Corporate identity is a company's visual presence, which involves the corporate logo and design strategy for corporate marketing collateral. Corporate identity does not encapsulate brand identity, which is best defined as the soul of your company. However, a corporate identity may, and often does, reflect a brand identity. But some ad agencies, marketing companies and graphic design agencies would have you believe that brand identity is the same thing as corporate identity and that changing a logo or design strategy will change the brand identity.
