Global Unique Device Identification Database (GUDID)

The Global Unique Device Identification Database (GUDID) is a database administered by the FDA that serves as a reference catalog for every device with a unique device identifier (UDI).

GUDID contains ONLY the device identifier (DI) portion of the UDI, which serves as the key to obtain device information in the database. While GUDID does not include production identifiers (PIs), GUDID contains PI flags to indicate which PI attributes are in the UDI.

August 14, 2023 - The AccessGUDID Database has been updated to include the field for Global Medical Device Nomenclature (GMDN) Code along with the status of the GMDN Code, Active or Obsolete. If a labeler submitted an FDA Preferred Term (FDA PT) Code to meet their GMDN Code data entry requirement, the equivalent GMDN Code will now be released publicly. 

These new fields are available in AccessGUDID and the openFDA Unique Device Identifier endpoint. This latest update is intended to provide the end user with enhanced search and retrieval capabilities for GUDID data.

Resources are available on the GMDN website to help labelers identify appropriate GMDN Term Codes for their products including alternatives to obsolete term codes.


Device Labelers: Submit Data to GUDID

The FDA provides device labelers with two options for submitting data to GUDID: the manual data entry via GUDID web application (for entering data for one device at a time) and HL7 SPL submission via FDA Electronic Submissions Gateway (for bulk uploads). For details on each option, see Submit Data to GUDID.

GUDID Data Quality

To fully reap the public health benefits and a return on investment of the UDI system, FDA is focusing resources on optimizing the quality and utility of data in the GUDID database, which appears as publicly releasable data in AccessGUDID. FDA is also committed to working with industry to ensure widespread use and sustainability of the UDI system. For details, see Optimizing GUDID Quality.


GUDID Data Trends

Each month, the FDA produces presentation slides summarizing patterns and trends in the GUDID data. These presentation files are available for download. For details, see GUDID Data Trends.
