Jah sorry, kozben megtalaltam a paypal help centereben:

How do I confirm my address?

To confirm your address, you will first need to add a credit card to your PayPal account. If your credit card company supports the Address Verification System, PayPal will check that the address you provided for your account matches the billing address that your credit card company has on file. You may be required to complete the Expanded Use enrollment process, to activate your credit card. Your address may be confirmed after the Expanded Use enrollment process has been successfully completed. Please note that because not all credit card companies are currently able to confirm an address, only some UK and Canadian addresses may be confirmed at this time.

Akkor modositanam ugy a kerdest, hogy a raiffi bank tud cimet konfirmalni?
