How do I know which bar code symbology to use?
Each bar code symbology has an intended usage or purpose. You must evaluate your product’s packaging and its assigned Global Trade Identification Number (GTIN) in order to choose the appropriate symbology based on the intended purpose of the bar code. For more information and examples of the correct symbology structures to use, click here to see our GTIN Example. Additionally, a more detailed explanation on building the GTINs for each packaging hierarchy, see the power point presentation on GTIN Fundamentals (PowerPoint Presentation).
