What is the typical 2D barcode format utilized to encode the serialized National Drug Code and associated data on individual pharmaceutical containers?
GS1 Data Matrix
For pharmaceutical serialization, the required data set—which includes the unique serialized National Drug Code (NDC), the serial number, the lot number, and the expiration date—must be encoded in a format capable of holding this density of information on a small surface area. The GS1 Data Matrix format is the specified 2D barcode mechanism that fulfills this requirement. Unlike older, linear barcodes, 2D symbologies like the Data Matrix can store significantly more data in a compact space. This capability is vital because the data attached to the saleable unit must be comprehensive enough to allow for verification and tracking throughout the distribution network, a level of detail older linear scanning technologies could not support.
