There are two ways to verify your account: The first way is to log in to your account and click on the Welcome button in the upper right corner. Then select My Profile and find the ID section. There you will be able to add your ID by clicking on Add ID and Upload. If the first method doesn't work, the second method is to send a copy of your ID and an account verification request to KYC.co@betfair.com from the email address you used to register with Betfair
