what is rma number
A: An RMA is a âReturn Material Authorizationâ. An RMA is generally issued by a merchant to their customer to approve, identify, and track the return of a good (package) from the customer back to the merchant. RMA numbers are central to the FedEx Return System product. In order to print a shipping label, the FedEx Return System software application uses the customerâs RMA number as a unique âkeyâ to automatically determine where the shipment is going, what service will be used, and what account number to bill.
