What is a Barcode?

A barcode is a machine-readable optical label that encodes information about a product or item. Barcodes consist of parallel lines (bars) and spaces of varying widths that represent data. When scanned with a barcode reader or smartphone camera, the encoded information is instantly decoded. They are used worldwide for tracking products, managing inventory, and speeding up retail checkout processes.

Frequently Asked Questions

Q: Can I use these barcodes commercially?
A: Yes. Barcodes generated here are free for personal and commercial use. For official retail use (EAN/UPC), you may need to register with GS1 for a globally unique number.

Q: Why does EAN-13 require exactly 12 digits?
A: EAN-13 automatically calculates and appends the 13th digit as a check digit. So you provide 12 digits and the standard adds the last one.

Q: What resolution should I use for printing?
A: Use HD (3×) for standard print. Use Ultra 4K (6×) for large-format printing, packaging, or high-resolution labels to ensure every bar and text character is razor-sharp.
