AIAG labels are a mandatory element of the modern automotive industry and its associated supply chains. Whether you supply components to OEM plants, operate a logistics center, or integrate a WMS/ERP system, you'll sooner or later encounter AIAG labeling requirements and the challenge of reliably scanning them.
Below we will discuss what AIAG labels are, how they are designed, what barcodes are used on them, and what to pay attention to when implementing a scanning system based on the
VintaSoft Barcode .NET SDK.
What are AIAG labels and why are they needed?
AIAG (Automotive Industry Action Group) is an association of automakers and their suppliers that develops industry standards, including those for labeling and logistics. The goal of these standards is to make the exchange of goods and data between supply chain participants predictable and automated.
The AIAG label is the standard logistics label for parts used in the automotive industry.
AIAG label:
- sets a uniform format for displaying key data about cargo;
- determines the structure of fields and their arrangement in zones;
- regulates the use of barcodes for automatic reading.
This means that manufacturers, logistics operators, and warehouses don't have to waste time adapting to each supplier's unique format: the barcode scanner and software know where to find the necessary information and how to interpret it.
AIAG label structure
The specific appearance of the label may vary depending on the OEM, but the general principles remain the same. Typically, the AIAG label is divided into zones, each containing a specific type of information—in text and/or as a barcode.
On such a label you will almost always find:
- Supplier ID. Company name and supplier code. In the barcode, the supplier code can be encoded as a separate field.
- Part Number. The primary identifier for a part, agreed upon with the OEM. Often duplicated in large text and in a one-dimensional barcode (Code 128 or Code 39).
- Part description. A short text that facilitates visual inspection: part type, model, etc.
- Quantity. How many units of product are in a box/pallet. Can be encoded in a separate barcode.
- Batch/lot number, serial number. Important for traceability, product complaints, and recalls. Often represented as a two-dimensional barcode (e.g., DataMatrix).
- Packaging/container number. A unique identifier for a specific packaging unit (shipping container code). It is used as one of the key barcodes for tracking.
What types of barcodes are used on AIAG labels?
Although AIAG standards allow for variability, in practice the most commonly used barcodes are Code39, Code128, and DataMatrix:
- Code39. One of the first and most widely used formats in industry. Simple and fairly reliable, but not the most information-dense.
- Code128. More compact and flexible in character encoding. Well suited for encoding long part numbers and complex identifiers.
- DataMatrix A very compact and damage-resistant barcode. Often used to encode serial numbers, batches, and additional attributes.
When developing a scanning system, it is important that the SDK be able to reliably recognize both 1D and 2D barcodes, as well as quickly process images with multiple barcodes simultaneously - this is what typical AIAG labels look like.
Key tasks when scanning AIAG labels
Scanning a barcode doesn't necessarily mean processing a label correctly. Real-world projects typically involve solving a whole range of problems:
- Detect all barcodes on the label
One sticker may contain several different barcodes.
It is necessary to find them all, determine the type of each barcode and display the result in a convenient format.
- Data interpretation
Each field (part number, quantity, batch, etc.) can have its own prefix, standard or format.
The application must "understand" which of the scanned barcodes belongs to which label field.
- Working in difficult conditions
The sticker may be wrinkled, partially covered with tape, or printed with low contrast.
Barcode scanning can be performed from different distances, at an angle, on a moving conveyor.
- Integration with existing systems
The results of label scanning must be transferred to a WMS, MES, ERP or specialized acceptance system.
Often these are .NET applications (desktop, web applications, data collection terminals).
- Performance
In logistics and manufacturing, speed is critical: a single camera can scan thousands of labels per hour.
The SDK must work efficiently with image streams and not become a system bottleneck.
Given these requirements, when choosing a barcode recognition tool, it is important not only to support the required barcode types, but also to ensure ease of integration, performance, and customization flexibility.
Why is it convenient to use VintaSoft Barcode .NET SDK for scanning AIAG labels?
VintaSoft Barcode .NET SDK is a .NET SDK that solves the problem of barcode recognition in industrial and business applications.
Key features of the SDK that are important specifically for working with AIAG labels:
- Support for major barcode types
One-dimensional: Code39, Code128 and other common formats.
Two-dimensional: DataMatrix, QR Code, etc.
This covers the typical set of codes used on AIAG labels from different OEMs.
- Recognizing multiple barcodes in one image
The SDK can find and decode multiple barcodes at once on a single label photo.
This is critical for AIAG labels, where there are multiple barcodes with different types of data on one sheet.
- Flexible integration into .NET applications
The library can be used in desktop, server, and web solutions based on .NET.
Suitable for implementation:
- acceptance and shipment at the warehouse;
- packaging line terminals;
- internal quality control tools.
- Working with images and video streams
Scanning is possible both from ready-made images (JPG, PNG, TIFF, etc.) and in real time from a camera.
This gives you freedom in choosing equipment: from an industrial camera on a conveyor belt to a regular webcam or a tablet's built-in camera.
- Quality and performance settings
It is possible to change the barcode recognition parameters, balancing between speed and accuracy.
It is possible to limit the barcode search to only the required barcode types (for example, only Code128 and DataMatrix), which speeds up the process and reduces the number of false positives.
This makes the
VintaSoft Barcode .NET SDK well suited for projects that require standardized and reliable scanning of AIAG labels and the integration of the results into existing .NET systems.
Practical tips for working with AIAG labels
To ensure the AIAG label scanning system operates reliably, please note the following:
- Print quality
Use thermal transfer or thermal printers designed for barcodes.
Pay attention to contrast; do not print barcodes on backgrounds with patterns or colored stripes.
- Label size and information density
Don't try to "fit everything" into a format that is too small - it makes scanning difficult.
Use reasonable module sizes (bars, squares) for DataMatrix and one-dimensional barcodes.
- Label location
The label must be affixed to a relatively flat surface.
Try to avoid folds at the junction of boxes and pallets.
- Selecting equipment and cameras
Test different shooting distances and angles.
For conveyor lines, it is worth considering fixed cameras with illumination.
- Setting up the VintaSoft Barcode .NET SDK
Limit the set of barcode types to those actually used in your project - this will improve speed and accuracy.
Adjust noise levels, contrast, and other image processing settings as needed.
Summary
AIAG labels are standardized logistics labels for the automotive industry, containing a set of key data about the supplied part: supplier ID, part number, quantity, batches, serial numbers, and other fields. This data is duplicated as one-dimensional (Code39, Code128) and two-dimensional (DataMatrix, etc.) barcodes, enabling automated receiving and shipping.
VintaSoft Barcode .NET SDK provides all the necessary tools for implementing such a system in .NET applications: support for popular 1D/2D barcodes, image and video stream processing, flexible settings, and convenient integration. By building a process based on this SDK, you can reliably scan AIAG labels, structure the resulting data, and seamlessly integrate it into your existing enterprise infrastructure.
