Frequently Asked Questions (FAQ)
Which barcode format should I use?
CODE128 is a great general-purpose choice that supports letters and numbers. UPC and EAN-13 are numeric-only formats typically used for retail products sold in North America and internationally, respectively. CODE39 is an older format that also supports letters and numbers but is less compact than CODE128.
Are the generated barcodes suitable for commercial use?
Yes, the barcodes are generated according to standard specifications and are fully scannable. However, for official retail products, you typically need to purchase a registered GS1 company prefix to ensure your UPC or EAN numbers are unique worldwide. This tool generates the barcode image from the number you provide; it does not create registered GS1 numbers.
What happens if I enter invalid data for a format?
The tool includes validation. For example, if you try to generate a UPC barcode (which must be numeric) with letters, an error message will be displayed for that specific entry, while other valid entries will still generate correctly. This helps you easily identify and fix issues in bulk lists.
