An honest word about retail barcodes
Anyone can draw an EAN-13 or UPC barcode — the format is just a font for numbers. But a barcode that shops can actually sell under must use a number issued to your company by GS1 (the global registry), because two products with the same number would collide at every till. Use this generator freely for your own warehouse, office, school or stockroom; for products going into retail, register with GS1 first, then generate the artwork for your issued number here.
Frequently Asked Questions
Which format should I use?
Code 128 for general internal labels (it encodes letters and numbers). EAN-13/UPC for retail-style numbers. Code 39 for simple uppercase labels. ITF-14 for outer cartons.
The value was rejected — why?
Retail formats are strict: EAN-13 needs 12 digits (the 13th is a check digit the tool calculates), UPC needs 11–12. The error message tells you what the format expects.
