In the fast-paced world of ecommerce, effective inventory management is crucial to the success of any business. One of the essential elements in modern inventory systems is the use of barcodes and Universal Product Codes (UPCs).
Though these terms are sometimes used interchangeably, they have distinct meanings and play different roles in inventory management. Understanding the differences between barcodes and UPCs, and how to use them properly, can significantly streamline inventory management, reduce errors, and enhance the customer experience.
Understanding Barcodes and UPCs
A barcode is a machine-readable image that contains data about the product it’s affixed to. Barcodes can come in different formats such as linear (1D) or 2D. Linear barcodes, like the ones commonly seen on retail products, consist of black and white lines of varying widths and are usually numeric. 2D barcodes, such as QR codes, can store more complex data including URLs or product descriptions.
A UPC (Universal Product Code), on the other hand, is a specific type of barcode widely used in retail cnd eCommerce. A UPC is a 12-digit number assigned to each product and represented by a barcode, which allows scanners to read the numbers easily. It is standardized and maintained by GS1, a global organization that ensures UPCs are unique and consistent worldwide.

Best Practices for Using Barcodes and UPCs in Inventory Management
Choose the Right Barcode Type
Depending on the nature of your products, you may need to decide between a 1D or 2D barcode. Most ecommerce businesses use 1D barcodes like UPC or EAN for standard product identification. If your business needs to store more complex information—such as batch numbers, expiration dates, or tracking details—consider using a 2D barcode like a QR code.
UPC for Retail Standardization
UPCs are essential if you’re selling products in retail or on major ecommerce platforms like Amazon, Walmart, or eBay. Since UPCs are globally recognized and standardized, they allow products to be easily identified across different retail environments. Ensure your business follows GS1 standards when obtaining UPCs to avoid duplicates or errors that could disrupt inventory processes.
“I love DCL’s use of lot capture. The serialized scanning at DCL is definitely best-in-class. The fact that they scan both the UPC and the lot number is critical. It means we are very comfortable and confident in our data for outbound orders—we know exactly what lots and which items are going out to customers. God forbid there’s a recall, even if there is, we have zero worry about tracing; we know we have great records.”
Efficient Scanning Systems
Whether you or your fulfillment provider are the ones handling lot tracking, an investment in quality barcode scanners is key to quick and accurate read barcodes. Modern scanning devices not only help with inventory management but also track sales, orders, and shipping details, all while reducing human error.
Your scanners will need to integrate with other systems, like your warehouse management system (WMS) or online retail platform (like Shopify). A big benefit of using scanning technology is real-time updates that ensure stock levels remain accurate, preventing overselling or stockouts.
Automate Inventory Updates
For better control and efficiency, integrate your barcoding system with inventory management software. This allows for real-time updates whenever an item is scanned during sales, returns, or cycle counts. Automating this process reduces manual input and ensures that your inventory data is always up-to-date.
Track Product Variants
If your business sells products in different sizes, colors, or batches, assigning unique UPCs or barcodes for each variant is essential. This prevents confusion during order fulfillment and ensures customers receive the correct item.
Scanning technology for tracking lots or batches of items is imperative for perishables or products with an expiration date. Proper tracking also helps with inventory forecasting and demand planning, leading to better stock management.
Plan for Scalability
As your ecommerce business grows, so does your inventory. Ensure that your barcode and UPC systems are scalable. You’ll want to be able to add new products and easily generate unique codes as needed without causing confusion in your inventory system. Scalable inventory systems also allow for easy integration with third-party logistics providers or new retail platforms.
Using Serialized Scanning for Lot Control
For businesses dealing with high-volume inventories or products that require stringent tracking, such as pharmaceuticals, electronics, or perishables, a modern system to track batches of products is important.
Here are the benefits of using a serialized barcode system for optimized lot control in inventory management.
- Enhanced Traceability: Serialized scanning assigns a unique identifier to each individual product or batch, allowing for precise tracking throughout the supply chain. This makes it easier to trace products back to specific lots or batches in case of recalls, quality issues, or regulatory compliance audits.
- Improved Inventory Accuracy: By scanning each item individually, businesses can maintain real-time, detailed records of stock levels. This reduces human error, prevents overselling, and ensures accurate inventory counts, which are critical for efficient order fulfillment.
- Better Quality Control: Serialized scanning helps ensure that the correct products are picked, packed, and shipped, minimizing the risk of incorrect shipments. Additionally, it supports First-In, First-Out (FIFO) practices, ensuring that older inventory is prioritized, reducing waste and expiration issues.
- Faster Problem Resolution: In the event of defects or issues, serialized scanning makes it easy to identify and isolate affected lots, enabling faster resolution and minimizing the impact on other products in the inventory.
Bottom Line
Barcodes and UPCs are indispensable tools in modern inventory management, especially for beauty brands, food and beverage companies, even consumer electronics companies wanting to wanting to thoroughly track products with personal data across the supply chain.
While a barcode is the general technology, UPCs are the global standard that ensures your products can be identified universally. By following best practices—such as choosing the right barcode type, ensuring label accuracy, and integrating automation—you can significantly enhance your eCommerce operations. When implemented correctly, these systems streamline your inventory processes, reduce errors, and improve customer satisfaction, helping your business grow more efficiently.
