It was at the end of 2000 that IATA definitively adopted Resolution 606, which aims to standardise labelling in the world of air freight.
For the carriage of cargo, identification label(s) in the form of a bar-coded label may be used and attached to each package, adjacent to the consignee's name and address where space permits. In certain cases, more than one label may be required, such as when shipments have labels applied by different parties, e.g. shippers, forwarders, airlines, or when the amount of optional information does not fit onto the label stock in use.
For purposes of this Resolution, a bar-coded label is one containing barcode(s). The label may be printed automatically on demand or preprinted.
