MaxiCode Generator API

MaxiCode is a fixed-size two-dimensional symbology standardized as ISO/IEC 16023, developed by UPS to sort packages at high speed on conveyor lines. Unlike most 2D formats, every MaxiCode symbol is exactly the same physical size, a grid of hexagonal dots surrounding a bullseye finder pattern, which lets fixed-focus scanners read it reliably at any rotation as packages pass beneath them.

BarGen generates a MaxiCode symbol from a structured data string via the REST API, returning SVG or PNG output sized to the fixed MaxiCode dimensions for direct placement on shipping labels.

MaxiCode is a 2D barcode consisting of a central bullseye finder pattern surrounded by a hexagonal grid of modules. Developed by UPS in 1992, it was designed specifically for high-speed package sorting.

The code has a fixed size of 1 inch square and can encode up to 93 alphanumeric characters. It uses Reed-Solomon error correction and can withstand up to 8% damage while remaining readable.

MaxiCode's unique hexagonal pattern allows it to be read from any orientation and at high speeds—critical for automated package sorting conveyor systems. UPS uses it as their primary package tracking barcode.

Beyond package tracking, MaxiCode is used in automated industrial systems and anywhere high-speed omni-directional scanning is required. It became an international standard (ISO/IEC 16023) in 2000.
