Markings of the future: How GS1 DataMatrix and DPM are setting standards
Digital and flexible: Supply chain management with GS1 DataMatrix and IoT
Progressive globalization, rising quality demands, and stricter legal requirements mean that companies must make their supply chains increasingly transparent. In this context, the marking of products, parts, and components with the GS1 DataMatrix in combination with Direct Part Marking (DPM) has established itself as an extremely reliable solution. Unlike conventional one-dimensional barcodes, the GS1 DataMatrix can store significant amounts of data in a very small space and, thanks to robust marking methods, remains readable for extended periods even in demanding environments. This future-oriented approach not only enables seamless traceability in the event of recalls or maintenance work but also creates the foundation for enhanced quality management and seamless integration into digital systems. Companies in industries such as automotive, aerospace, electronics manufacturing, medical technology, and pharmaceuticals benefit equally from this standard, which combines flexibility, security, and efficiency.
Thanks to internationally recognized GS1 standards, the collected information can be easily integrated into ERP systems, supply chain management solutions, and cloud-based track-and-trace platforms. This creates a comprehensive network in which every single part can be uniquely identified throughout its entire lifecycle. This offers advantages not only in quality assurance and service but also enables better customer loyalty and compliance with regulatory requirements. GS1 DataMatrix and DPM allow the physical world to be linked with the digital world, which is becoming increasingly important in the context of Industry 4.0 and the Internet of Things (IoT). Companies can thus access data in real time, optimize processes, and gain a competitive edge.

What is the GS1 DataMatrix and what advantages does it offer compared to one-dimensional barcodes?
The GS1 DataMatrix is a two-dimensional code that can store more information in a smaller area compared to conventional barcodes (e.g., EAN, UPC). This makes it particularly suitable for products, components, and individual parts. Key advantages include:
- High data density: Extensive information such as serial numbers, batch numbers or quality data can be stored in the smallest space.
- Durability: Even under adverse conditions (e.g. extreme temperatures, chemicals), a cleanly applied code often remains readable for years.
- Fault tolerance: Thanks to integrated error correction methods (e.g., Reed-Solomon), even damaged codes can still be read.
- Future-proof: GS1 DataMatrix is an internationally recognized standard that can be integrated into modern IT systems and supply chain solutions.
What does Direct Part Marking (DPM) mean and why is it so important?
Direct Part Marking (DPM) describes the direct and permanent application of a mark directly onto the product itself, instead of using a label or sticker. This is particularly important because:
- Durability: The marking remains intact even under heavy use or aging.
- Safety: A "removable" label can get lost; with DPM, the code becomes an integral part of the component.
- Transparency: Complete labeling enables unambiguous identification of parts throughout their entire life cycle.
What role does code longevity play in practice?
Durability is crucial for reliably identifying products even after years or decades. This is important for:
- Recall campaigns: Affected components can be clearly traced.
- Maintenance and repair: Even older components can be easily identified.
- Quality assurance: Long-term data on production and usage facilitate the analysis of defects.
A production manager from the automotive industry says: "With GS1 DataMatrix and DPM, we can still trace exactly when and where a part was manufactured, even after many years, in order to be able to react appropriately in the event of a defect."
Why is the high data density of the GS1 DataMatrix so relevant?
Large amounts of data can be stored in a very small space. This is particularly advantageous in industries with very small components, such as electronics manufacturing or medical technology. Here, information such as serial number, production batch, quality parameters, or safety certificates can be contained in a tiny code – for example, on a chip package or a screw.
How does integrated error correction work and what are its advantages?
The GS1 DataMatrix, for example, uses Reed-Solomon algorithms for error correction. This allows parts of the code (up to a third of the area) to be corrupted without data loss. This is particularly important for industries where products are exposed to extreme conditions, such as aerospace or military.
An engineer from the aerospace industry emphasizes: “We work with parts that are exposed to extreme temperature fluctuations, vibrations, and chemical stresses. The GS1 DataMatrix ensures that we can still access the coded information even after a long time.”
Which materials can be used for DPM?
The flexibility of the marking methods allows the GS1 DataMatrix code to be applied to a wide variety of materials:
- metal
- plastic
- Glass
- ceramics
- Wood
Depending on the substrate, different methods are used, such as laser engraving, etching, or dot peening. This allows for the unambiguous identification of almost all parts in industries with highly heterogeneous component groups.
In which industries is DPM with GS1 DataMatrix already standard?
DPM and GS1 DataMatrix are used across various industries, for example:
- Automotive industry: Identification of each individual part in complex supply chains.
- Aerospace: Marking of critical parts such as turbine blades or landing gear components.
- Electronics manufacturing: Miniaturized components for comprehensive traceability.
- Medical technology and healthcare: Unambiguous identification of implants, instruments or laboratory samples.
- Pharmaceutical industry: Counterfeit-proof labeling of medicines.
What challenges can arise during Direct Part Marking?
Although DPM offers many advantages, it also presents challenges:
- Technical expertise: The correct procedure must be selected depending on the material.
- Marking quality: To ensure long-lasting readability, quality standards (e.g., at least 1.5 according to ISO/IEC 15415) should be followed.
- Verification: Modern code verifiers check contrast, modulation, and quiet zone to ensure that the code remains readable throughout the entire product lifecycle.
Why are special reading devices necessary?
Conventional scanners quickly reach their limits with directly marked codes, as DPM codes:
- Not as high-contrast as printed labels.
- Often applied to curved, rough, or reflective surfaces.
Special DPM scanners feature optimized lighting and image processing technologies to reliably read even hard-to-see markings.
How does the GS1 DataMatrix contribute to traceability and quality assurance?
The GS1 DataMatrix allows structured data such as serial numbers, batch information, or production data to be captured in IT systems. Seamless integration with ERP and supply chain management solutions enables:
- Real-time tracking: Companies know at all times where a product is located in the supply chain.
- Efficient traceability: In case of problems, affected parts can be precisely identified.
- Comprehensive quality assurance: Data on manufacturing and life cycles help with error analysis and process optimization.
What is the significance of the GS1 DataMatrix in highly regulated industries?
In industries with strict regulations – such as pharmaceuticals, medical technology, or aviation – complete traceability is legally required. The GS1 DataMatrix offers:
- Anti-counterfeiting measures: Clear labeling of medications makes product counterfeiting more difficult.
- Regulatory compliance: The traceability of implants or instruments increases patient safety and fulfills legal requirements.
- Complete documentation: Clear identification of each component simplifies recalls and root cause analysis in case of malfunctions.
How is the technology surrounding DPM and GS1 DataMatrix developing further?
Research and development focuses on the following points:
- More precise marking methods: Improved laser and etching techniques for consistent and error-free codes.
- Optimized scanners: New lighting concepts and image processing for even more robust reading results.
- Automated processes: Robots can apply markings and perform quality checks simultaneously, increasing reliability.
