You can add or update your billing address and payment information at Kobo.com

Before you update your account with a new credit card, here are a few things to remember:

• Enter your billing address and postal code exactly as it appears on your credit card statement.
• If you have trouble purchasing a book using a new credit card, try entering abbreviated and full versions of the street names. For example 'Street' and 'St.', or 'Drive' and 'Dr'.
• If you're a U.S. customer, enter the postal code in full. For example, 00000-0000.
• Ensure that you're entering the address that's associated with your new credit card.
• Make sure that your new credit card has been activated.
