Frequently Asked Questions
Which format should I use?
CODE128 for general labels and anything with letters — it accepts any text. EAN13 for retail products sold internationally (13 digits). UPC for products sold in North America (12 digits).
Why did my EAN13 barcode fail?
EAN13 needs exactly 12 or 13 digits — letters or the wrong digit count are rejected, and the tool tells you why instead of producing a broken barcode.
Are the barcodes scannable?
Yes, when printed at a reasonable size with good contrast. Tiny or low-contrast prints are the usual reason a scanner struggles — keep the bars dark on white and at least a few centimetres wide.
Is anything uploaded?
No. Barcodes are generated entirely in your browser from the text you type.
