Tips for Printing

Size Matters

Barcodes should be at least 1 inch wide for reliable scanning. Larger is better for warehouse use.

Contrast is Key

Print black bars on white labels. Avoid colored backgrounds that reduce scanner accuracy.

Test First

Always test scan your printed barcodes before applying them to all products.

Protect Your Labels

Use laminated labels or protective overlays for products exposed to moisture or handling.

Frequently Asked Questions

Do I need to buy UPC codes?

Yes, if you're selling retail products in stores. UPC codes are assigned by GS1, the global standards organization. You'll need to register with GS1 to get legitimate UPC codes for your products.

For internal use only (warehouse tracking, inventory management), you can use Code 128 with your own SKU system.

Can I use these barcodes for Amazon or Shopify?

Amazon: Requires official UPC/EAN codes from GS1, or you can use Amazon's FNSKU labels for FBA products
Shopify: SKU barcodes are for your internal use. For retail sales, you'll need official UPC/EAN codes

What's the difference between 1D and 2D barcodes?

This tool generates 1D (linear) barcodes. They're the traditional horizontal lines you see on most products. 2D barcodes (like QR codes) store more data in a square pattern. For product identification, 1D barcodes are still the standard.
