I am not successful a registering my magic trackpad. Any suggestions?

Do I need to register my Apple product?

The Apple Product Registration website is closed.

If you’re trying to register an Apple product, chances are it’s already registered. Most Apple products can be registered when you turn them on for the first time and begin the setup process. Service and support for your Apple product are linked to its serial number, so it’s OK if you don’t register it. If you'd like to check the service and support coverage for your Apple mobile device or computer, click here.

If you have previously registered an Apple product, then you have a: Your Support Profile for Registered Purchases.

Apple does not maintain a database of peripheral devices.
