It's easy to revise shipping and billing information for an order you placed with Amazon.com, as long as the order has not yet entered the shipping process. (To revise the information for an order you placed with an Amazon Merchant or Amazon Marketplace seller, please contact the seller directly.)

If we can recognize you as a customer with any unshipped orders, you will see a box to the right. Click the relevant link in that box to visit the order summary page. (If you do not see that box, sign in to Your Account, and select the order you want to revise.)

On this page, you can change your shipping address, payment method, shipping method, number of shipments, and billing address by clicking the Change button next to the relevant listing. For security reasons, when you change your shipping address you will need to reenter your credit card number.

If an order is marked as "Shipping Soon," this means it is being prepared for shipment and cannot be changed by you or by our customer service department. If the package will not reach you because of an incorrect address, it will be returned to us as undeliverable and you will need to place a new order.

If you receive a message that we were unable to authorize payment from your bank account, read more about what you can do.

If you receive a message that we were unable to authorize or charge your credit card, please check with the issuing bank for your card. Credit cards may be declined for a variety of reasons, such as a technical error during processing, and we do not have access to further information.

If you placed your order with Amazon.com, we will try charging the same card again if you do not submit updated information. Typically, we attempt to charge a credit card daily for one week before canceling your order. To update your credit card details or submit a different payment method, visit Your Account and select the link to "Change payment method."

If your order was for a gift certificate, you will need to cancel the declined order and place a new one.

If the order was placed with an Amazon Merchant, the order has been canceled. You are welcome to place a new order using a different payment method.

If the order was placed through Amazon Marketplace, you will have an opportunity to resubmit payment. If the second attempt to process the charge also fails, your order will be canceled.
