The entity number is the identification number issued by the California Secretary of State when the entity registered in California. You can use the California Secretary of State Business Search to find an Entity Number for a particular CA entity. If searching for a corporation by entity number, the letter “C” must be entered followed by the applicable seven-digit entity number.
