When I try to add a payment card to my account a general error comes up.
The most common cause of this is the extra layer of security required that involves confirming the cardholder postcode when adding a card to your account.
Please Note: This is not always your home postcode, it is the postcode that the card is registered to.
If you have moved house since you were last issued a card by your provider your card may still be registered to the old address, or it may have been entered incorrectly when you gave them your new address.
