Questions people actually ask
Which format for retail products?
EAN-13 for most of the world, UPC-A for North America. Both need exactly the right digit count — the tool tells you when you're off.
Will supermarket scanners read these?
Yes, at print quality. Print at 300 DPI or higher, keep bars black on white, and don't stretch the proportions.
