What is a NTIN Data Matrix barcode?
An NTIN (National Trade Item Number) is a GS1-compatible 14-digit number built from a national pharmacy code, such as the German PZN with the GS1 prefix 4150. It lets national product codes be carried in GS1 barcodes alongside regular GTINs.
The code is a GS1 Data Matrix with Application Identifiers: (01) for the NTIN, (17) for the expiry date as YYMMDD, (10) for the batch and (21) for the serial number. Many European serialization systems under the Falsified Medicines Directive accept this layout.
Choose NTIN Data Matrix when your market uses GS1 coding with a national number. If you work with the IFA PPN format instead, use the PPN / IFA Data Matrix generator.
What data can NTIN Data Matrix hold?
GS1 Application Identifiers in brackets, for example (01)04150123456782(17)271231(10)LOT42(21)SN0001. For (01), enter 13 digits and we add the check digit, or all 14 digits and we verify it.
Recommended size
Keep a quiet zone of at least one module around the code. Follow the GS1 and national guidance for module size on pharmaceutical packs, and verify the print quality before release.

Frequently Asked Questions
It has the same 14-digit structure and check digit, but it is derived from a national code rather than from a company's GS1 prefix.
A common order is (01), (17), (10), (21). Follow your market's coding guideline, as some systems expect a specific order.
Yes. The GS1 Data Matrix is encoded with the required FNC1 start and separators, so you only type the bracketed AIs.
