Frequently Asked Questions
Which barcode format should I use for retail products?
EAN13 is the standard barcode format used on retail products in most of the world, while UPC is more common in North America — check with your retailer or distributor for their specific requirement.
Why does my input show an error?
Some formats have strict requirements — for example, EAN13 requires exactly 12 or 13 digits and UPC requires 11 or 12 digits. If your input doesn't match the format's rules, the generator will flag it as invalid.
Can I use letters in my barcode?
CODE128 and CODE39 support letters and numbers, while EAN13, UPC, ITF14 and Pharmacode are numeric-only formats.
