The primary duty of a Delaware registered agent is to maintain a physical location in Delaware (known as a registered office) where the agent can receive and accept service of process and official mail during all normal business hours. This is essentially the statutory requirement for a Delaware registered agent.

A lesser known requirement is that all Delaware registered agents are required to maintain an updated communications contact for each entity the agent represents. The communications contact must be a person designated by the LLC or corporation to receive communication from the registered agent. The LLC or corporation must provide to the registered agent its communication contact’s business address and business telephone number. If the entity does not keep this information updated, the registered agent may resign. On the registered agent’s end, they must keep track of this vital information for each entity so that service of process and official mail can be delivered properly.
