What Aztec Code is
Aztec Code is a square 2D matrix symbol built around a bullseye finder pattern at its center, standardized as ISO/IEC 24778.

Valid input
Aztec Code encodes numeric, text, and binary byte data with Reed-Solomon error correction; bwip-js rejects data that exceeds the symbol's encodable capacity for the chosen size.
Key options
Supported bwip-js options include eclevel (error-correction percentage), layers (fixed layer count), and format ("full", "compact", or "rune") for smaller payloads.
Output and printing
Export PNG for digital use or SVG for crisp print; unlike many symbologies, Aztec Code needs no surrounding quiet zone because its finder pattern is self-contained.
Common uses
Aztec Code for tickets, passes, and compact high-density labels, most visibly as the format many airlines use for e-boarding passes.
Example
See the live preview above, seeded with a bwip-js-verified valid value.
Size guidance
Aztec Code has no mandatory quiet zone, letting it print smaller and closer to other marks than most linear or matrix symbologies.
Troubleshooting
If generation fails, the data likely exceeds capacity for the selected layers/format setting; try a higher layers value or the full (non-compact) form.

FAQ
Does Aztec Code need a white border?
No -- its bullseye finder pattern lets scanners locate it without a dedicated quiet zone, per ISO/IEC 24778.
