I have a question related to the batch number on final product. In most of the goods, a batch number is printed or embossed in the final product. This number usually is eye visible and in almost all cases is a meaning number (concatenation of Julian date, line number, plant identification, time, shift, etc.). My question here is, is there a legal requirement to have a meaning number as batch number on the final product for the consumers? Instead, could we print online only a unique number in the final product that can only be decoded (retrieve all traceability information) by a company system? In case of recall, is there any issue related to it? I suppose that if we need to do a market recall, we cannot provide via TV or Journals all the printed codes as the list would be huge compared with a meaning number. My question here is really to know if this is regulated or open as long as we can retrieve the traceability info by other means.
Thanks in advance for your clarifications and support.
