FAQ
Which barcode type should I choose?
Use EAN-13 for global retail products, UPC-A for US/Canada retail, CODE39 for industrial/alphanumeric IDs, and Code128 for compact general-purpose encoding.
Is barcode generation done on this page only?
Yes. All generation runs client-side in your browser and your input is not uploaded by this tool.
Why is my value invalid?
Some barcode formats require numeric-only values, fixed lengths, or valid checksums. The validator shows what needs to be corrected.
