A UPC barcode (Universal Product Code) is a 1D (one-dimensional) barcode widely used for tracking trade items and point-of-sale transactions in stores across the United States, Canada, and other regions. They are an essential part of modern retail, inventory management, and logistics, helping businesses track products, manage stock, and maintain accuracy throughout the supply chain.
In this guide, we will explore what information UPC barcode labels contain, their applications, and best practices for printing them.
What Information Do UPC Barcode Labels Contain?
UPC barcodes are available in two types: UPC-A and UPC-E. The UPC-A, the more common of the two, is 12 digits long and typically used for standard retail products. It provides detailed product information and is widely used across retail settings. In contrast, the UPC-E is a compressed 8-digit version, designed for smaller items or packaging where space is limited.
UPC barcode labels are typically applied to product packaging or labeling. They usually consist of the following key components:
● UPC Number
● Barcode Symbol
● Product Information
The barcode symbol is a graphic representation of the UPC number, enabling scanners to quickly and accurately read the product code.
If the barcode is poorly printed or blurred, it may cause scanning errors or failure to read, leading to delays in processing or incorrect product identification.
Depending on the application, UPC barcode labels may include additional product information, such as the product name, specifications, and price. For instance, e-commerce platforms like Amazon, eBay, and Shopify often use them as SKU labels or product barcodes to identify products and streamline the supply chain.
Applications of UPC Barcode Labels
UPC barcode labels are used across various industries for essential functions, including:
● Retail
● Inventory Management
● Supply Chain and Logistics
For businesses managing large volumes of stock like those in apparel, cosmetics, and consumer goods, UPC labels are essential for inventory tracking. They provide an easy way to monitor product movement, reduce errors, and ensure that shelves are stocked with the right products at the right time.
In retail, UPC barcodes speed up checkout by enabling quick product identification and price retrieval. Whether at a cashier or a self-checkout kiosk, the handheld scanner reads the product barcode, instantly retrieving pricing and product details to ensure a seamless transaction.
In the logistics industry, UPC barcodes track products as they move through different stages of the supply chain. From warehouse storage to shipping and delivery, these barcodes ensure accurate tracking and minimize the chances of lost or misplaced items.
Best Practices for Printing UPC Barcode Labels
Follow these best practices when printing UPC barcode labels to create clear, scannable codes.
1. Choose the Right Printer
Thermal transfer printers are ideal for long-lasting labels, especially for products that face harsh conditions such as wear and tear, extreme temperatures, outdoor exposure, or chemical corrosion. They use heat to transfer ink onto a label, providing durable, high-quality prints.
For short-term use or non-durable labeling needs, direct thermal printers are a more cost-effective option. These printers don’t require ink or ribbons but are best suited for indoor environments with controlled conditions.
All these barcode printers support on-demand printing and variable data printing, offering great flexibility.

2. Ensure Print Quality
A crisp and scannable barcode is important for smooth operations. Keep these factors in mind:
● High Resolution
For a barcode to be readable by scanners, it must have sufficient resolution. For clear, high-quality prints, a UPC barcode printer with a resolution of 300 DPI is recommended.
● Contrast
Make sure that the UPC barcode has high contrast against the background. Dark black barcodes on a light-colored background (usually white or yellow) provide the highest readability for scanners.
● Quiet Zone
Leave a "quiet zone" of blank space around the barcode. This is the area that ensures the scanner can clearly distinguish the barcode from surrounding text or graphics. A margin of at least 0.25 inches (6.35mm) is typically recommended.
3. Use Durable Labels
Select label materials that suit your product environment. For example, use synthetic labels for items exposed to moisture, grease, or outdoor elements. Paper labels are suitable for indoor products with shorter shelf lives.
4. Test the Barcodes
Before printing large batches, always test the barcodes with a scanner to ensure they are readable. This is a critical step to avoid printing errors and guarantee the barcodes scan smoothly in retail or warehouse environments.
Printing high-quality UPC barcode labels is essential for smooth retail transactions, effective inventory management, and reliable logistics. With these best practices, your barcode labeling process will not only streamline your operations but also support long-term success in a competitive marketplace.
