Thanks Jim
The reason why I "guessed" UPC-A and UPC-B is that, in documentation, this symbol set is together with the code 3 of 9 barcode symbol set.
While documentation specifically mentions Bar code for 3 of 9 symbol set id, it doesn't say anything for these symbol sets.
The symbol set id's are OCA-A(0O) and OCR-B(1O). (zero letter O and 1 letter O).
Cheers!
