GS1.org Check Digit Calculator


"What is a check digit?

The last digit of all fixed-length, numeric GS1 Identification Keys is a check digit that ensures the integrity of the key.

All GS1 ID Keys need a check digit, except Component/Part Identifier (CPID) and Global Individual Asset Identifier (GIAI). Global Model Number (GMN) includes a pair of check characters rather than a single check digit.?
