Batch number
Whether it’s a product recall at the supermarket or quality control in the warehouse, a small code on the packaging makes all the difference. Find out how this alphanumeric key ensures complete traceability throughout the supply chain.
What is a batch number?
The batch number is a unique alphanumeric code that is assigned to a specific production quantity and enables all products manufactured or packaged under identical conditions to be traced seamlessly throughout the entire supply chain. The term “batch” describes the total quantity of an item produced in a continuous production process.
Composition and structure of a batch number
A batch number usually consists of a combination of letters and numbers. The exact structure varies depending on the manufacturer and industry. The batch number often contains information about the production site, the date of manufacture, and a serial number for unique identification.
An example of a typical batch number would be “NW-20260215-047.” Here, “NW” stands for the production location, ‘20260215’ for the date of manufacture, and “047” for the sequential number of the batch on that day.
Batch number, lot number, and batch number
In practice, different terms are used synonymously. The lot number, batch number, and LOT number refer to the same principle as the batch number. All these terms stand for the unique identification of a production unit. The term “batch” has its origins in French and has become established as the standard term in German-speaking countries.
Where can you find the batch number on a product?
The batch number can be found on almost every packaged product. How and where it is placed depends on the type of product and the industry.
Batch number on packaging and labels
On physical packaging, the batch number is often located near the best-before date or the barcode. On bottles and jars, it is often printed on the lid or label. On cardboard packaging, you will usually find the batch number on the bottom or on the side flap.
Typical markings on the product are “Ch.-B.”, “LOT”, ‘Batch’ or “L” followed by the actual number. Professional labeling ensures that the batch number is permanently legible and correctly positioned.
Batch number in digital systems
In warehouse management systems (WMS) and ERP software, the batch number is recorded digitally and assigned to each item. Barcode or QR code scans allow the batch number to be read automatically during goods receipt, storage, and picking. This means that it is always possible to trace which batch is located at which storage location.
Why is the batch number important?
The batch number fulfills several key functions in production, logistics, and trade. It is much more than just a label on the packaging.
Traceability and quality assurance
The most important advantage of the batch number is traceability. In the event of a quality defect, the batch number can be used to pinpoint exactly which products are affected. Instead of recalling the entire range, companies can specifically block the defective batch and withdraw it from circulation.
In warehouse management, batch management also enables the implementation of the FEFO principle (First Expire, First Out). Products with the earliest expiration date are removed from storage first. This minimizes spoilage and ensures product quality. The batch number also plays a role in returns management when returned goods have to be assigned to a specific production batch.
Legal requirements for batch labeling
In many industries, the assignment of a batch number is required by law. The following overview shows the most important regulations:
| Industry | Legal Basis | Batch Tracking Requirement |
|---|---|---|
| Food | EU Regulation 178/2002 | Yes, mandatory |
| Pharma/Medicines | EU Directive 2001/83/EC | Yes, mandatory |
| Cosmetics | EU Regulation 1223/2009 | Yes, mandatory |
| Medical Devices | EU MDR 2017/745 | Yes, mandatory |
| Technology/Electronics | No uniform requirement | Voluntary, recommended |
Batch number and serial number compared
Batch numbers and serial numbers are often confused, but they serve different purposes. The batch number identifies an entire product group that was manufactured under the same conditions. The serial number, on the other hand, identifies a single, individual product.
While batch numbers are typically used in the food, cosmetics, and pharmaceutical industries, serial numbers are mainly used for technical devices, machines, and vehicles. In warranty processing, the serial number is used to identify the exact individual item. In a product recall, on the other hand, the batch number narrows down the entire affected production quantity.
| Feature | Batch Number | Serial Number |
|---|---|---|
| Identifies | Product group (batch) | Individual product |
| Quantity | Multiple units | Always quantity of 1 |
| Typical industries | Food, cosmetics, pharma | Electronics, machinery, automotive |
| Traceability | By batch | By individual unit |
| Warranty handling | By batch | By individual product |
Batch numbers in fulfillment logistics
In fulfillment logistics, batch management is an integral part of day-to-day business. Fulfillment service providers process products from industries that require batch management, such as cosmetics, dietary supplements, and medical devices, and must ensure complete traceability.
When goods are received, each batch is recorded and stored in the warehouse management system. During picking, the system ensures that goods are removed from storage according to the FEFO principle. This means that products with the shortest shelf life are shipped first.
With over 25 years of experience and ISO 9001-certified quality management, we can ensure reliable batch tracking throughout the entire supply chain. Whether you need to ship individual items with batch verification or large quantities with best-before date tracking, our processes can be adapted to your requirements. If you are looking for a logistics partner with experience in batch management, contact us for a no-obligation consultation.
Frequently asked questions about batch numbers
What is a batch number?
A batch number is a unique alphanumeric code assigned to a specific production quantity. It enables the complete traceability of all products manufactured under identical conditions.
How can a batch number be traced?
A batch number can be traced via the manufacturer’s warehouse management system or ERP software. The code provides information about the production location, date of manufacture, and the entire supply chain of the batch in question.
Where can I find the batch number on a product?
The batch number is usually located on the label, the bottom of the packaging, or near the best-before date. It is often marked with abbreviations such as “Ch.-B.,” “LOT,” “Batch,” or “L.”
What is the difference between a batch number and a serial number?
The batch number identifies an entire product group from the same production run. The serial number, on the other hand, identifies a single product and always has a quantity of 1. Batch numbers are typical for food and cosmetics, while serial numbers are typical for electronics and machines.
