Barcode terminology
Barcode term Description
Check digit The check digit is always the last character and ensures accurate readĆ
ings when barcodes are scanned.
Follett Classic A family of barcode symbologies consisting of barcodes that contain
seven visible positions or fewer. The Follett Classic family of symbologies
includes: Code 39, Interleaved 2 of 5, Codabar, LabelCode IV, and LaĆ
belCode V.
If your barcodes fit this description, choose Follett Classic as your
symbology.
Generic Means the barcode symbology does not use a check digit.
Mod 10 Symbologies with Mod 10 check digit calculations can be used for barĆ
codes with all numeric characters. The 10 numeric characters are used
to calculate a check digit algorithm.
Mod 11 The same restrictions apply to symbologies using the Mod 11 algorithm
as to those that use Mod 10. The only difference is that the check digit
in Mod 11 can also use the +" symbol.
Mod 43 The Mod 43 check digit uses the 26 alpha characters, the 10 numeric
characters, and these symbols:
Ć . $ + % / and the space.
The item number portion of the barcode must still be all numeric.
If your barcodes contain alpha characters for the type identifier or locaĆ
tion code, you will probably choose a symbology that uses a Mod 43
check digit.
