liability Corporation.” If there are any restricted words in the name of the company, additional paperwork will be required. If a word is already being used by a federal or a state agency, that word is fully prohibited, not just restricted, in South Dakota.

Is the Domain Name Available?

Companies should check with a domain name registrar to see if a domain name is available. It is not a formal requirement to format a domain name in a certain way; no iteration of “LLC” in the URL is necessary in order to remain in compliance.

Select a Registered/Statutory Agent


South Dakota wants to be able to get in touch with businesses in its jurisdiction. Having a P. O. Box as a business address is not good enough for the state. The state also wants to keep up with incorporated business entities for tax purposes and separate them from independent contractors and self employed individuals. The registered agent helps the state accomplish these goals.

The registered agent is a person or a company that will receive any service of process correspondence [read: official mail] if a business is involved in any legal action. Registered agents also serve as a permanent address for the state of South Dakota to send paperwork to a company.

A registered agent may also be known as a ‘resident agent’ or a ‘statutory agent.’

Who Can be a Registered Agent in South Dakota?

In South Dakota, companies may have a company employee or an outside individual or company serve as the registered agent. However, if the agent is a corporation, it must be duly authorized to operate in the state. If the registered agent is an individual, that person must be a resident of South Dakota.
