In UDI, what are Production Identifiers (PI)?

Device identification

The type of device is identified with a code known as a Device Identifier (DI). 

Production identification

Production identification refers to the information that identifies a medical device to a more granular level, either to an instance by using a serial number or by using batch number and dates. This is known as the Production Identifier (PI).  

This production information will change dynamically for every manufacturing batch.

Common PIs used on medical devices include: 

When we look at these identification codes in relation to the UDI regulations, they are known respectively as UDI-DI and UDI-PI.

The specific production information cannot be entered into any regulatory databases - you normally indicate what types of production information are included on the label and in the barcode.
