Frequently asked questions
Which barcode format should I use?
CODE128 is the most flexible for general use; EAN13 and UPC are standard for retail products (with specific digit-length requirements); CODE39 is common in logistics and inventory.
Why does my value show an error for a format?
Some formats have strict requirements — EAN13 needs exactly 12-13 digits, UPC needs 11-12 digits, for example. Switch formats or adjust your value to match.
Can I use this for retail products?
The generated barcode is scannable and follows the selected format's encoding rules, but make sure any product barcode numbers (like GTINs) are properly registered before using them commercially.
