<P> The exact formula of Coca - Cola 's natural flavorings ( but not its other ingredients , which are listed on the side of the bottle or can ) is a trade secret . The original copy of the formula was held in SunTrust Bank 's main vault in Atlanta for 86 years . Its predecessor , the Trust Company , was the underwriter for the Coca - Cola Company 's initial public offering in 1919 . On December 8 , 2011 , the original secret formula was moved from the vault at SunTrust Banks to a new vault containing the formula which will be on display for visitors to its World of Coca - Cola museum in downtown Atlanta . </P>
