Register Powerbeats pro through android beats apps

Hi moonlight6,

Thanks for contacting Apple Support Communities!

We understand that you're attempting to register your Beats but the serial number is invalid.

Check out this resource which explains where you can locate your Beats serial number to verify the serial number is correct: Find your Beats serial number - Apple Support

"Powerbeats Pro

Check the inside of the case.

To find the serial number of your Beats product when it's connected to your Android device or paired in the Beats app for Android:

1. Open the Beats app.
2. Scroll to "Under the hood: Serial number.""

If you're still unable to register your Beats, we'd suggest that you contact Apple to register your Beats for you. You can reach them here: Contact Apple Support 

Take care!
