Frequently asked questions

Will the code be accepted by stores or inventory systems?
The tool generates the graphical representation of the code; it doesn't assign official commercial identifiers (such as those issued by GS1), so its acceptance depends on you having a correctly assigned identifier.
Does it validate the check digit?
Yes, independently for EAN-13, EAN-8, UPC-A, and ITF-14, using the standard weighted-sum algorithm.
