Before you order your GTIN-14 Shipping Container Code, you must have a UPC or EAN for the product. If you do not have your UPC, you will either need to go to the GS1 or a UPC reseller like Nationwide Barcode or UPCBarcodes.com
A Shipping Container Barcode (also known as a Shipping Container Code, Shipping Container Symbol or a GTIN-14) is used on the outside of your master cartons and recommended or required by many mid-to-large retailers who have automated their incoming inventory processes
The UPC Shipping Container Symbol is very similar to the Universal Product Code. This symbology used is called an interleaved 2 of 5 (ITF). The major difference between this barcode and a UPC barcode are the lines around the barcode graphic. These are called Bearer Bars.
The Barcode is comprised of 4 groups.
1) – Packaging Indicator. You can select any number you want between 0 to 7 for the first digit. If you have a container that has 12 units inside and another container that has 36 units inside, you will assign different numbers to each. This is very flexible. the only time you should use zero as a packaging indicator is if you are creating an item that is a mixed carton. You should only use a packaging indicator of 0 if there is only a single item in the container (such as a TV or Washing Machine)
2) If you are having us create the GTIN-14 from a UPC, the next number is a ZERO. This is required.
3) The next 11 digits are the first 11 digits from the UPC barcode used for the item inside.
4) The final (14th digit) is a check digit….we create this with our software
