Calculate Your Check Digit

 

The all-important check digit ensures our numbers are correct

 

All Global Trade Item Numbers (GTINs) and Global Location Numbers (GLNs) end with a computer-generated check digit. This digit is the result of an algorithm (called the Modulo-10 algorithm) which uses the other numbers in the GTIN or GLN to ensure its correct composition. 

 

You can use the below check digit calculator to obtain your barcode check digit.
