Check Digit Calculator for GS1 Identifiers
The last digit of every type of GS1 identifier is a calculated check digit. In order to ensure that all of the previous data was correctly decoded by a scanner, the calculated check digit prevents errors and misreads. The technical name for the check digit is modulo 10 but we have created the following calculators below to calculate the respective check digit for each type of GTIN.
