Once your order ships, You will be updated with an AQ/SF/4PX Express Postal tracking number but once your package reaches the United States you will also be able to track it through the USPS tracking site with another tracking number. Both tracking numbers will provide the same information, however once your package reaches the United States you will be able to contact USPS post to get an update on the expected delivery date. Due to the recent increase of package theft, we advise you to contact USPS with your tracking number to arrange a signature upon delivery. Although we ship all packages requesting this, they do not always comply with shipments coming from China which is why we advise you to take extra precaution. We will not be responsible for stolen packages. Also please note that we are not able to cancel or call an order back once it is in transit.
