Choosing the right route
If you submit high volumes or need automated updates, HL7 SPL via ESG is typically required. Lower‑volume teams may start with the web app and migrate later. If you also need UDI strategy or regulatory support, explore the Cruxi directories hub.
FAQ
What are the two ways to submit data to GUDID?
FDA provides two submission paths: (1) Manual entry via the GUDID web app for low-volume submissions, and (2) HL7 SPL XML file submission via the FDA Electronic Submissions Gateway (ESG) for bulk/higher-volume submissions.
When should I use HL7 SPL instead of the web app?
Use HL7 SPL via ESG for higher-volume or bulk submissions, when you need automated workflows, or when integrating with existing UDI data management systems.
