If you believe the information shown for your product is incorrect, you can submit your proof of purchase online
Your sales receipt is needed for Apple’s Limited Warranty, AppleCare Protection Plan, and AppleCare+ validation, so be sure to keep it in a safe place. Apple’s Limited Warranty is the same whether or not you register.
