Go to the state website for business incorporations for the state where the corporation maintains its official registration. If you do not know where the corporation maintains its official registration, go to the state website for any state where the corporation maintains an office or business location.
Access the state's business entity database. Enter the name of the corporation in the search field and pull up the corporation's public information. Many states append a copy of all of the corporation's filings -- including the certificate of incorporation -- to its record in the database.
Navigate to the "fees and forms" section of the state website if your state does not append the image of the certificate of incorporation to the database record, or if you need a certified copy of the certificate. Access the state's schedule of fees. The schedule will include the instructions for sending in a request for anything listed on the schedule of fees.
Fill out an order form. The state usually provides a downloadable order form where you can indicate the name of the corporation, the document you need, the address to which it should be sent and how you intend to pay. Send the order form to the state office with payment.
