UUnique Device Identification

Unique Device Identification (UDI) requirements for medical devices are currently being implemented by the US FDA, and European and Japanese authorities are expected to adopt similar programs in the coming years. The new rules are intended to improve traceability of devices for post-market surveillance purposes, and will have to be met in order to obtain US market compliance. UDI compliance will require significant effort on the part of device manufacturers.

Technimates has carefully followed the development of UDI rules at both the US and international level for several years, and has the expertise and resources to help medical device companies set up compliance processes to meet US FDA UDI requirements.

US FDA UDI Requirements

FDA UDI compliance involves more than just engraving or printing a number onto your medical device or adding a bar code to your label. Several components are involved:

Each UDI must contain two numbers: a device identifier and a production identifier. 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 will be required to submit UDI data into a new FDA database, the Global Unique Device Identification Database (GUDID) using proper formatting. The FDA’s UDI rules will not be fully implemented until 2020, but higher-risk devices will have to comply sooner than that.

How can we help?

Technimates has been working with medical device companies for past decade to support their compliance programs. We can ensure that your FDA medical device registration project includes a fully compliant UDI component through the following strategy:
