RMA number - Short for returned merchandise authorization number - an alphanumeric identifier used by BenQ that indicates a user has been authorized by the BenQ Team to return a product to the manufacturer for repair or exchange. An RMA is similar to a tracking number in that it identifies a transaction, and both parties can get information on the progress of the transaction by using the RMA number. You must return the Product to BenQ unless otherwise directed by BenQ to a BenQ Authorized Service Provider.
