Gerald,
What are drtails by the way? Anyway, I am using bar codes in one of my app and it's nothing more than a font. The field that I'm barcoding is a character field and I don't think length matters. Not to mention, well here's an example of the data that being barcoded...
999-9999-99999
HTH.....
