• Barcodes are all around us and can be found on just about anything we use. They’re used across industries like retail, grocery, healthcare, apparel, general merchandise, and many others to streamline information dissemination. The common barcode (known as a UPC/1D Barcode) consists of black-and-white lines that create a scannable image. Combined with these lines, the numbers, known as a UPC numbers, create the whole barcode. Each barcode is unique; it is assigned to a company and its specific product. In addition to providing unique identification, the barcode helps recall unsafe products like tainted food or even faulty airbags on cars. Barcodes play a massive role in making everything we do as consumers, workers, and business owners easier. Barcodes help provide proper inventory management and ordering and even maintain public safety for perishable items like food and vaccines. 

    There are many types of barcodes with different features used for unique applications. Businesses across nearly every industry worldwide should understand barcode standards, formatting, and function to effectively use them in their businesses or along their supply chains. Efficiency and accuracy in inventory management and supply chain tracing, and serving customers at point-of-sale (POS) or patients at point-of-care (POC) can all be improved with barcode reading and scanning.

How Do Barcodes Work?  

Barcodes work by encoding numbers into a pattern of vertical bars, dots, or boxes. Linear, or one-dimensional (1D), barcodes use a single row of vertical bars arranged in a specific pattern, while two-dimensional (2D) barcodes (often referenced as QR Codes) are made of a matrix of dots and boxes that can be scanned omnidirectionally—or in two dimensions—to display information. It can seem impossible to decode information in a barcode, but laser scanners and image scanners alike can quickly "read" the information by either sending a laser across the barcode or capturing an image of it. Image scanners and readers capture an image of the barcode then translate the pattern into alphanumeric information. Because of this, all barcodes must have a certain amount of contrast between the code’s pattern and background so the light can reflect properly. This is why barcodes are often printed in black against a white background. If a barcode doesn’t have sufficient contrast with its background, the risk of a read error is increased. To ensure readability, contrast and reflectance must be considered just like in 1D barcodes. Readability is checked during barcode verification tests.


History of the Barcode

The barcode has become a fixture in everyday life, but it hasn’t always been that way. Norman Joseph Woodland and Bernard Silver invented the barcode in 1949 to streamline the customer experience at checkout and improve inventory management. The barcode structure was based on Morse code, with thick and thin bars arranged in specific patterns to represent numbers zero through nine. The Universal Product Code (UPC) was fully adopted for standard use in 1973, and the first barcode was scanned on a 10-pack of Wrigley’s Juicy Fruit gum in an Ohio supermarket. For now, the UPC remains the standard for retail products.

In 1987, the 2D barcode was invented. The first 2D barcode was called “Code 49” and had the appearance of a box of layered linear barcodes. Since then, the 2D barcode has evolved from Code 49 to the QR Code, GS1 DataMatrix, and many others that can hold more information than linear codes.

Where Does GS1 US Fit Into the Timeline

GS1 US® is a global standards organization that was formed in 1974 when grocery stores moved to create the Uniform Code Council (UCC) to ensure barcodes were consistent across the industry. GS1 US was established to help organizations uniquely identify products, assets, locations, and more with barcodes that can be used globally. The ability to track your barcodes anywhere in the world can help you more easily manage your supply chain so you know where products are each step of the way until they’re in your customers’ hands. In addition to providing barcode services, GS1 US is also an expert across various industry standards, so our team can help ensure your barcodes meet requirements.

The Present and Future of the Barcode With GS1 US 

Today, GS1 US sets the standards for barcodes in North America that work seamlessly with additional international standards. We’ve established these standards to prevent duplication of product, location, and asset identification codes. With many linear and 2D barcode options, our mission is to continue providing a system of standards across more than 25 industries. In response to the Food Safety Modernization Act (FSMA) and Drug Supply Chain Security Act (DSCSA), GS1 US sees opportunities to leverage 2D barcodes at both point-of-sale and at point-of-care. This shift to 2D barcodes will allow organizations to:

  • Improve inventory management 
  • Enhance recall readiness 
  • Provide greater sustainability and ethical sourcing 
  • Offer better authentication 
  • Create greater brand trust
