Delivery Confirmation Number - The delivery confirmation number is not a tracking number, it only shows when the item arrives at your location. If you check the delivery confirmation, it will read "The U.S. Postal Service was electronically notified by the shipper on (date) to expect your package for mailing. This does not indicate receipt by the USPS or the actual mailing date. Delivery status will be provided if / when available. Information, if available, is updated every evening. Please check again later" All shipments are picked up at our warehouse by the USPS. The information is never updated until it arrives at your location.
