Developer Documentation
Comprehensive barcode reference for developers, supply chain professionals, and standards engineers. Covers barcode symbologies (1D linear, 2D matrix, stacked, composite), GS1 prefixes by country, check digit algorithms, industry regulations, print specifications, interactive tools, glossary, and in-depth guides. 15 languages supported.
- Barcode symbologies with full technical specs (character set, data length, quiet zones, X-dimension)
- Symbology families with evolution stories and family trees
- Barcode anatomy: components (start/stop characters, quiet zones, check digits, etc.)
- GS1 country prefixes — prefix-to-country lookup
- Check digit algorithms with step-by-step formulas (Modulo 10, Modulo 43, etc.)
- Industry-specific barcode regulations and compliance requirements
- Print specifications per symbology (X-dimension, quiet zones, magnification, grading)
- Barcode timeline — historical milestones from invention to modern standards
- Interactive tools: barcode generator, reader, check digit calculator, UPC converter, ISBN converter, size calculator
- Glossary of barcode terminology with cross-references
- In-depth guides organized by content series
- Side-by-side symbology comparisons
