DataMatrix Generator API

DataMatrix is a compact two-dimensional matrix barcode defined by ISO/IEC 16022, capable of packing up to 2,335 alphanumeric characters into a symbol only a few millimeters wide. Its high data density and strong error correction under the ECC200 scheme make it the standard choice wherever printed real estate is scarce, from electronic component markings to direct laser etching on metal parts.

To generate a DataMatrix symbol, call the BarGen REST API with the payload text and target module size; the response returns an SVG for vector printing workflows or a PNG for raster placement. The service handles ECC200 encoding and symbol sizing automatically.

Data Matrix is a two-dimensional barcode consisting of black and white cells arranged in a square or rectangular pattern. Developed in 1989, it is widely used for marking small items and in industrial settings.

The code can store up to 2,335 alphanumeric characters or 3,116 numeric digits. It uses Reed-Solomon error correction, allowing up to 30% of the code to be damaged while still being readable.

Data Matrix is particularly popular for direct part marking (DPM)—permanently marking components with laser etching, dot peen, or chemical etching. The electronics, automotive, and aerospace industries use it extensively for component traceability.

The United States Electronic Industries Alliance (EIA) recommends Data Matrix for marking small electronic components. It is also used for postal marking, document management, and pharmaceutical packaging (often with GS1 identifiers).
