When you register a company, the registration documents are listed on the Secretary of State website. You have the option of ordering plain copies or certified copies from the State Government.
Some banks will require a certified copy of your filing document. If you are opening a physical store, some states and cities will require you to display a certified copy in a visible place.
If you are doing business with another company and they require a copy of your formation documents, most companies will accept a non-certified copy of your documents. You can access a free non-certified copy on your state’s online corporate database.
