I’m trying to pair my kindle to AirPods.it says I need a PIN number ?

Hello michele3_3,

Thank you for posting to the Apple Support Communities. 

The PIN number here may be listed in the settings of your Kindle device. The following Apple Support articles explain how to set up and pair your AirPods with new devices, there is no mention of a PIN number associated with the AirPods: 

• Set up AirPods with your Mac and other Bluetooth devices
• If your AirPods won't connect

If you are unable to pair your AirPods using the instructions above, please contact  Apple Support directly for more help. 

All the best!
