If you're looking for your Ploom registration code, it's easy to find it.

Have a look at the leaflet in your Ploom box.
You'll be able to see a QR code and a 16 character alphanumeric code just below it. You can use this code to register your device.
Just log in to your account (or create an account if you do not already have one), go to your profile and click on my 'My Devices'. Choose 'Register a new device" and follow the instructions. 

If you are having any issues, please contact the Ploom Care team and we'll be happy to help.
