How to Choose the Right Barcode Format

If you are launching a new product, formatting your packaging correctly is crucial. Retailers and fulfillment centers (like Amazon FBA) have strict requirements for scanning. Our free barcode generator supports the three most common formats used globally:

• UPC-A (Universal Product Code): This is the standard retail barcode used almost exclusively in the United States and Canada. If you are selling a physical product in an American grocery store, boutique, or on US Amazon, you need a UPC. It requires exactly 12 numeric digits.
• EAN-13 (European Article Number): This is the global standard used outside of North America. If you are selling products internationally, the EAN-13 (which requires 13 numeric digits) is your go-to format.
• Code 128: Unlike UPC and EAN, Code 128 is a high-density alphanumeric barcode. This means you can use letters, numbers, and symbols. It is widely used in B2B shipping, logistics, warehouse management, and internal inventory tracking.

Do I Need to Buy a Barcode?

Our upc barcode maker generates the scannable image for free. However, if you are selling in major retail chains (like Walmart or Target), they require your numbers to be officially registered with GS1 (Global Standards 1) to prove your brand owns them. You purchase the prefix from GS1, and then you can use our tool to instantly generate the scannable graphic for your packaging designer.

Taking Your Product Packaging to the Next Level

A standard 1D barcode is great for the cashier to scan the price, but it does absolutely nothing for your customer.

Modern e-commerce brands are dedicating space on their labels for dual-scanning. While the UPC sits on the bottom of the box for inventory, they place a prominent QR code on the back. When customers scan it, it takes them to an unboxing video, a warranty registration page, or an exclusive discount code for their next purchase.
