What is UDI?

UDI is a globally unique numeric or alphanumeric code that consists of two parts

Unique Device Identification, or UDI is a regulatory requirement first enacted by the US FDA, and now adapted by regulatory agencies around the world. UDI enhances patient safety by identifying each product with a static device identifier denoting the device labeler and the specific model or version of a device and the dynamic product identifier which identifies the expiration date, serial number, manufactured date or the lot/batch number of the device. While the UDI is created through the guidelines of an approved issuing agency, the medical device manufacturer is responsible for performing a submission of the identifier along with several product data attributes. If all of this sounds confusing, Reed Tech is here to help.
