The Manage Orders page

Your Manage Orders page provides a customizable view of all your orders on all sales channels. You can view all orders within a given date range or use Search to filter specific types of orders. To view the page from your seller account, click Orders, and then click Manage Orders.

Here is some additional information:

• Buyers' phone numbers will not be visible for orders that are fulfilled by Amazon. If you must contact the buyer, follow the steps listed on the Contact a buyer page.
• For seller-fulfilled orders, we provide you with a phone number that connects to the buyer during the fulfillment period. After delivery is complete, this phone number will no longer connect to the buyer. For more information, please visit Prohibited seller activities and actions.
• You must confirm shipment of the order with Amazon within 7 business days after the “ship by [date]”. Otherwise, Amazon will automatically cancel the order and you will not be paid, even if you shipped the order.
• When you confirm shipment for even one item in an order, we charge the buyer for the entire order. If the entire order is not confirmed, you will see the "Shipment is late" status in Manage Orders and a warning message on your seller account home page. These will appear even if you have refunded the remaining items in the order.
