As part of the verification process, you will receive a postcard at your current postal address with a unique 8-digit code printed on it.
You must enter this verification code into your Digital Stable as soon as you receive the card - this completes the verification process.
While you're waiting for your verification code to arrive, you can add equines to your Digital Stable.
However, you won't be able to change any details of your equines before you enter your verification code.
It's therefore really important for you to enter your verification code so you can update your equine's details.
