Need to mark small parts, curved surfaces, or components where a standard barcode won’t fit? The GS1 DataMatrix is the compact 2D barcode designed for exactly that — packing detailed product data into the tiniest of spaces.
GS1 DataMatrix is a two-dimensional barcode that encodes a large amount of information in a very small footprint. It's ideal for direct part marking and tracking high-value or regulated items where traceability and precision matter.
The GS1 DataMatrix is printed as a grid of small squares or dots, either square or rectangular in shape.
Ideal for marking tiny or irregular-shaped parts, such as circuit boards, microchips, and electronic assemblies, where a traditional barcode simply won’t fit. It allows manufacturers to encode vital tracking information without compromising on space.
Widely adopted in healthcare and pharmaceuticals, GS1 DataMatrix enables direct part marking on surgical implants, instruments, and devices. This supports asset tracking, reduces the risk of counterfeiting, and improves patient safety through enhanced traceability.
In high-stakes industries like automotive and aerospace, where part identification must withstand extreme conditions, DataMatrix is directly engraved onto metal components. Fun fact: NASA was one of the first to use DataMatrix in the 1980s to label rocket parts because the codes wouldn't peel or fade.
GS1 DataMatrix can hold variable data like batch codes, use-by dates, and product origin, helping reduce scan time and ensuring only affected packs are recalled — not an entire batch. This makes it valuable for fresh produce and perishable goods where precision matters.
GS1 DataMatrix follows global GS1 standards, making it suitable for regulated supply chains. It includes a Function 1 Symbol Character (FNC1) at the start of the code to identify it as GS1-compliant — a key difference from generic or unregulated DataMatrix codes.
DataMatrix is widely used in sectors that require precise part marking and traceability, such as:
In fact, global healthcare authorities have identified GS1 DataMatrix as their long-term preferred barcode.
In certain cases, yes. For example, some Australian supermarkets are replacing EAN-13 barcodes with GS1 DataMatrix for meat and fresh produce to encode more product data and reduce scan errors.
You’ll need a camera-based or 2D barcode scanner. Traditional 1D laser scanners cannot read GS1 DataMatrix codes. Many retailers are now upgrading their POS systems to support 2D barcode reading. GS1 NZ is working with retailers and product manufacturers to ensure all retail point-of-sale systems in New Zealand can scan 2D barcodes by the end of 2027.
The symbol size depends on the amount of data encoded:
Choose the format based on the available space and required data capacity.
The smallest GS1 DataMatrix symbol starts at 10×10 modules, making it ideal for very small parts or limited surface areas.
GS1 DataMatrix uses Application Identifiers (AIs) to structure the data within the code.
Common AIs include:
You can view the full list on GS1 New Zealand’s website.
Laser marking is a popular method due to its permanence and ability to mark diverse materials like plastic, metal, and glass. Other options include:
Choose the method based on the surface type and product durability needs.
