In some cases, in order to ensure you're the card owner, we may ask you to confirm your card. If you see a "confirm credit card" link in the card details section of your PayPal Wallet, you'll need to confirm your card before you can use it with PayPal. If you don't see this link, you can begin using your card right away.
If you do not act to confirm your card by entering int he 4-digit code (or your card cannot be confirmed), the charge will be refunded 75 (60 days in Brazil) days from the date of the charge. Based on certain jurisdictions (such as Brazil), the credit may not actually post to your card for up to 30 additional days.
If you remove your card or close your account during the time frames above, the return of the credit may not process. In these instances, you may need to contact PayPal Customer Service to have the charge refunded.
