About these references
Each page is a fast table you can scan or filter: every barcode type the site supports with its capacity and uses, the GS1 prefix list, print sizes and quiet zones, GS1 Application Identifiers, how UPC and EAN relate, how book barcodes work and the colors and print choices that scan. Facts follow the primary sources, mainly the GS1 General Specifications, GS1's list of assigned prefixes and the ISO/IEC symbology standards, and each page links to the tool that does the job.
Looking for a tool rather than a table? The barcode tools generate, design, scan and check barcodes, all in your browser.
