A delivery management system includes a drug wrapping 140, a delivery container 26, a delivery management device 7, and a barcode sheet 137. The barcode sheet 137 includes a barcode label 137c indicating a serial number related to a drug, a barcode-image portion 137e indicating the serial number related to the drug, and a barcode label 137d indicating a delivery-container ID related to the delivery container. When the drug wrapping to which the barcode label 137c separated from the barcode sheet is attached, the delivery container, and the barcode sheet from which the barcode label 137c has been separated reach a delivery destination, the drug wrapping is verified using the barcode label 137d attached to the delivery container and the barcode-image portion 137e.
