If you're looking to sell products either online or in retail stores, then you'll be in need of a UPC. That is the barcode that identifies your product anywhere on Earth, and most importantly, it will help retailers and suppliers-not to mention eCommerce platforms-manage inventory much easier. All too often, new business owners wonder: how do I create a UPC?
In this guide, we are going to walk you through everything you need to know, from what a UPC is and how you can correctly generate and register it for your products.
What is a UPC?
UPC stands for Universal Product Code, a unique identifier assigned to products for sale at retail. It consists of a 12-digit number and a barcode symbol which can be scanned at the point of sale.
Each UPC code is assigned to a specific product, size, or variation to avoid confusion between similar items on the market. This system is recognized globally and maintained by GS1, a nonprofit in charge of setting the standards for barcodes.
Why You Need a UPC
Before digging into how to create a UPC, it's good to know why it matters. A UPC allows:
Ensure the retailers can scan and track your products with ease.
E-commerce websites like Amazon or Walmart for product identity verification
Inventory systems to manage stock levels automatically
Accurate reporting, analytics, and supply chain visibility
Without a UPC, your product might not be accepted on major e-commerce or retail websites.
How Do I Create a UPC? Step-by-Step Guide
Creating a UPC is simpler than it seems. Follow these easy steps:
- Join GS1
First, you need to log in to the official GS1 website at gs1.org and apply for a company prefix. It identifies your business globally and serves as the root of your UPC codes.
Step 2: Obtain a Company Prefix
Once registered, GS1 assigns you a unique company prefix that is representative of your brand in all UPCs you will be creating. The length of this prefix depends on the number of products you plan to label.
Step 3: Assign Product Numbers
Now, give each product or product variant-let's say color or size-a unique product number. Take your company prefix and combine it with the product number to complete the first 11 digits of the UPC.
Step 4: Compute the Check Digit
The 12th digit of a UPC is called a check digit — it's automatically calculated by a mathematical formula to verify that the code is valid. Many barcode generation tools can do this for you.
Step 5: Generate the Barcode Image
Take your 12-digit UPC and, with the help of a barcode generation tool like the recommended software of GS1 or third-party websites, transform your number into a scannable barcode image. You can then print it on your product labels or packaging.
Step 6: Test and Verify
Finally, use a scanner to check that the barcode is readable and correctly formatted before mass printing.
UPC Creation: Is It Possible Without GS1?
Some online sellers purchase barcodes from third-party resellers at a lower cost. However, these may not always be accepted by platforms like Amazon or Walmart, as they require GS1-verified codes.
For long-term brand growth and credibility, it's best to get your UPC directly from GS1.

UPC Creation: Some of the Common Mistakes to Avoid

Always make sure your UPC is legitimate and assigned under the name of your business in the GS1 database.
Conclusion
Knowing how to create a UPC is critical for any brand looking to expand into retail or e-commerce. A GS1-certified UPC not only simplifies the inventory but also helps build trust with the distributors and customers.
For a start-up or established manufacturer, taking the required time to generate and register the UPCs correctly will ensure that your products are ready to be recognized globally as well as have smooth retail operations.
