Why is my barcode number invalid?
The usual causes are a mistyped digit, a number copied with spaces or hyphens still in it, a UPC-A pasted into a 13-digit field without its leading zero, or a number that was never a valid GTIN in the first place.
If you got the number from a supplier or an online listing and it won’t validate, it may not have been legitimately assigned. See our Retail Barcode Packages.
How is a barcode check digit calculated?
The last digit of every GTIN is a check digit, worked out from the digits before it. Scanners use it to catch mistyped or misprinted numbers.
One check digit calculation method uses Modulo 10. Working from the right, each digit is alternately multiplied by 3 and by 1; the results are added together, and the check digit is the value that brings the total to the next multiple of 10.
70119720000, with the check digit missing. Multiplying and adding gives 65. The next multiple of ten is 70, so the check digit is 5, making the full number 701197200005.
