How quickly does my new Prime membership begin after I purchase a Fire?
Prime membership benefits are applied during registration of your Fire phone. For online purchases on Amazon.com, registration occurs typically when the device is shipped, unless it is marked as a gift. For gift purchases and for purchases from authorized resellers in the United States, registration occurs during device setup. Once your Amazon.com account is registered on the device, membership is effective immediately. You will receive an email as confirmation that Prime benefits have been applied to your account.
