Q: When I purchase the AppleCare Protection Plan, do I need to register it?
A: If you purchase the AppleCare Protection Plan at the same time as your Mac, iPhone, iPod, Apple TV, or Apple display from the online Apple Store, Apple will register the AppleCare Protection Plan for you. If you purchase your AppleCare Protection Plan and your covered product separately or elsewhere, you will need to register your AppleCare Protection Plan.
Your AppleCare Protection Plan coverage starts from your hardware purchase date. Registering your AppleCare Protection Plan at a later date does not extend your coverage. In fact, there are many benefits to registering your AppleCare Protection Plan as soon as you purchase it.
For example, after you register, Apple will have your hardware, AppleCare Protection Plan, and personal contact information on file. When you contact Apple for service or support, Apple can access your information right away and start addressing your issue, rather than spending time verifying your eligibility.
