A Letter of Assignment or LOA is received after an order is completed. The LOA is used only in areas where units are sold first out of the stack. For example, if you place an order for 20x40' units off the top of the stack, the unit numbers will not be known at the time of the order. Instead, you will have a "blanket" Release Reference. Upon receipt of all 20 units, BestBuy Container will confirm with the terminal or yard which unit numbers were received and apply the specific unit numbers to your release. You will then receive a Letter of Assignment indicating the units received. This is for your records.
