GS1 Standards Resources for DSCSA Implementation Support

The 2013 Drug Supply Chain Security Act (DSCSA) requires pharmaceutical products packaged after November 27, 2018 to be marked with a National Drug Code (NDC), serial number, lot number, and expiration date.* When using GS1 Standards, the NDC is represented by a GS1 Global Trade Item Number® or GTIN®.

  • Are you a pharmaceutical manufacturer, wholesale distributor, or repackager using GS1 Standards for the Drug Supply Chain Security Act?
  • Are you a retail, hospital, or chain pharmacy who is preparing to receive products and cases from suppliers who are using GS1 Standards to implement the DSCSA?
  • Do You Have DSCSA implementation questions?

Certificate and Customized Education

The DSCSA specifies that packages (“lowest saleable units”) must be marked with a two-dimensional (2D) barcode (e.g., GS1 DataMatrix barcode), and homogeneous cases with either a 2D barcode or linear barcode (e.g., GS1 DataMatrix barcode or GS1-128 barcode, respectively)—which will be accessed by healthcare providers for patient safety.

GS1 US® offers certificate education and implementation best practices to help you prepare for DSCSA by using GS1 Standards to track and trace products at the product and case level.
