Medical Device UDI (Unique Device Identification) Consulting and Training


  • How does the US FDA UDI system work?
  • When must we comply with UDI system requirements?
  • Which device classifications need to comply with UDI requirements?

Unique Device Identification (UDI) requirements for medical devices have been implemented by the US Food and Drug Administration (FDA). The FDA issued the final Unique Device Identifier (UDI) Rule and published it in the US Federal Register on 24 September 2013.

The UDI system final rule provides standard device identification and accompanying identifying information to support various public health initiatives, including support for the FDA’s post-market surveillance (PMS) activities. Manufacturers must meet UDI requirements as part of US market compliance.

UDI compliance requires a significant effort on the part of manufacturers. Emergo has carefully followed the development of UDI rules in both the US and international markets and has the expertise and resources to help you establish compliance processes to meet US FDA UDI requirements.

How the US FDA UDI system works

FDA UDI compliance involves more than etching a number onto your medical device or adding a barcode to your label. Several components are involved.

Each UDI must contain two numbers: a Device Identifier (DI) and a Production Identifier (PI). A Device Identifier must correspond to the specific model or version of a medical device and the company name. A Production Identifier must provide a medical device’s lot or batch information or serial number, expiration date, and related production data.

  • Class I devices must be assigned device identifiers only. Class II and III devices must be assigned both device identifiers and product identifiers.
  • Manufacturers must obtain UDI numbers only from FDA-accredited issuing agencies.
  • All medical devices registered for sale in the US will have to include UDI information on their labeling and packaging.
  • Devices intended for more than one use as well as devices requiring reprocessing before each use must also have UDI data marked directly on them.
  • Manufacturers must provide UDI information in both plain-text (human readable) and AIDC (Automatic Identification and Capture) formats.

Manufacturers are required to submit UDI data into the FDA Global Unique Device Identification Database (GUDID) using proper formatting. To learn more about the requirements, download our free white paper: Understanding the US FDA UDI Regulation.
