The Center for Devices and Radiological Health (CDRH) at the U.S. Food and Drug Administration (FDA) developed and maintains the Standard Product Nomenclature.

The nomenclature is used to share regulatory information about medical devices.

The nomenclature contains the medical device names and associated information, such as product review codes, definitions, and classification regulation numbers, which reside in CDRH’s Product Code Classification Database.

The nomenclature is used by medical device regulators and manufacturers, healthcare professionals, and the general public for information about medical device approvals and classification.
