When paying by credit card we check with our payment processor that the credit card number, CVV number (3 or 4 digit code on the back of the card), your name and address match the details that your card issuing bank has and to make sure the card is still valid.
On some occasions we are told that the card details are not correct or the card is not valid and this will result in a failed authorisation. If this happens, please check you have typed the card details correctly.
If the problem continues to persist, please contact your bank for an explanation as to why your card is not being authorised.
As an alternative, when subscribing to FT.com you can choose to pay by PayPal where you can either pay by credit/debit card or directly from your bank account.
