You must use valid 'gtin' attributes, so the checksum digit has to be present and correct. The 'gtin' attribute is not restricted and it is not a coupon.

The ISBN for books is a 10 or 13-digit number. The 13-digit number is the modern format, so do not include the 10-digit number if you know both. If you only have the 10-digit number it must be converted to a 13-digit number.For multipacks you need a 14-digit number.
