Method, examples and limits
The check digit uses the first twelve digits weighted alternately by 1 and 3; the final digit brings the sum to a multiple of 10. 400638133393 becomes 4006381333931. SVG downloads retain black bars, a white background and side quiet zones. Creating an image does not assign a commercial GS1 number or guarantee every print will scan: check dimensions and scanning on the final medium.
