Could someone please tell me how I can delete my Credit Card and Debit Card 'last numbers' from my Amazon Account? They seem to keep this last number all the time.
They keep ALL the numbers, just the last 4 show on your account details so you know which card to use (eg I have mine set up for 3 cards with one of them as the default). If you delete your card then you'll just have to put it back in again next time you buy something. I've had an Amazon account for 10+ years and have never had a problem with fraud. I think Amazon is probably now the safest and most trusted online shopping medium there is.
