All businesses operating in a state as limited partnerships, registered limited liability partnerships, limited liability companies, corporations, professional corporations, nonprofit corporations, and professional associations must register with the Secretary of State.
Corporations, limited partnerships, and limited liability companies organized in other states or countries may transact business in a state by obtaining a certificate of authority through the Secretary of State. The Secretary of State can provide forms for the certificate of authority. An out-of-state business may also consider the option of creating an in state corporation, limited partnership, or limited liability company for transaction of business in that state
A name may not be used by more than one corporation in the state. The Secretary of State will perform a name search to verify that no other corporation, limited partnership, or limited liability company in the state is using the exact name selected. To find out if a business name is available, call the Secretary of State and they will do an immediate computer search. The search is only for business names registered with the Secretary of State, and does not include business names registered only a county clerk.
If a corporation will transact business under names other than that stated in the articles of incorporation, the corporation must file an Assumed Name Certificate with the Secretary of State, and with the county clerk in which the principal office and registered office of the corporation are located.
