(UDI) Each issuing agency has its own specified format for representing the two main components of a UDI – the Device Identifier (DI) and Production Identifiers (PI). The device identifier is a mandatory, fixed portion of a UDI that identifies the specific version or model of a device and the labeler of that device. The production identifier is the conditional, variable portions of a UDI that identifies one or more of the following when included on the label of the device and include: lot or batch within which a device was manufactured; serial number of a specific device; expiration date of a specific device; date a specific device was manufactured; and for an HCT/P regulated as a device, the distinct identification code required by 21 CFR 1271.290(c). The format of each issuing agency’s UDI is outlined in the tables below. These issuing agencies maintain responsibility for the uniqueness of their device identifiers.
