How to Get a Barcode for Your Retail Product: Legal & Practical Steps

The Difference Between Generating and Registering a Barcode

Many people confuse the act of generating a barcode image with registering a barcode number. Our free tool allows you to generate the visual representation of a barcode (the black and white lines). However, if you want to sell a product in a retail store (like Walmart or Target) or on a major online marketplace (like Amazon), you cannot just make up a random number.

Step 1: Understand GS1

GS1 is the global non-profit organization that manages the barcode standard. They ensure that every product in the world has a unique identifier, known as a Global Trade Item Number (GTIN).

Step 2: Obtain a GS1 Company Prefix

To get official, globally recognized barcodes, you must apply for a GS1 Company Prefix from your local GS1 member organization (e.g., GS1 US, GS1 UK). This prefix identifies your company as the brand owner.

Note: There are third-party resellers who sell single barcode numbers, but major retailers often require barcodes directly from GS1 to verify brand ownership.

Step 3: Assign GTINs to Your Products

Once you have your prefix, you can assign unique GTINs to each of your products. Every variation of a product (size, color, flavor) requires its own unique GTIN.

Step 4: Generate the Barcode Image

After you have legally obtained your GTINs, you need to turn those numbers into scannable images. This is where a tool like our Free Barcode Generator comes in.

Select the appropriate format (usually EAN-13 or UPC).
Enter your 12 or 13-digit GTIN.

Step 5: Print and Apply

Finally, incorporate the downloaded barcode image into your product packaging design or print it onto adhesive labels. Ensure the barcode is printed clearly, with high contrast, and is large enough to be easily scanned by retail equipment.
