What is required when purchasing AppleCare for Apple products?

When purchasing AppleCare for Apple products, it is essential that the purchase of AppleCare is made on the same receipt as the purchase of the Apple product itself. This requirement ensures that the AppleCare coverage is directly linked to the specific device purchased, allowing for streamlined activation and registration of the warranty. Having the items on the same receipt facilitates verification of the product's purchase date and eligibility for coverage, which are critical factors for the effective use of AppleCare service. This process helps maintain accurate records for service and support in the future, maximizing customer satisfaction and warranty effectiveness.
