CDRH Industry: FDA Issues Draft Guidance on the Unique Device Identification System: Form and Content of the Unique Device Identifier (UDI)

Posted on Posted in News and Events, US FDA

Today, the U.S. Food and Drug Administration released a draft guidance document, “Unique Device Identification System: Form and Content of the Unique Device Identifier (UDI).”  The Unique Device Identification System Rule (UDI Rule) requires the label and device packages of most medical devices to bear a unique device identifier (UDI) in both easily readable plain-text and automatic identification and data capture (AIDC) technology forms. UDIs must be issued under a system operated by FDA-accredited issuing agencies (IAs).

This draft guidance is intended to assist both labelers and FDA-accredited IAs better ensure the UDIs developed under IA systems are in compliance with the UDI rule.  It includes clarification on:

  • Two forms of a UDI;
  • Content of the UDI (including data delimiters that identify specific data elements within the UDI); and
  • Order of data in a UDI and UDI carrier (the means to convey the UDI and any non-UDI elements in easily readable plain-text and AIDC forms).

We welcome your comments regarding this draft guidance. The comment period closes in 60 days.

For more information about the Unique Device Identification System, please visit the FDA’s UDI webpage.

If you have any questions, please contact the FDA UDI Help Desk.

Thank you,
