How to avoid GTIN/UPC, Bill of loading numbers from being detected.

Hi,

In our scan we get a big amount of GTIN/UPC codes or BOL (Bill of loading) numbers, which eventually are False positives. But these are detected as they pass the criteria of a valid credit card number.

Is there a way we can avoid GTIN/UPC codes or BOL to be detected to reduce the false positives.

Regards,
