State Business Registrations

State Corporate Registrations

Corporations in the USA register at the State Level, usually with the Secretary of State’s office. Before spending any money you can check most state existing company names at the office links provided below. Some states also provide state trademark filing (separately from the Federal USPTO) but most of these have fallen into non-use or irrelevance.

Many of these offices also provide special information on their websites as to how to register different types of businesses. Some even have special help for small and minority owned businesses.

NOTE: Sole proprietorships, and other small partnerships that do not incorporate, are usually only registered at the local county level. To check those names, visit your local county’s business services office. As long as there is no exact match, the name will usually be approved – but they won’t check state or federal registrations for you…so be cautious of infringing on the name of some much larger business name.
