In simple terms, this means that you will have to apply for a different debit card - with a different number - and change ANY OTHER accounts where that modification takes effect.
So if you use your debit card number to deal with Amazon or Paypal (or similar), you will have to update those accounts as well with the new debit card number, once you receive it.
