The Secretary of State (SOS) is a government agency that is an official body responsible for operating in 47 of the 50 US states. In some states, the local Secretary of State’s office is called the Department of State. The SOS department manages the state’s business entities, including corporations, professional corporations, LLCs, and others. The Secretary of State’s office also oversees business registrations within its jurisdiction, which is essential for legally operating in a state.
So, when a US-based company operates in a certain state, it is required to register with the Secretary of State. This includes filing information and registering documents with the Secretary of State filing. Their responsibilities also include maintaining an online database, which can be accessed for information like registered agent details and other documents, such as Articles of Incorporation.
