Not all maestro cards have an issue number.

• If the main number of your Maestro card has 16 digits, there is not an issue number. 
• If this number is more than 16 digits, there will be an issue number on the front of the card, near the expiry date. It will simply say 'issue' followed by a one or two digit numbers.
• If there is not an issue number, you will need to provide the start date instead. All Maestro payments will require one or the other.
  

To complete your payment online, you will also need to provide the last three digits of the number printed on the signature strip on the back of the card.
