What is the GTIN-14?
The GTIN (Global Trade Identification Number) is a 14-digit identifier. If the first digit is 0, it signifies a single copy; the check digit does not change. If the first digit is other than 0, it signifies a different delivery profile, i.e. carton or pallet, and the check digit changes. Duke will eventually provide for the GTIN in our system but does not expect to utilize it much in trading.
