BARCODE & SCAN OPTIONS
173
The add-on symbol is appended to the EAN-13 barcode. The process is similar for
UPCE, UPCA, and EAN-8 barcodes. Note that all the UPCE, UPCA, EAN-8, and EAN-13
formatting and conversion options are in effect. The following table should help explain
the effect of various options for EAN-8 barcode 12345670 + 12.

The add-on symbol contains neither a check digit nor a terminating guard band. Every
effort has been made to reduce the decoding error; however, it is likely to decode a
partial scan of a 5-digit add-on symbol as a 2-digit add-on symbol. It is strongly
recommended that the minimum security level be set at 2 while decoding add-on
symbols. Since the decoder takes a conservative view on the add-on symbols, it is
likely that the add-on symbol will be missed in the auto-discrimination mode. Auto-
discrimination mode should then be avoided.
