(EAN-13, Code 128 & More)

Warehouse scanning

Still manually entering SKUs? Typing SKU numbers by hand during inventory checks or order fulfillment wastes time and makes errors more likely. A SKU barcode generator solves that. It turns your SKUs into clean, scannable barcodes, eliminating that friction. Scan and go. That's the difference.

For online sellers, warehouse managers, or startup brands, this can mean faster checkouts, fewer manual errors, and streamlined logistics. And the best part? You can do it all online, for free.

What Is a SKU and Can a SKU Be a Barcode?

A SKU (Stock Keeping Unit) is your product’s internal DNA. It’s a unique code of letters and numbers you create to track vital details like type, size, and color. Think of it as the ultimate shorthand for keeping your inventory straight.

Can a SKU be a barcode? Absolutely. In fact, it should be.

On its own, a SKU is just text and numbers. But the right generator transforms it into a powerful, scannable barcode like a Code 128, EAN-13, or UPC-A. Suddenly, that simple code is machine-readable, instantly linking a quick scan to all your critical product data.

For countless pros, from Amazon sellers to warehouse crews, slapping barcodes on SKUs is their bread and butter.

Here’s where you'll see it in action:

What Barcode Format Should I Use for My SKU?

The right barcode format depends on where and how you plan to use it. Here are a few common formats and their ideal use cases:

Code 128

Flexible and compact. It supports letters, numbers, and symbols. Ideal for internal SKU systems, warehouse management, and retail.

EAN-13

Standard in global retail. Works well if your SKU is a 12- or 13-digit numeric code. Required by many large retailers.

UPC-A

Popular in North America. Numeric-only, 12 digits. Works best for products already standardized for mass retail.

QR Code

Good if you want to store more than just the SKU, like a product URL, serial number, or custom data.

Choosing the right format upfront saves time later. Make sure the barcode you create aligns with the scanner or platform you’ll use.

Best SKU Barcode Generator for Warehouse Teams, Retailers, and Startups

Generating a barcode from your SKU is easier than most people think. The key is to choose a barcode maker that creates professional, compliant barcodes— without asking you to sign up or install anything.

Plenty of free SKU barcode generators exist online, but many limit your access. Some hide basic features behind paywalls. Others slap watermarks on your output. Worse, a few ask for email sign-ups just to download a single barcode.

FAQs About SKU Barcode Generation

Can I print these barcodes at home?

Yes. Any standard inkjet or laser printer can print barcode images clearly enough for scanning.

Do I need to register or pay?

No. Our barcode generator is 100% free and requires no login.

Can I convert a product name into a barcode?

Yes, though it's better to assign a unique SKU to each product first. Then convert that SKU into a barcode.

Are these barcodes GS1-compliant?

If you're creating EAN-13 or UPC-A barcodes for retail use, you’ll need a GS1 prefix issued by GS1 US or your local GS1 organization. Most major retailers require GS1-registered barcodes for products sold in stores.
