In common parlance, many people know the GTIN as a barcode, but technically the GTIN is the number below the barcode symbol itself, and can therefore also be used for other technologies such as 2D barcodes and RFID tags.

The last digit in all GS1 numbers is a check digit, which is calculated from the preceding digits. The check digit must be correct before the barcode can be read and used as a check of both the number and the barcode.
You can calculate your check digit by entering either 7, 11, 12, 13 and 17 digits in the calculator in the link below, corresponding to e.g. UPC, GTIN-8, GTIN-13, GTIN-14 and SSCC.
Check digits are calculated according to the modulus 10 algorithm.
