Have you been stumped by this one recently: What’s our pharmacy’s GLN? Don’t sweat it. You’re not alone. Drug wholesalers will rely on having a Global Location Number for all their trading partners covered by the Drug Supply Chain Security Act (DSCSA). Customers of AmerisourceBergen, Cardinal Health, McKesson, and Smith Drug may already have a GLN and just need to contact customer support to get it and share with other distributors. The GLN is used in electronic tracing data to identify a location or business in the supply chain. To obtain a single GLN from GS1 US for a 1-time fee of $30, visit here. Companies with more than nine locations may opt to license a GS1 company prefix and manage all the GLNs for the company. More information about pharmacy compliance for DSCSA is available here or email email@example.com.
