Frequently Asked Questions
What is a Data Matrix code used for?
It is a compact 2D barcode used for product identification, asset tracking and industrial marking, where a small symbol must hold a reliable payload.
How is it different from a QR code?
Both are 2D codes, but Data Matrix symbols are typically smaller for the same amount of data and are the standard choice in industrial and electronics marking, while QR codes dominate consumer marketing.
Can I use the generated codes commercially?
Yes. The generator is free and the codes you create are yours to use in products, labels and documentation.
Any printing tips?
Keep the quiet zone (blank margin) around the symbol and a consistent module size so both phone cameras and industrial scanners read it reliably.
What is the minimum size for a scannable Data Matrix code?
Data Matrix codes stay scannable at sizes as small as 2 x 2 mm (about 0.08 inches) when printed at 600 dpi or higher on high-contrast surfaces. For reliable scanning, keep individual modules at least 0.25 mm wide and avoid printing below 300 dpi.
How much data can a Data Matrix code hold?
Depending on the symbol version, a Data Matrix stores up to 3,116 numeric characters, 2,335 alphanumeric characters, or roughly 1,556 bytes of binary data. Larger payloads require bigger symbols, so keep encoded text short if you need a very small code.
What file formats can I download my Data Matrix code in?
Export codes as PNG and SVG files. PNG works well for labels and documents at fixed resolutions, while SVG scales to any size without pixelation, making it ideal for print shops, laser engraving, and direct part marking workflows.
What does ECC200 error correction mean?
ECC200 is the standard error-correction scheme in every modern Data Matrix code. It uses Reed-Solomon coding to rebuild damaged modules and can typically restore up to 30% of the symbol, so codes stay readable after scratches, smudges, or worn laser etching.
What is a Data Matrix Code?
Data Matrix is a high-density 2D barcode capable of storing large amounts of data in a very small space. It uses the ECC200 error correction algorithm with powerful error recovery capabilities, allowing accurate reading even when partially damaged. It is widely used in electronics identification, medical device tracking, aerospace component management, and more.
