How do I register my AirPods
Question marked as
When you setup your AirPods and pair them with your iPhone they should automatically be added to your account.
See the footnote in the 'Add a device to the list' section of:
Check your Apple ID device list to see where you're signed in - Apple Support
"Your AirPods will appear in the Find My app, but they won't appear in your Apple ID device list. You can remove your AirPods from your account using Find My. Devices running iOS 7 or earlier or OS X Mavericks or earlier won't appear in your device list."
