It’s an extra layer of security that’s used to register and manage an email PayID. When you set up an email PayID, we’ll send you a verification code to that email address. We’ll also email you a verification code if you want to lock, unlock, transfer or close the email PayID.
Email verification code works in a similar way to SMS code, but remember, it’s used for different things. Email verification code is only used for your particular email PayID, whereas an SMS code is used for a PayID linked to your mobile number (plus other things, like increasing your payment limits or paying a new recipient). This means you can’t use an email verification in place of an SMS code (and vice versa).
