DataMatrix barcode generator
Direct part marking (DPM) on metal, plastic, and PCB components — laser-etched or dot-peened traceability codes in manufacturing and aerospace.
Character set
Full ASCII plus binary data, encoded in a square or rectangular ECC200 grid
Typical use
Direct part marking (DPM) on metal, plastic, and PCB components — laser-etched or dot-peened traceability codes in manufacturing and aerospace.
How it compares
DataMatrix's ECC200 error correction is specifically what makes it survive direct part marking — a printed 1D barcode can't tolerate the noise of an etched or peened surface the way ECC200's redundancy can.

- Select DataMatrix from the format dropdown
- Enter the value or serial number to encode
- Download the SVG or high-resolution PNG for your marking equipment's software
- Confirm read reliability with your specific marking hardware and surface material before a full production run
Common DataMatrix use cases
- Direct part marking on metal components via laser etching or dot peening
- PCB and electronics traceability codes that need to survive the manufacturing process itself, not just printing
- Aerospace and automotive component serialization, where marks must stay readable for the life of the part
- Asset tags on equipment exposed to wear, where a printed label would degrade faster than an etched or peened mark

FAQ
DataMatrix barcode questions
Same underlying ECC200 symbol and the same encoder — this page is written specifically for direct part marking: laser etching, dot peening, and industrial traceability. The general Data Matrix generator covers the broader case of labeling small parts and packaging.
The error-correction scheme used by modern DataMatrix symbols, standardized in ISO/IEC 16022. It's what makes DataMatrix viable for direct part marking — the symbol can still decode correctly even with a meaningful percentage of cells damaged or obscured, which matters when a code is etched into metal rather than printed on clean paper.
Yes — that's specifically what ECC200's error correction is built to tolerate. Real-world read reliability also depends on your marking equipment's dot contrast and consistency, which is a hardware and process question this generator doesn't control; the symbol data itself is standards-compliant either way.
It produces a standards-compliant DataMatrix as SVG or PNG. Most industrial marking software (laser, dot-peen, inkjet) accepts SVG or high-resolution PNG as source input — check your specific marking system's supported import formats.
