To use any kind of credit or debit card with PayPal, you must link it to your PayPal account. Link the card by adding the card account number and billing address to your PayPal account profile. Then use the card by adding money to your PayPal account from the linked card. The problem with gift cards comes in when they aren't registered in your name. When you try to link a gift card that isn't registered, the PayPal system checks for a name and billing address and doesn't find it, so it rejects the card. Contact the issuer of the gift card. Some issuers allow you to register gift cards. Make sure the name and address exactly match your PayPal information. PayPal doesn't guarantee this will work, but typically you can link a gift card this way. If the gift card issuer won't let you register the card, you can't use it with PayPal.
