    EAN-8
    In This Topic

    EAN-8 barcode is used on small packages where an EAN-13 barcode would be too large. Similar to EAN-13, EAN-8 uses only numeric characters and a check digit. This barcode accepts only seven numbers as a string to calculate a check digit (CheckSum) and add it to the eighth position. The check digit is an additional digit that can be used to verify that the barcode has been scanned accurately.

    The below image displays EAN-8 barcode in a PDF document.
