When you try to add a card to your account, we match the address you enter in our system with your credit card billing address. If you receive a message telling you that your credit card address can't be verified, you should confirm that the credit card postcode you've entered on our site is exactly the same as the postcode that appears on your billing statement.

If you've verified this information, please contact your bank or credit card issuer to determine why they aren't accepting your credit card on Facebook.
