Once you have purchased an item on StockX, the Seller packages the item and drops it off at a shipping carrier for delivery to a StockX Authentication Center. The Seller has two business days to ship their item to a StockX Authentication Center—three for new release shoes and streetwear and five for Supreme items, due to the nature of their drops and deliveries.
 

As a Buyer, you can expect to receive the following email notifications from StockX after you purchase an item:
 

1. An order confirmation (including order number) when your purchase is completed
2. A confirmation when the Seller ships the item to the Authentication Center
3. A notification when your item has been verified and shipped
4. A confirmation that your delivery has been received

You won't receive a shipping confirmation until the item has been verified and is en route to your delivery address, but you can always check the status of your order prior to receiving your order number by viewing your pending orders from the StockX Buying tab, which you can navigate to  by clicking  My Account > Buying.
