A registered agent receives legal papers for the company. That role has its own rules, separate from the address lines above. Delaware's statute says:
“A registered agent may not perform its duties or functions solely through the use of a virtual office, the retention by the agent of a mail forwarding service, or both.”
The same paragraph defines "virtual office" as performing duties or functions solely through the internet or solely through other means of remote communication.
Wyoming and Texas also describe the registered office as a street address where someone can be served in person. Their rows are in the tables above. save office provides business and mailing addresses and does not sell registered agent service.
