Why has my PayPal code expired?
When you request another PayPal code, a new 4-digit code is generated and the previous one expires. You need to use the new PayPal code to confirm you card.
A new PayPal code can be requested up to 2 times. All corresponding charges are refunded to your card after you've entered the latest PayPal code online. Depending on your card issuer, the refund may take up to 30 days to appear on your next card statement.
