Every Symbology

Fifteen symbologies, one fluent builder each. Two-dimensional matrices carry more data in less space; linear barcodes scan on older hardware and print narrower.

Every figure below is the symbol its page documents, generated from the code that page shows.

Choosing one

• Codabar Codabar, also known as NW-7, is a simple numeric-heavy barcode used by libraries, blood banks,
• Code 128 Dense linear barcode over the full 7-bit ASCII range. Automatically picks code sets to keep
• Code 39 Uppercase-only linear barcode, one of the oldest and simplest symbologies still in common
• Code 93 Higher-density successor to Code 39. It supports the same visible character set used here and
• Data Matrix Compact square 2D symbol, ECC200 single-region only (10x10 to 26x26 modules). Reed-Solomon
• EAN-13 The retail barcode printed on nearly every packaged product worldwide. Give it 12 digits and
• EAN-8 Compact retail barcode for small products. Give it 7 digits and the check digit is computed;
• GS1 DataMatrix GS1 DataMatrix uses the same GS1 input contract as Gs1128, then renders an ECC200-style
• GS1-128 Code 128 profile for GS1 element strings. It inserts FNC1 at the start, adds group separators
• ISBN Book identifiers, rendered as their EAN-13 "bookland" barcode. Accepts either format:
• ITF-14 Logistics barcode for GTIN-14 shipping containers. It is built on Interleaved 2 of 5 and
• Interleaved 2 of 5 Dense numeric-only barcode for warehouse, industrial, and distribution workflows. It encodes
• QR Code The most recognizable 2D symbol. Automatically picks numeric, alphanumeric, or byte mode,
• UPC-A Retail barcode used heavily in North America. Give it 11 digits and the check digit is
• UPC-E Zero-compressed UPC for small packaging. It accepts the 6-digit payload, 7 digits with number
