Generate 2D tracking codes

Data Matrix is an dense 2D barcode standard used to mark small physical items like microchips or automotive components.

Set the data payload, adjust the scale in pixels per module, and set the foreground and background colors. The output renders to a canvas and can be downloaded as a PNG file.

Error correction and quiet zones

Modern Data Matrix codes use the ECC200 standard for Reed-Solomon error correction. This adds redundant mathematical data that allows scanners to reconstruct the payload even if the physical label is scratched or partially printed.

When printing Data Matrix codes for physical use, maintain a “quiet zone” (a blank margin surrounding the code) equal to at least one module width so hardware scanners can identify the finder pattern.

Frequently Asked Questions

Data Matrix is a 2D barcode standardized under ISO/IEC 16022. It stores data in a small physical footprint, making it common in manufacturing and logistics.

Data Matrix codes are physically smaller at the same data capacity. They are primarily used in industrial applications where scanning space is limited, whereas QR codes are optimized for smartphone scanning.

ECC200 is the modern standard for Data Matrix error correction. It uses Reed-Solomon algorithms to keep the barcode scannable even if up to 30% of its physical area is damaged.

A single symbol can hold up to 3,116 numbers or 2,335 alphanumeric characters. However, most real-world manufacturing applications use under 50 characters to keep the physical printed label as small as possible.

Yes. Unlike most 1D barcodes that only accept numbers and a few letters, Data Matrix supports raw binary payloads. This allows you to encode compressed strings or custom byte structures.
