Why was my credit card number or expiry date updated automatically?

To prevent any failed payments, and to save you from having to update your credit card details manually, we may automatically update your credit card number or expiry date when new information becomes available from your card issuer.

What information does the card issuer provide to PayPal?

The card issuer provides your new card number and/or expiry date. We don’t use or store your card CVV and the card data we receive from your card issuer is encrypted. Your card issuer can notify us of any changes to your card (except for name changes), including if the card account has been closed.
