An ISBN bar code is a slightly varied EAN-13 bar code. Before creating an ISBN bar code, however, it is highly recommended that you contact the International Standard Book Numbering (ISBN) agency at (908) 665-6770 to obtain information on creating book industry bar codes.
To create an ISBN bar code:
Use EAN 13
Character set 10 digits (0-9)
Start/stop character 1 start/stop character. These are automatically inserted. 1 separator
Self-checking yes
Check digit calculation yes, 1 check digit
