GTIN-14 Shipping Container Barcodes

If you need to determine what the checkdigit is for your GTIN-Shipping Container Barcodes based on your UPC barcode, here is an easy way to do this.

A Shipping Container Barcode is configured as follows:

XYZZZZZZZZZZZA

X is the packaging indicator. Although you can use 0 through 7, we recommend 1 through 7 since this will minimize problems with dropped zeros in Excel.
Y is always 0 (Zero)
Z is the first 11 digits of your UPC barcode
A is the check digit

The way that you can determine the checkdigit is by creating an Excel Spreadsheet, enter the numbers X through Z into cell A1 and enter the following formula into cell A2

=A1 & MOD(10 – MOD( SUMPRODUCT(MID(A1, {1,2,3,4,5,6,7,8,9,10,11,12,13}, 1) * {3,1,3,1,3,1,3,1,3,1,3,1,3}), 10), 10)

If you have software and want to do it yourself, you will use an Interleaved 2 of 5 symbology with a mod 10 check digit.
