How to calculate a barcode check digit

You can use this form to calculate the check digit (final digit) for a GS1 identification number such as a barcode number (GTIN), a Global Location Number (GLN), a Serial Shipping Container Code (SSCC) or a Global Service Relationship Number (GSRN). Simply enter your prefix and chosen item reference digits in the left box and click the Calculate button. Your complete GS1 number will appear in the right hand box.
