APPENDIX BARCODES
EPT031055 Issue 2 September 2017 B-3
BARCODE TYPES SUPPORTED 
1-D Barcodes 
In the table below, the types of 1-D barcodes supported are summarised,
with the type and number of characters specified for that barcode type. The
term “any” means capital letter and number characters; in some cases
additional characters are defined, but lower case letters are not permitted.
Only Extended Code 39 and the EAN 128 and Code 128 codes provide
symbols for the full ASCII character set.
There are many named barcode types which are actually derivatives of
major types. To avoid the table becoming excessively complex, only
generic names are used, e.g. ISBN, ISSN and JAN coding schemes are all
variants of the EAN scheme. There are several coding schemes (such as
DEFCON) which are actually Code 39, and some countries use Code 128
under other names for mail tracking (as in the UK).
