Please welcome jamsebond094, our newest. 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. This is obviously true for any two sequence numbers with distance of 0x8000 between them. Furthermore, implementing serial number arithmetic using two's complement arithmetic implies serial numbers of a bit-length matching the machine's integer sizes; usually 16-bit, 32-bit and 64-bit.
