The EAN/UPC Add-On Symbols were designed to encode information supplementary to that in the main barcode symbol on periodicals, hardback, and paperback books. Because they provide reduced security, use of Add-On Symbols shall be limited to applications where rules in the application specification governing data format and content provide appropriate safeguards.
A two-digit Add-On Symbol may be used in specific applications to accompany an EAN-13, UPC-A, or UPC-E Barcodes. In general, the two-digit Add-On barcode is positioned following the right Quiet Zone of the main symbol but can be drawn without requiring the presence of the mail symbol.
