Aztec is a two-dimensional or matrix code that can encode up to 2,000 characters. The code is easily recognized by the central "bulls eye". When decoding an Aztec symbol the scanner works its way from the center outwards. As a consequence Aztec codes can be used without a quiet zone around the barcode, resulting in the lowest possible space requirements of all 2D codes.

Aztec Specifications

Aztec is standardized. The relevant standard is ISO/IEC 24778-2008 and can be obtained from ISO.

This code has been verified to scan properly on Mac and Windows PCs. Check the settings of your scanner if the scan result is different or if the code doesn't scan at all.

Common problems when scanning Aztec with non-ASCII data:
  • The Aztec symbology is deactivated in the scanner
  • The keyboard layout setting of the scanner does not match the locale setting in your computer
