Which Format Do You Need?
- EAN-13 — global retail standard (groceries, books, electronics outside North America).
- EAN-8 — compact EAN for small packaging where a 13-digit code does not fit.
- UPC-A — North American retail standard (Walmart, Target, US grocery chains).
- UPC-E — compressed UPC for very small product packaging.
- Code 128 — high-density alphanumeric. Standard for shipping labels, warehouse internal SKUs, and logistics.
- Code 39 — older alphanumeric standard, still required by US Department of Defense, automotive, healthcare.
- ITF-14 — printed on shipping cartons to identify case quantities of consumer products.
For Retail and E-commerce Sellers
If you list on Amazon, Walmart, Shopify, or any major marketplace, you need a valid GTIN (UPC or EAN). The number must come from GS1 — but the visual barcode you print on packaging can be generated free with our tool. Read our e-commerce barcode guide for the full process.
For Warehouse and Logistics Teams
Internal inventory does not need a GS1 number. Use Code 128 for SKUs, bin labels, asset tags, and shipping cartons. It encodes letters, numbers, and symbols in a compact form — perfect for cheap label printers and barcode scanners.
Standards Compliance
- Our generator validates check digits automatically (EAN, UPC, ITF-14).
- SVG output is mathematically precise — no anti-aliasing artifacts that confuse industrial scanners.
- Bar widths follow the official specifications for each format.
- Quiet zones (white margins) are calculated from the narrow bar width per ISO/IEC 15420.
Print Quality Tips
- Always download as SVG for label printing. Scaling stays sharp at any size.
- Use a thermal label printer at 203 DPI minimum (300 DPI for very small codes).
- Maintain at least 2 mm (~6 narrow bar widths) of quiet zone on each side.
- Print black-on-white. Avoid colored backgrounds — many industrial scanners use red lasers and read green/red as black.
- Test print runs of 100+ codes by sampling 5 with our scanner.
