Follow our step-by-step plan to allocate medicines a worldwide unique identification number. In this unique product code you also code the other mandatory traceability elements such as expiry date, batch number and serial number.
Step 1: become a GS1 member
To uniquely identify your products worldwide, you need a GS1 company prefix. You obtain this prefix when you join a GS1 organisation and it is always part of a Global Trade Item Number (GTIN). The length of your prefix determines the number of items that you can uniquely identify.
Step 2: Assign a GTIN
Each product and each of its hierarchical levels of packaging must be assigned a separate Global Trade Item Number (GTIN) in order to distinguish them from each other in the supply chain.
Depending on the requirements of the legislation, you add one or more of the following data by means of Application Identifiers (AIs)
- Batch/lot number (alphanumeric, maximum 20 positions)
- Expiry date (YYMMDD, 6 digits)
- Serial number (alphanumeric, up to 20 positions)
Step 3: Convert the identification key to a suitable barcode
You must place both the human-readable identification number and the machine-readable barcode on the packaging. The choice of which type of barcode depends on what information you have encoded. If you only want to encode the GTIN, you can choose an EAN-13 or EAN-14 type barcode. But often legislation requires additional information such as lot number and expiry date to be recorded. In that case, a GS1 DataMatrix is the most suitable. An additional advantage of the GS1 DataMatrix is that you can encode a lot of information in a very compact barcode. You therefore save space on the medicine's packaging.
Step 4: Have the barcode checked
GS1 Belgilux members can have their labels checked free of charge by our barcode checking service. You will then receive an audit report with possible recommendations for corrections.
This way, you can be sure that you are printing a compliant barcode on your packaging.
You can send us a physical sample, but we also accept digital samples.
